Biology Questions and Answers Essay 2.) a) proteins b.) i) Amylase ii) Protease iii) Lipase c) i) Glucose ii) Amino Acids iii) Fatty acids and Glycerol 3.) a.) Each enzyme has a unique shape that fits onto the substrate. As enzymes normally only catalyse one reaction the substrate has to fit in the specific shape (active site) and if it doesn’t fit in (lock and key method) then the enzyme won’t be catalysed. b.) As when the enzyme is denatured it’s special shape is destroyed, thus destroying it’s active site meaning that the substrate wont be able to fit in, therefore not catalysing the enzyme. c.) As enzymes are specific when an enzyme catalyses an enzyme it can be used over and over again as they are not changed during the reaction. 5.) a.) if the concentration of the enzyme is increased the rate f the reaction will increase. This is because there will be more enzymes to help break down the substrate, however when the enzyme reaches it’s optimum it will be equal. b.) if the temperature is decreased it will drop the rate of reaction and slow down the speed of catalysing. c.) if the pH is lowered then the rate of reaction will drop causing the pH to interfere with the bonds holding the enzyme together and denaturing the enzyme. 7.) a.) i) the rate of reaction is increasing at a positive constant correlation, because the increase in temperature is causing the enzymes to move around faster increasing the chance of a collision. ii) the rate suddenly drops after it’s hit the optimum temperature, this is because the bonds holding the enzyme together have broke destroying enzymes special shape. b.) It increases it as it causes the enzymes to move around faster increasing the chance of a collision. c.) the bonds change it’s special shape causing it unable to catalyse substances. d.) A. it could be pepsin in the stomach e.) B, it could be phosphatases f.) it is very narrow.

