The present study determines the effect of compression over bioimpedance of healthy soft tissue (in-vitro and in-vivo). Electrical impedance spectroscopy (EIS) is a promising tissue characterization and tumor detection technique that uses tissue impedance or admittance to characterize tissue and identify tissue properties as well as cell structure. Variation in EIS measurements while applying pressure suggests that compression tends to affect soft tissue bioimpedance. Moreover, the displacements in tissue caused by applied compression may provide useful information about the structure and state of the tissue. Thus combining the changes to the electrical properties of tissue resulted by applied compression, with the changes in tissue displacements caused by applied compression, and consequently measuring the effect that electrical and mechanical properties have on each other, can be useful to identify tissue structure. In this study, multifrequency bioimpedance measurements were perfo rmed on in-vitro and in- vivo soft tissue at different pressure levels. Increasing compression on the in-vitro tissue results in an increase in both extracellular resistance and membrane capacitance while it causes a reduction in the intracellular resistance. However, as the compression over the in-vivo samples increases, the intracellular and extracellular resistance increase and the membrane capacitance decreases. The in-vivo measurements on human body are also tested on contra- lateral tissue

Tom BrokawÃ¢â¬â¢s The Greatest Generation In Tom BrokawÃ¢â¬â¢s book, The Greatest Generation, the author portrays ordinary people of a certain generation as having qualities of greatness and heroism. He tells stories of average people that lived inspiring lives through many hardships, and declares todayÃ¢â¬â¢s society as the beneficiary of their challenging work and commitment. BrokawÃ¢â¬â¢s generous and proficient use of imagery helps to persuade the reader to believe that the people of Ã¢â¬Å"the greatest generationÃ¢â¬ are, indeed, heroic. He defines the strength and resilience of Ã¢â¬Å"the greatest generationÃ¢â¬ by what they were able to confront and overcome.

Ã¢â¬Å"What those unsuspecting infants could not have realized, of course, was that these were temporary conditions, a false spring to life that would be buffeted by winds of change dangerous and unpredictable, so fierce that they threatened not just America but the very future of the planet.Ã¢â¬ (p4) BrokawÃ¢â¬â¢s use of imagery here helps the reader understand the drastic nature of the change that occurred in the world between the 1920s and 1940s. He is stating that the youth of our nation was living in a safe-harbor for only a short period of time, almost as if under false pretenses, and that this promising future of America veered radically off a path as they had to face the unprecedented crash of the stock market, with damage so great that over a thousand banks would close, millions of people would become unemployed and homeless, and an overwhelming sense of economic calamity would sweep the feet out from under their fragile vision of security. Brokaw described this in the c hapter titled Ã¢â¬Å"The Time of their Lives,Ã¢â¬ as a time when Ã¢â¬Å"A mass of homeless and unemployed drifted across the American landscape.Ã¢â¬ (p7) This gives the reader an image of millions of people hopelessly wandering the country in search for work to survive.

Political discrepancy: as we are a company that has an agreement with Qatar government for the supply of natural gas, It Is Important to keep our good relation with the country to continue the business. New source of energy: Dolphin Energy is a company that supplies gas to the customers, in case of finding any applicable source of energy for gas that is less costly and has no impact to the environment, our company will shut down and loses its business. Ã¢â¬â Price changes: If the prices of the equipment used in the operation escalated, the price of our product will increase. We will write a custom essay sample on CIPD or any similar topic only for you Order Now Ã¢â¬â New competitor: another external factor that would affect the company is if there is a new company of gas Joining the market. Such competitors will affect our market price, It will have an effect on our manpower costs, people will compare the quality of the product produced, etc. 5- How the business is structured: Dolphin Energy has so many functions that plays Important role in the organization. Below, I will be explaining only four functions. Our companyÃ¢â¬â¢s structure Is considered functional structure because It has similar connected actively that are grouped together in departments. Function Discretion Corporate Communications DolphinÃ¢â¬â¢s corporate communications department handles all communication undertaken by the company to all its publics or stakeholders. Strategic and Corporate Planning It is responsible for all economic and corporate planning duties at Dolphin Energy. SHE It is responsible about the laity of the products, the health of the employees, the safety of the working area, and making sure they are taking good care for environmental issues. Human Resources They offer services to their employees in Talent Management, recruitment, policy, compensation, employee relation, training, and office management. O- Different functions working together: Dolphin Energy works with different departments very closely in order to make sure operation, the operation works closely with different departments to ensure they are meeting their objective. For example, operation works with human resources to circuit quality employees that have all the required qualifications skills that are needed for technical skills. Moreover, when an employee Joins the company, operation department will want their new Joiners to undertake some kind of trainings to enable them have the needed skills to operate in the field. Quality, health, safety and environment department as well works with other functions to reach their goals. SHE facilitates everything that is necessary in the operational area to ensure that the employees are working in a safe environment to minimize all the risks that might occur during the operation. SHE will also make sure that our equipments and machines do not harm the marine habitat and cause and eruption or pollution. Furthermore, SHE wants to educate the employees about some safety matters and they co pop with the training department to implement such trainings. 