The Lament for Ignacio Sanchez Mejias Essay Example for Free

The Lament for Ignacio Sanchez Mejias Essay Just like Helen Keller who attempted to attain the summit of her life through her incessant perseverance, I have also been doing my best efforts to achieve constant self-improvement and to work toward my maximum self-actualization. Both Helen Keller and I share one thing in common, that is, we adhere to the same spirit of perseverance and self-perfection. Nevertheless, there is one essential difference. What Helen Keller was trying to do was to overcome her physical predicaments and constraints so that she could behave and do things like a normal person. Being a normal person, I would like to tap my potential to the fullest possible extent so that I can achieve academic and professional excellence necessary for becoming an elite of the emerging young generation. The rapidly growing Chinese economy seems to be providing us with an unprecedented opportunity to our personal fulfillment. Under such circumstances, what we should do is to become fully prepared to embark on our journey of life, to venture into deep waters. As a matter of fact, I have already been making some of the most important preparations for my ambitious undertaking in the future. I completed my undergraduate education from 1998 to 2002 in the specialty of marketing at the Business Administration Department of Institute of XX. Although the Institute is by no means the most prestigious one in China, I have been one of the best students in this Institute. Drawing inspirations from Einstein’s assertion that diligence accounts for 99% of a person’s success, I have endeavored to prove this doctrine through my concrete action. At the very outset of my undergraduate program, I decided that I must make maximum use of all the educational resources available to improve and perfect my knowledge. By the time I graduated, I proved that my undergraduate life was a very rewarding one, embodied in my satisfactory academic performance, important extracurricular activities, a spate of honors and awards, well-developed personal qualities, and recruitment by my Alma Mater. As part of my personal development, my undergraduate career was characterized by constant improvement in academic performance. By the time I became a junior, I was ranked top three in my class. My diligence, sound analytical ability and strong interest in my chosen specialty, all those factors contributed to my sustained scholastic success. Marketing is a subject that encompasses knowledge in economics, management, psychology and other disciplines. This interdisciplinary nature of marketing, plus the challenges of creative thinking that it poses to its learner, helped to strengthen my interest in it as I delved deeper into this subject. As a result, I managed to achieve quite satisfactory scores in all the core courses—Business Psychology, Marketing, International Marketing, Modern Enterprise Management, Public Relations, Market Survey and Prediction, etc. Meanwhile, benefiting from the systematic and rigorous training in economics and management, I have considerably enhanced my analytical skills, which gradually permitted me to grasp the essence of the matter amidst apparently complicated business issues. I also started to reflect on some basis but specific problems in our economy, such as â€Å"Why none of Chinese enterprises have so far failed to enter the world’s top 500? † During my undergraduate program, my academic commitment did not in the least affect my extensive extracurricular involvements. On the contrary, those involvements served to develop my management capacity, interpersonal communication and teamwork. I was a journalist of our Institute’s Journalism Association, reporting on major campus events. I was the chief debater of our Department’s Debate Team and by working closely with my tem members, we won the first prize in our Institute for two consecutive years. My other extracurricular positions included assistant director of the Study Department of the Students Union, director of the Social Practice Department of the Institute’s Students Union, and a member of the Institute’s Students Committee. One thing that should be stressed is that, as director of the Social Practice Department, I successfully launched the final match of Miss Network in XX Province, which was part of XX The match, designed to popularize Internet knowledge and show the charm of the learned women students, produced quite a local sensation. As the main planner of the event, I met and overcame major challenges. I believe I will derive lifelong benefit from this experience. To be engaged in high-level business management has always been my professional objective. As far as I am concerned, this challenging profession is what I am most interested in, one which can allow me to apply my knowledge and expertise to face challenges. With China’s reform toward the market economy, a large number of big enterprises have been created, but over the past two decades, no Chinese enterprise can be found in the world’s top 500. An important factor is that we lack true entrepreneurs and effective ideas of modern strategic marketing and management. This situation calls for well-trained business administrators with international perspectives. An important purpose of your MBA education is to provide systematic theoretical support for solving various business problems while equipping future enterprise administrators with all the necessary managerial skills. In addition, I am deeply fascinated by your MBA program’s competitive and international character. In my proposed program, I will continue to focus on marketing, with special emphasis on studying the advanced marketing strategies and concepts of the world’s top enterprises. It is my conviction that, against the background of economic globalization, an international education can give me far more than the mere knowledge and skills of business administration. As a necessary foundation for my prospective MBA program, I will have accumulated two years of work experience (from 2002 to 2004). Upon completing my undergraduate program, due to my distinguished performance in academic, extracurricular and moral conduct, I was recruited by my Alma Mater to take up a teaching position as a teaching assistant while concomitantly serving as student councilor. For more than one year by now, I have been managing more than 700 students in an entire grade in XX. Although my responsibilities are not those typical of an enterprise, I have derived much pleasure of successful management in ensuring the smooth operation of student life and activities, in addition to promoting my sense of responsibility and managerial expertise. Admittedly, there are important differences between the management of students and the management of employees in an enterprise, I have consciously and creatively applied my knowledge of human resource management that I learned in my management courses. This makes me realize that many theories and approaches of commercial and industrial management can be equally effectively applied to the management of non-profit organizations to improve their operation efficiency. As one of the best-loved XX universities, XX University enjoys a very high prestige for its MBA education. What this University really attracts me is that your university attaches great importance to group research and small-class education whereby students are allowed to collaborate with senior professors to undertake various interesting projects. I believe that this highly interactive and competitive educational model will be very appropriate for me in that it can fully draw out my potential in business management and lay a firm foundation for me to become a business management elite in China. In my proposed study, I will stick to my usual way of self-development—constantly transcending my former self in pursuit of a life of sustained personal development. Just as what Helen Keller said: â€Å"The result of each attempt is a success, and along the ladder pieced together by each individual success, I will ultimately reach the grand altitudes in the deep of the azure clouds—the summit of my hope. †

Vigilant and vigilante

Vigilant and vigilante Civil policing arrangements aim at restoring justice within the society through the use of social justice structures. Capehart and Milovanovic suggest that the restoration of justice requires the reliability of the social structures and institutions within the society to operate efficiently and autonomously (2007). Further from relying on the social justice systems to punish offenders, members of the society are often asked to become vigilant. However, this has resulted into the sprouting of vigilante groups within the society that take upon themselves to deliver justice. Being vigilant refers to being extra careful about ones safety within their immediate environment. This will require the adoption of some safety practices such as walking with a flash light at night or getting home early. By being vigilant, individuals aim at shielding themselves from falling into any imminent danger within their immediate environment. On the other hand, a vigilante is a group composed of individuals that enforce the law on their own accord. Vigilantes seek justice in their self-developed style that is often quite different from the civil laws. Secondly, by being vigilant, an individual does not bestow any powers to punish upon themselves but rather seek to view their immediate environment with more clarity. Vigilantes bestow powers upon themselves by prescribing to other members on the modes of punishment within the society whereby lack of proper social structures could negatively impact on the society. Lastly, vigilantes are a response to a security deficit issue within the society. This deficit results into the unity among the societys members to bridge the justice gap. However, being vigilant is an individual response in an effort to boost ones safety (Capeheart Milovanovic 2007). References Capeheart, L Milovanovic, D 2007, Social Justice: Theories, Iss.

Minimum Wage is The Bare Minimum Essay example -- Argumentative Persua

Minimum Wage: The Bare Minimum "They work hard every day; they stock our store shelves, wash dishes at our restaurants, clean our offices at night, care for our kids during the day...They have in common the minimum wage. And they need a raise, and as you saw, they deserve a raise" (Clinton). President Clinton made this speech on the south lawn of the White House at 10:30 a.m. on the 8th of March 2000. He argued for the minimum wage hike to go into effect. He argued for the population of the United States who worked at the federal minimum wage. But was his argument feasible? Would it be practical to raise the federal minimum wage from its current status of $5.15 an hour, to $6.15 an hour? President Roosevelt instated the first minimum wage on June 25, 1938. It created a law which made it illegal for employers to pay their workers under .25 cents an hour. While this law made it easier for workers, businesses and industries of the time found themselves lower on their supply of money, and higher on demand of workers. Economists predicted that the Great Depression (already in its ninth year) would get worse, and that Roosevelt would lose popularity among his peers. Little did we know Roosevelt lost 80 seats in the house that year, and the Depression worsened (Folsom). Now, the economics of raising the minimum wage has seen many more positive effects, or according to our president and the National Economic Council. "Since the minimum wage was raised in 1996, our economy has created over 10 million new jobs. The unemployment rate is at its lowest point in 30 years" (Clinton). The figures seem to be all in the right to just raise the minimum wage once again. On March 10, 2000 the House passed a m... ...eop.gov.us/2000/3/8/11.text.1 March 8, 2000. Folsom, Burton W.

Profile of Reverand John Hale in Arthur Millers The Crucible :: Essay on The Crucible

The tragic tale of the Salem Witch Trials in Massachusetts was re-written by Arthur Miller in the form of the play â€Å"The Crucible†. The trials have been studied to figure out what really happened, but no one will ever know since it happened decades ago. The play is the closest reenactment we have to help us see how people could have reacted to life. â€Å"The Crucible† shows how using others as a cushion to keep from being punished can go extremely bad. Amidst all the chaos a man by the name Reverend John Hale came to help but ended up with making it a huge amount worse. Mr. Hale as they refer to him in the play, started out as a student at Harvard College and graduated in 1657. Ten years later he was ordained as a minister of the Parish Church in Beverly, Mass on September 20th 1667. He was the first minister of this church from what I read. A few years past and Hale was called to the Village of Salem to rid its streets of witches and witchcraft. His degree and church background make Mr. Hale the best candidate to earn people’s trust, and use it to make the investigation advantage. Mr. Hale’s trip to Salem solely took place so he could just if the girls’ sickness had to do with witchcraft. The manner at which he approached it doomed it from the start, he came in the middle of the chaos with the attitude that he could just fix everything with his books. His stubbornness to look at the situation from another point of view collided with the small town’s fear. This presence seemed to confirm their fear that the devil was already present. Salem was small enough where every one knew everyone and where he or she lived and worked. Word can spread fast and people became determined to stamp out the evil in their town. As the accusations started fueling Hales’ fire to find witchcraft other girls started acting like they were helping Salem. When all the girls started acting like the accused were strangling them and making them do bad things, it just went too far. People started being hung and more of the town started to believe what these young girls had been saying and feeling. Hales was working with the judges and town leaders to see what could be done with the alleged witches and wizards.