7- The culture of the organization and how it affects the operations: I believe Dolphin Energy has a mixture of task and power culture. It is considered a role culture because each employee is assigned to a particular role or Job; they have all their tasks and roles listed in their Job description. When we have everything pacified, it will help us know what each individual does and therefore no duplication in work. On the other hand, we can say that our organization is a task oriented culture as well. That is because Dolphin I-JAKE and Qatar work together in so many projects as a team to complete tasks for example, our training department in I-JAKE works with StarÃ¢â¬â¢s to reach the departmentÃ¢â¬â¢s goals and objective. The teams will be doing a specified task to complete it in a time and budget given. This mixed culture has a positive impact on the organization because it will get the most efficiency out of his effort through having everything with guidelines yet working in teams in common projects and assignments. Activity B: 1- Organization Strategy: The companyÃ¢â¬â¢s strategy is to have an economic wealth as well as creating business prospects for I-JAKE nationals and ICC citizens for the future. Our company has clear vision and mission that is set which makes the employees well aware of where the company is heading and what is their future objective. Having the vision and mission clear will create order; therefore will help us in proportioning our tasks. 2- How does HER strategy supports the organization strategy? The HER does a lot of things that supports the organizations strategy. Starting from recruiting a competent employee to developing them. The HER work closely with other departments as one team to reach the organizationÃ¢â¬â¢s strategy. Below is a list of some the things the HER does to support Dolphin Energy Objectives: HER Strategy Supporting OrganizationÃ¢â¬â¢s Objectives Recruitment HER uses the best ways to hire an employee. For example, we deal with hiring agents that would get us the best people in the market. Moreover, we hire people through referral programs where an existing employee refers someone who is capable to take the Job. As well, HER have internal posting for the employees who would recommend themselves to undertake the posted position. We use technology for the hiring process; candidates can now view all the open posts on our website to compensation team participates in researches, surveys and benchmarking with companies who similar to us so we are updated with the latest paying trends and we are competing with similar industries in the market. When the company does such things, it will retain current employees specially the high potential and talented ones. Retain Talent Management One thing TM is responsible for is induction sessions which the new Joiners undertake to familiarize them with the companyÃ¢â¬â¢s departments and its work nature. This will help the employee adapt faster and work more effectively when working with different divisions. Different development plans for fresh graduate students and existing employees. Offering scholarships and sponsorship to educate our employees and make them update their skills and knowledge to achieve the companyÃ¢â¬â¢s goals. Having high potential programs and succession planning which helps the employees get motivated and it will encourage them work harder to achieve the companyÃ¢â¬â¢s strategy. Ã¢â¬â How can HER/LD professional support line managers and their staff? The HER and learning and Development support line managers in so many different ways. Some of these things are: Ã¢â¬â HER helps line managers in recruiting well qualified candidates to fill the vacant position. They do that through scanning C.V. and looking for candidates that has the skills required for the Job and then they do interviews and psychometric tests for them. When HER hires high talented people, it will help them accomplish work in efficient and effective way to meet the business goals. This way the HER will be eating the best talent out there in the market. Ã¢â¬â Learning and development helps the new Joiners have a brief orientation through all the departments in the company to give a good idea about the business and how each department operates. This will help the employees know everything about our business and help them work better with the division to achieve the goals of the company. Ã¢â¬â Having HER updates sessions that would help the HER employees and line managers know the latest updates that is happening in the HER which will help them understand how the process is and what HER services is offered. Offering best practices in Learning and development, which will encourage and motivate the employees to perform better. Ã¢â¬â Help line managers to achieve their KIP to achieve the organization objectives. Ensuring that the employees are working in a good working environment. 4- How does HER/LD contribute in the successful of an organization? To define success, first we need to know what things that makes the organization successful. Organizations have a lot of objectives each year, general objectives will be ambiguous, so one of the keys to success is to have a clear objectives. For example, avian clear mission, vi sion, strategy and goals clear and it should be known to everyone throughout the organization. Everything the organization does, for example, the policies and procedures that are written, he different types of programs we offer, the services we provide, etc are all clearly linked to the companyÃ¢â¬â¢s objectives for being successful. Lurch mentioned, there are four ways to a successful organization strong relation with their internal clients and they act as a focal point for certain divisions. This can be done by having good relation with the senior management in order to align the HER strategy with the business objectives. Change Agent: is the team that participates in changing the management team and then communicate internally to everyone to ensure smoothness of the process and then gain their trust. Change agent will ensure that the employees are adapting to new changes. Ã¢â¬â Administration Expert: it acts in a professional in the way that it executes its Job and uses the organization resources in an efficient manner. Ã¢â¬â Employee Champion: it plays as a core of the HER. HER should represent the employees, look for their best interest and make sure that strategic initiatives are balanced.