Kung Bushman Essay -- essays research papers

The !Kung Bushman Most contemporary foraging groups, such as the !Kung and other Bushman tribes, are viewed as a â€Å"primitive† people. Some have even gone as far to say that they are â€Å"the last representatives of the stone age.† While it is true that these people have the most similar culture to what we believe primitive persons to have had, the analogies they can provide us with the people of the past are very inaccurate. These comparisons are so unrivaled due to factors such as time and the wrong sense of view many people have on them. Another reason that we cannot compare the !Kung of today to the people of the past is because they are now advancing in society with the use of technology. I believe that the !Kung tribe is not comparable to the early people of their culture and that they are just the same as us minus our technology, which in no way makes them ‘primitive’ people. First of all, every culture varies in traditions over time. According to Shostak, it is t rue that the !Kung people still have traditions that have been passed down for hundreds of generations such as their poison arrows, their trance ritual, their wide knowledge of over five hundred species of plants and animals—knowing which are edible, harmful, cosmetic, and medical. Who are we to say that these traditions have not been altered in the past ten thousand years? Howell declares that the !Kung were a very studied group including their language, culture, and economic organization. Although they have been extensively studied, Howell also proclaims, â€Å"It is surely illegitimate to use them as though they are the prototypical hunter-gatherers, knowledge of whom tells us all we need to know in order to apply the ethnographic analogy to models of prehistoric life.† Wild, maniac, unsophisticated, uneducated, vulgar†¦these are all words that come to mind when I think of prehistoric or primitive. Obviously the !Kung tribe have grown with the rest of society. How are we to say what the differences of prehistoric life was to the modern day !Kung tribes? Human error would play a huge role in our â€Å"assumptions† of the !Kung. For example, we might turn around to be just as wrong as the article of the Nacirema. Obviously, there is already a misconception about the bushman. For example, in McNeil’s essay, he comments on how a woman was speaking to a bushman and demanded to see one. When he explained ... ...† The bushman are pretending to be people they are not, giving the tourists what they want. This also gives tourists the wrong impression and significantly aids in the ignorance of the !Kung. This would be devastating to their culture. Culture, after all, is associated with the changes a society goes through over time. If these ‘prisons’ were to be set up, the culture would be forced and therefore in no way a comparison to early persons. Obviously, the !Kung have a very unique culture compared to how we live our lives. They in no way, however, represent what the culture of early persons to have. They have their own culture, unique to their society, and like ours†¦ever changing. What most people consider â€Å"primitive† is an ethnocentric remark to the difference of their culture to ours. The !Kung just have their very own technology, which is very efficient seeing that they survived this long. Due to time, ignorance, and the bushman’s leanin g towards our methods, they in no way can be compared to early people by means of their culture. The !Kung Bushmen are living their own lives now, in the present, therefore they can be in no way considered ‘people of the past.’ Word Count: 1024

Concepts, Control and Choice Between the Matrix Trilogy and Plato’s Allegory of the Cave

The human mind may be seen as a sophisticated computing machine which has for its object of thought that which we call reality. In a certain sense, scientific knowledge and technological developments continuously define and redefine our sense of what is real. Questions concerning reality are questions that are paradigmatically philosophical. A paradigmatically philosophical question is a question that is both familiar and strange. This familiarity and strangeness of reality manifests itself when we try to ask ourselves the question: What is reality? On a preliminary note, both The Matrix Trilogy and Plato’s Allegory of the Cave present us with fundamental questions concerning reality and knowledge. Moreover, both The Matrix and Plato present us with questions concerning a very important characterization of the human being: our capacity for choice which is built upon the concepts of rationality and autonomy. As rational and autonomous beings, we are responsible for the choices that we make. In 514a of Plato’s work called Republic, he offers the Allegory of the Cave as an analogy for the educational progress or enlightenment of the soul. In Plato’s theory of the Divided Line, he uses the sun as a metaphor for the Form of the Good, which for him, is the proper object of thought. It is important to note that Plato assigns an ontological status to the Forms. The Forms are real, so to speak. In the allegory of the cave, he uses a surrogate metaphor for the sun: the fire within the cave. The main thrust of the Allegory of the Cave is to contrast life within the cave with the life outside of it. The cave, in Plato’s work, is a prison wherein the individuals dwell in the world of semblances. Inside the cave, the prisoners only see shadows of objects produced by the light coming from the fire. Plato uses the object-image metaphor to illustrate this point. What we may thus infer is that knowledge and reality, in Plato’s account of them in the Allegory of the Cave, comes in degrees. Regarding this particular differentiation between object and image and the real from a mere semblance or copy, Cornford writes that Plato views â€Å"†¦a world of intelligible Forms separate from the things our senses perceive† (2). In effect, Plato envisions reality as that which is absolute and accessible only through thought in contrast with mere semblances or copies that we find in the sensible world. Whereas Plato considers reality as absolute, the Matrix Trilogy depicts not just a reality but ‘realities’ which overlap each other. Morpheus presents Neo with a dilemma when the latter has to make a choice between which pill to take. The evidence of the aforementioned necessity to choose is evident as Morpheus states that â€Å"no one can be told what the Matrix is (since its existence is something that one ought) to see for one’s self†. In this sense, the discovery of reality is to be understood as an act which involves the reacquisition of a new perspective in which one may understand reality per se. According to Irwin, the similitude of Plato’s conception of the Forms in relation to the conception of reality as presented within the aforementioned text is evident if one considers that â€Å"as with the Forms, it is not a literal ‘seeing’ (which is involved) but a direct knowing that brings understanding of the Matrix† (14). In the movie, the red pill stands for ‘truth’ which eventually allows Neo to see behind the deceiving reality produced by the matrix. In very important respects, the red pill also stands for the biblical interpretation associated with the Tree of Knowledge from the Garden of Eden. In the film, the red pill induced the discovery that the world in which Neo lives is not real but a mere virtual reality (Lloyd 32). The fact of the matter is that Neo’s body is stored in a body farm with his mind plugged into the matrix. It is not difficult to see the apparent similarity with this state of affairs with Plato’s Allegory of the Cave. In effect, we may say that Neo and the prisoners in the cave are in a state of illusion. Both Neo and the prisoners in the cave are presented with two options: to remain in the state of illusion or to liberate themselves from the virtual reality of the matrix or the shadows in the cave. The meaning of human life then, its purpose and moral integrity in a physical or bodily existence in the context of The Matrix is to be found in human beings’ opposition to the illusions produced by the Matrix or in a more academic terminology, ‘technological modernity’ and by restoring the natural world. In today’s world, there is a clamor for a paradigm shift in terms of adapting to the demands of modernity. Such a shift is considered by Beck as necessary when he writes that: A new kind of capitalism, a new kind of economy, a new kind of global order, a new kind of politics and law, a new kind of society and personal life are in the making which both separately and in context are clearly distinct from earlier phases of social evolution (81). In line with this, it is important to note Agent Smith’s initial explanation as to the creation of the Matrix. According to Agent Smith, the Matrix was â€Å"designed to be a perfect human world where none suffered†. The result of the design, however, remained as an ideal. Agent Smith noted that the reason for this lies in the imperfection of the programming language used to depict that perfect world. He notes, â€Å"I believe that as species human beings define their reality through misery and suffering. The perfect world was a dream that your primitive cerebrum kept trying to wake up from†. Questions concerning the meaning and purpose of human life are further explored on Matrix Reloaded and Matrix Revolution. They provide more complicated and dialectical approach of what it means for a human being to live in a technological world. The aforementioned complexity may be inferred from comparing the possibilities that are evident in the presentation of the worlds in the three movies. It is important to note that in the first movie, the matrix and the machine from which it gets its sustenance only seems to provide less complicated and normative possibilities evident in its ‘either-or’ presentation. It is at this particular aspect point where one may say that Reloaded and Revolution provide a more appropriate construal of the human condition. These two were able to explore not only the diametrically opposing views on technology and human society but also their complex interdependence. It is not difficult to see that the moral dilemma posed by Reloaded and Revolution then, is not simply to escape from our technological milieu, but to discover and rediscover what it is that enables us to be and to remain ‘human’ within such a world. Furthermore, the narrative suggests that the threat of a nihilistic instrumentalism is to be found, not simply in the external world of technological devices and systems prima facie, but in that moral and metaphysical trajectory underlying a mechanistic technoscience. The urgent task that it points to is thus to contest the nihilism of the Baconian dream and to recover those deeper sources that can sustain moral and spiritual experience and relationship even within a highly technologically advanced world. Another important aspect that ought to be given emphasis is the ‘divide’ existing behind those who know the truth [or reality] and those who do not know. Zion, the last bastion of humanity, represents that which is real. Why is it important to point out the so called divide? The answer is rather obvious. This particular aspect further generates systems of power and power relations. In a certain sense, it maintains political power. Whoever creates the divide, the fake choice, is placed at the point of authority and ultimate control. Withholding the knowledge of one world from another is simply a tool of this control – and the Plato’s Cave, so often referred to in discussions on The Matrix, does not necessarily have to refer to Zion alone. It represents any society where the knowledge is withheld from both sides of the divide, and where the self-examination of each group is discouraged of stepping over into examination of the whole system. Mindful of the points of convergence between the Matrix Trilogy and Plato’s Allegory of the Cave in terms of their themes and philosophical underpinnings, we may safely add that both of them employed, in one way or another, the use of myths and metaphors in terms accounting for the concept of reality. If we are to characterize the ancient mind, we may say that it thinks in terms of metaphors. Metaphorical thinking is still one of the ways in and through which we try to explain and appropriate for ourselves various phenomena. One may take the time to consider how, for instance, we used to explain to ourselves that ‘the universe is a machine’. This was the metaphor during the time of Leibniz which continued to flourish in the advent of scientific reductionism. There remains, however, a significant difference in the Matrix Trilogy and Plato’s Allegory of the Cave. Whereas, the path to Zion, the representation of that which is real requires Neo and the others to rebel against the matrix for them to be able to liberate themselves, the path to Plato’s Form of the Good, that which is real, requires introspection and a life of contemplation. This is because Plato is primarily concerned with questions of ontology than questions of politics or even ethics. In the case of the Allegory of the Cave, Plato seeks to explain the nature of reality and knowledge. He is concerned with the liberation of the mind from ignorance and dogmatism. Human beings’ capacity for reason is what distinguishes them from other forms of life in the universe. Rationality is an excellence of the noble soul.