Thomas More: The Hypocritical Martyr Thomas More: The Hypocritical Martyr Thomas More should not be on the pedestal that people tend to put him. His stance against the divorce that King Henry VIII wanted does not make him righteous or even close to it. More felt that divorce would go against the principles of the Bible, yet his work, Utopia, also goes against the teachings of the Bible. Just as Henry wanted to create his own church to satisfy his own needs, More's Utopia is a society created to fit his needs. To begin, we must look at the utterly blasphemous comment that More makes relating his Utopian society to Christ. And I have no doubt that either self-interest, or the authority of our Saviour Christ ?would have led the whole world to adopt the Utopian system long ago (More 131). With this comment, More is saying that he knows what is best over Christ, his God. He is in the same boat with King Henry, who created his own church feeling that he knew better than God that divorce was correct. The only way More could prove his bold claim is to align his society with the teachings of the Bible. The only problem is that he fails to do this. More's first attempt to making his claim correct was close to the teachings of the Bible. When writing through the character Raphael, he claims that the Utopians view that, happiness is the summum bonum towards which we're naturally impelled by virtue- which in their definition means following one's natural impulses, as God meant us to do (More 91). This is true when you consider the Garden of Eden. Adam and Eve were given all of the needs and desires of their hearts, before they turned their backs on God and ate from the tree of knowledge. This introduced sin into the world, which made man's natural impulse to follow his own way and sin against God. The footnote given in the text says that the quote is an Epicurean view. Epicureans were pleasure seekers who were fully devoted to sensual pleasure. Christ would not have accepted this behavior. The Bible states in Col 2:23: Such [basic principles of the world] indeed have an appearance of wisdom? but they lack any value in restraining sensual indulgence. It teaches that the senses, which are naturally in all humans, should be controlled. Jesus himself was tempted for 40 days and nights straight, but did not give in to seeking pleasure in those temptations. The Utopians could be free to seek pleasure anywhere if sin was not in the world, but it is. Christ knew this, and therefore would not subscribe to the society's beliefs. More again tries to make his society closely related with the teachings of Christ in the way Utopia tries to rid itself of greediness. He felt that social organization was to blame for greediness: No living creature is naturally greedy, except from fear of want? but there's no scope for that sort of thing in Utopia (More 80). Again, this is not true according to the Bible. Eve was greedy by eating the fruit of knowledge so that she would have the wisdom of God. Since Eve was the first woman in creation according to the Bible (which Thomas More himself embraced) and she was greedy, it is safe to say that all humans are naturally greedy. By More saying that no living creature is naturally greedy, he is saying that there is some good in us, which is not true according to the Bible. Romans 3:12 says, All have turned away, they have together become worthless; there is no one who does good, not even one. More has a point that greed is wrong and we should not be greedy, but to think that we begin in life with some amount of good is against the teachings of the Bible, and therefore would not prompt Christ to accept this perfect society. Towards the end of the book, Utopia becomes somewhat of a heaven on earth as it begins to sit on the judgement seat of God in a sense. Utopia does not believe in war and will do anything they can to get

Children in the Third Reich essays The education of the children was of paramount importance to the Nazi party during the Third Reich. By educating the children in the beliefs and ideals of the Nazis they believed that they would perpetuate their political system for the thousand year Reich. They achieved this by controlling all flows of information; principally the arts, the education system and controlling the media. 1. Describe and explain the policies the Nazi government attempted to implement The belief in Nazi ideals (racism, national pride, belief in the family unit, clean wholesome living) Art was considered to be one of the most important elements to strengthen the Third Reich and purifying the nation. Political aims and artistic expression became one. An example of this would abstract art. The Nazis didnt consider this art; therefore the opinion of the Hitler youth towards abstract art was changed. This type of art wasnt approved of because it didnt promote family values. Hitler had his own ideas of what education should entail. He thought it should preserve, care and develop the best racial elements. The youth of Germany was made to worship Hitler. A picture of him was hung in every classroom. Hitler was well aware of the fact that for this regime to survive, there must be support from future generations. He had planned for this by creating the Hitler Jugend (Hitler Youth). This was Hitlers tool to ensure that the younger generation would be completely loyal to the Nazi regime and would be willing to fight in an upcoming war. He called them the guarantee of the future. Hitler felt the Hitler Youth as the only organization that he could trust as he saw them as being unattained by the Weimer Republic. Seeing this trust makes you understand why he gave the Hitler Youth such important responsibilities and duties over the war years. ...

8 Benefits to Start a Homework Writers Career 8 Benefits to Start a Homework Writers Career We feel your pain. This is a lot harder than you thought it would be, isnÃ¢â¬â¢t it? You want to achieve stunning grades in your classes, but you also need to work as much as you can to finance your education at the same time. So youÃ¢â¬â¢re a burning candle at both ends. What if you could combine your studies with a lucrative career succeeding in your classes and at your job at the same time? Consider starting a career as a homework writer. Here are some of the benefits that you will gain: 1. Convenience Even work-study jobs require at least a minimal commute eating up your valuable time. But homework writers can do their job from the comfort of their own apartments or dorms. Imagine coming home from the university and being able just to sit down at your desk and earn some cash. 2. Flexible Schedule Did you oversleep this morning? Or do you have a test to study for the whole night? No worries; it wonÃ¢â¬â¢t impact your work schedule. You can choose your hours and work when itÃ¢â¬â¢s convenient for you. 3. Building a Professional Reputation The fact is that you are a research and paper-writing expert. Once youÃ¢â¬â¢ve gained a few clients, buzzes about your expertise will spread around the campus. This can help you especially if you are considering the education field for future employment. 4. Earning Extra Money As a college student, you have many things to budget, so at times it is quite hard to make ends meet. WouldnÃ¢â¬â¢t it be great to have extra money on hand for entertainment, food, and tuition fees? A little extra spending cash would definitely relieve some of your worries. 5. Gaining New Knowledge and Skills Why do college instructors assign homework papers in the first place? ItÃ¢â¬â¢s because the completion of these tasks helps you learn more and improves your knowledge. So just imagine how knowledgeable you will become if you are completing not just your own assignments, but those of your clients as well. You can acquire learning in a variety of areas, and will therefore be able to converse intelligently about everything from social science to math, from literature to medicine. That well-rounded intelligence will make you very appealing to future employers. 6. Gaining Experience Any employment gives you something to add to the Ã¢â¬Å"work experienceÃ¢â¬ section of your resume. You will have a distinct advantage over those who have never had a job, or even those who just worked as a dishwasher or a store clerk. 7. The Opportunity to Help People Your clients are struggling students, just like you. You have the opportunity to make their lives just a little bit better and easier. You are reducing their stress by offering help when they need it. 8. Getting to Know Different People College is supposed to be the time for meeting new people and building friendships. But often students find themselves under such stringent demands that they just donÃ¢â¬â¢t have time to seek out new acquaintances. As a smart homework writer, you will meet a lot of students. Your world will become a richer place for getting to know international students, mature students with jobs and families, and those from low-income backgrounds. These are people that you might never get to meet otherwise. Becoming a homework writer can expand your horizon and opportunities in many ways. So, go ahead and embrace the opportunity.

Homework assignment - Research Paper Example Over the years, many employers have been faced with the dilemma of having to recruit workers but they lack ideas of how to get the right person for the job. This happens in situations where someone may require a house help, mechanic, electrician and many more to work for an individual. An example of the problem is that an individual may be travelling and their car experiences a mechanical breakdown and you are unaware of how to deal with this problem. This site will help an individual get a mechanic near their location. This section outlines the approach to the problem described above. The approach is from Foster et al. [2, Sec. 6], which discusses a scenario of service-based distributed query processing using OGSA-DAI. The key idea is to make the data available to all the users via a web service with the help of Grid Distributed Query Processing Service techniques (GQPS). An adequate method of solving this problem is to create a web browser where all interested personnel can sign up and fill a form which involve entry of personal details like; location, age, profession among others (Oliver, 2005). All those who sign up will have an account with their details that will be stored in a database. The web interface will contain a search option which will enable anyone interested in getting a worker will enter the profession and a list of all those in that category of profession will be. In case the employer needs some from a particular area, he or she needs only to specify the area while searching (Converse, 2004). The design delivers a web based interface for data access. The intended deliverable of this project is the development of a site for data access search of professions in a distributed environment, which indeed will provide more opportunities for work applications in real world scenarios (Vikram, 2005). The site will also have a rating system through which service providers can be rated. This is vital information that employers

How eukaryotic organisms came into existence Living systems (LST) are self-organising systems that interact with the environment. Flows of information, energy and matter maintain these systems in order and balance. Miller (1978) defines LST as a set of related definitions, assumptions, and propositions which deal with reality as an integrated hierarchy of organizations of matter and energy. LST is as an excellent and powerful tool in aiding an individual to understand and interpret reality, especially its living part. However when it comes to intervention, design and change, the LST gives little or no guidance concerning what to do and what actions and approaches to select. So although the LST provides extensive amount of knowledge in regards to life and living systems nevertheless it mentions nothing to do with that knowledge. Multicellular organisms are thought to have evolved at least 1.7 billion years ago; organisms consisted of many or more than one cell which have interdependent cells (differentiated cells) that perform s pecialised functions in an organism. Examples of multicellular organisms are humans, plants and animals which can be seen by the naked eye. Cells are separated into two main classes primarily by whether they contain a nucleus. Prokaryotic cells (bacteria) lack a nuclear envelope whereas eukaryotic cells have a nucleus in which genetic material is split from the cytoplasm. In general prokaryotic cells are smaller and simpler than eukaryotic cells. In addition to the absence of a nucleus prokaryotic genomes are less complex and they do not contain organelles in its cytoplasm or cytoskeleton. In spite of all these differences, the same basic molecular mechanisms manage the lives of both prokaryotes and eukaryotes which indicate that all present-day cells have descended or evolved over time. The endosymbiotic theory explains and provides evidence of cell evolution which claims that bacteria cells evolved to animal and plant cells by phagocytosis through a process called endosymbiosis. [endo=inside; sym=together; bio=life]. Symbiosis describes the close relationship between two or more organisms of different species, where they are not always benefiting each member. The relationship of algae and fungi in lichens and of bacteria living in the intestines or on the skin of animals are forms of symbiosis. Some scientists believe that many multicellular organisms evolved from symbiotic relationships between unicellular ones and that the DNA-containing organelles within certain eukaryotic cells (such as mitochondria and chloroplasts) are the product of symbiotic relationships in which the participants became interdependent. A significant step in the breakthrough of the evolution of eukaryotic cells was the knowledge gained of membrane-enclosed sub-cellular organelles, allowing the progress of the complexity characteristic of these cells. The organelles are thought to have been acquired as a result of the relationship of prokaryotic cells eukaryotes. Studies show that the theory of endosymbiosis shows evidence that origin of mitochondria and chloroplasts which are organelles of eukaryotic cells are thought to have evolved from bacteria living in larger cells. Both chloroplast and mitochondria are similar to bacteria in size and like bacteria they reproduce by a process called binary fission. The American microbiologist Lynn Margulis formulated the endosymbiosis theory that mitochondria and chloroplasts evolved from prokaryotic bacteria. Although now an acknowledged theory and biologist, she and her theory were rejected by many biologists for a number of years, her breakthrough came due to her persistence, and vast amounts of research and data gathered by her and many other biologists over the last 30 years. The discovery of mitochondria having similarities in structures played a key role in making her theory widely accepted by the science world. According to her hypothesis these mitochondria and chloroplasts originated as separate prokaryotic organisms that were taken inside the cell as endosymbionts. Mitochondria evolved from aerobic bacteria (proteobacteria) and chloroplasts from photosynthetic bacteria (cyanobacteria). The contraction of aerobic bacteria would have provided an anaerobic cell with the ability to carry out oxidative metabolism. The acquisition of photosynthetic bacteria would have provided the nutritional freedom given by the ability to perform photosynthesis. The Endosymbiotic theory proposes that mitochondria and chloroplasts were once prokaryotic cells, living inside larger host cells. The prokaryotes were known to have been ingested in the larger cell but somehow escaping digestion. It is not known for the reason why they were ingested and interned but purely for advantageous reasons to the host cells which ingested them. The endosymbionts provided crucial nutrients to the host cell by chloroplasts and the mitochondria helping to have exploit oxygen from extracting energy. The endosymbionts were protected with in a safe environment inside the host cell which they lived for many millions of years. Charles Darwin (1809-1882) theory of natural selection which we know today from the famous quote of Survival of the fittest supports the endosymbiosis theory. Early eukaryotic cells gained an advantage over their neighbours, once mitochondria (high energy source), were ingested in larger host cells. Mitochondria and their hosts increasingly were relying more and more on each other to survive. Eventually, neither could succeed alone but as a force united they produced millions of descendents, establishing a whole new domain of life. Both organelles are surrounded by two or more membranes where the innermost of the membranes show differences in composition from other membranes of the cell. The composition is like that of a prokaryotes cell membrane, while the outer membrane may have formed from food vacuoles as the host cell devoured the prokaryote. The inner membrane of these mitochondria and chloroplasts contains enzymes and transport systems, showing more similarities to that of prokaryotes. The inner membrane of mitochondria has a larger surface area which arose due to the inner layer being folded into what is called cristae. This is turn means that there is more area for the respiratory reaction occur in the organelle. Mitochondria can be found in they cytoplasm of eukaryotic cells similar to shape and size to chloroplasts. The primary function of mitochondria is the production of ATP which is an energy source vital for the proper functioning and survival of the organelle. The outer membrane is a relatively simple phospholipid bilayer, ions, nutrients; ATP, ADP, etc. can pass through with ease. The matrix is where diffusion happens, this is a very slow process due to the folds of the cristae, the matrix is close to the inner membrane, resulting in the diffusion rate to the inner membrane complexes and transport proteins within a short time. Chloroplasts are only found in plants, with a similar function to that of mitochondria, where they both provide energy in the cell. There appearance is that of flattened discs, using a process called photosynthesis to extract carbon dioxide from the surrounding and converting and releasing as oxygen to form glucose, which is stored a starch a food source. Chloroplasts are complex organelles which differ to those of mitochondria, as chloroplasts have there a double membrane called the chloroplast envelope and membranes of thylakoids inside. Chlorophyll is vital and is found in thylakoids membranes in the chloroplast, it is a coloured pigment which converts light energy for photosynthesis. Thylakoids are fluid-filled sacs stacked up in the chloroplast to form structures called grana. Grana which are flat thin pieces of thylakoids membrane are linked together by lamellae. Mitochondria and chloroplasts both have their own DNA molecules. Their DNAs are not duplicates of nuclear DNA but their DNA is exclusive and vital to the mitochondrion or the chloroplast. Genes are carried by mitochondrial DNA; these genes are replicated each time the organelle divides, and the genes they encode are transcribed within the organelle and translated on the organelle ribosomes. Thus mitochondria and chloroplasts contain there own genetic systems, which are distinct and dissimilar to the genetic material of nucleus. Unlike the DNA in the nucleus, mitochondrial and chloroplast DNAs are exposed and circular similar to that of a prokaryotic cells DNA. Genes of the nucleus can not duplicate these. Each organelle has its own ribosomes; these ribosomes are different to those found in the cytoplasm of a cell. The proteins coded for by the mitochondrial genes are produced by mitochondrial ribosomes, and those coded for by the chloroplast genes are produced by chloroplast ribosomes. These ribosomes are more closely related to those of bacteria that those encoded by the nuclear genomes of eukaryotes. Bacteria show more similarities to these organelles as size is also a similarity. To conclude on the question on discuss how eukaryotic organisms came into existence, I believe that the evidence and information regarding the theory of endosymbiosis is reliable but not 100% valid as there are many counter arguments to Lynn Marguliss theory. Numerous studies of DNA show that in fact mitochondria and chloroplasts do not show many similarities that of prokaryotes. For instance neither mitochondria nor chloroplasts can survive in oxygen or outside of the cell indicating that the cell would have lost many vital genes on the way. However both mitochondria and chloroplast are similar in size to prokaryotes, they lack a normal nucleus found in eukaryotic cells but have circular DNA which lacks histones similar to that of eukaryotic cells. Also symbiosis supports the fact that the host cells became dependant on the organelles which it ingested and the lack of DNA within the nucleus and the organelles having their own DNA explains that they would have been independent cells. Both organelles reproduce by division in a process called binary fission, prokaryotic cells also reproduce the same way. On the other hand there are many questions still to be answered. How did the cell manage to reproduce in such a tight space and inside another cell? How did the DNA of the ingested cell pass into the hosts DNA, as the DNA should have been blocked as the host would have responded by degrading the foreign DNA and detect it as a virus. However this can be counter argued against as similarities in structure of both organelles can prokaryotic cells can be explained by their functions and processes and not through their structures. In photosynthesis both chloroplast and cyanobacteria convert carbon dioxide and water with light energy into glucose and oxygen. Nevertheless there is more evidence to sustain the endosymbiotic hypothesis; the evidence outweighs the questions and arguments against. Lynn Margulis theory of endosymbiosis is widely used and accepted by the scientists and science world of today and the more valid and important ideas of the origin and evolution of the cell are of creationists. Finally I agree with the argument that some eukaryotic cells have derived and evolved from prokaryotes and the theory of endosymbiosis seems valid and vital in the way we understand evolution of the cell today.

Why Is Reality T. V. So Popular? It would be difficult to find an hour of the day when a reality television show isnÃ¢â¬â¢t on. What exactly is the appeal of reality television that has so many viewers completely hooked? Why has the popularity of reality TV spanned all socio-economic statuses, age groups, and education levels? Perhaps itÃ¢â¬â¢s the unscripted glimpse you get into other peopleÃ¢â¬â¢s lives that helps take the focus off present troubles, or makes everyoneÃ¢â¬â¢s day to day lives seem a little less Ã¢â¬Å"crazy. Whatever it is that draws reality TV fans in, this fairly new phenomenon has certainly taken the entertainment industry by storm. LetÃ¢â¬â¢s take a look at some possible reasons the popularity of reality TV continues to grow. Voyeurism . It's the reason traffic backs up when there's a horrific car crash Ã¢â¬â we just want to look. Reality stars have the lack of embarrassment we often wish we had, but more often than not, are glad we don't. Admit it. In your head you've smacked a thousand snotty girls or meat headed guys across the face.We all dream of having an excuse to get into a fist fight, just to show what we've got. Well reality stars have found their excuse Ã¢â¬â the camera Ã¢â¬â and we'll keep watching as long as they've got punches to throw I don't think I'm taking a huge leap here by saying that reality TV stars aren't the sharpest tools in the shed. Let's remember that these are people who are knowingly exploiting their personal lives for a little cash and fifteen minutes of fame. Reality stars can, however, be depended upon for one thing.When a delicate situation arises, that requires proper judgment, clear thinking, and caution, reality stars will without failure, make the wrong choice. This is great for us because we can learn from them. We can learn what not to do in almost any situation, and their flagrant disregard for logic, can be our guiding light. Our daily lives require a lot of mental energy. Our j obs our stressful and challenging, and often our personal lives are even worse. Our minds are constantly being taxed and drained.Who wants to come home and escape by turning on entertainment with substance? I don't know about you, but after a long day of thinking, I can't handle substance. I want fluff Ã¢â¬â pure, unadulterated fluff. The less I have to think to understand what I'm watching the better, and luckily, reality TV requires no thought at all. The popularity of reality TV shouldn't come as a surprise considering the fact that we live in a culture that worships vanity, rather than virtue, and lives by the mantra of Ã¢â¬ËHe with the most toys lives,' rather than Ã¢â¬ËHe with the most joys lives. It's been said that circumstances don't make a man, they only reveal him. Likewise, reality TV is merely a reflection of what our society has become Ã¢â¬â a materialistically driven society where the love of power and money overcomes the power of love. It's a reflection of a society that is not only devoid of a solid wholesome value system, but is also separated from spiritual roots. It's also a culture that thrives on living on the edge, characterized by thrill-seeking and addictions.
