Antibiotic Resistance Essays - Evolutionary Biology,

Antibiotic Resistance Darwin's theory of evolution can be explained like this; the environment acts as a selective agent, weeding out organisms less able to survive. Darwin described natural selection as a process in which organisms become better adapted to their environment. The organisms that evolved with beneficial variations are more likely to survive and reproduce, they pass on the favorable genetic material. Over time, the genetic composition of the species may become better able to escape being eaten or to capture prey. Do to such high demand for antibiotics around the world people have created their own antibiotic resistance and became immune to antibodies. At least half of the human use of antibiotics in the United States is unnecessary or inappropriate. For example, a patient demanding antibiotics for an illness that doesn't require them leads to a lot of unneeded drugs. Either the antibiotics are not needed at all, or it's the wrong dosage prescribed, or the wrong duration. More than 50 million pounds of antibiotics are produced in the United States every year. Forty percent of that total is given to animals, mostly to promote growth rather than treat disease. Antibiotic use is also rampant in agriculture. Drugs are sprayed on to fruit trees to prevent bacterial infections. The bad thing is, is that these bugs are developing a resistance to these drugs that once destroyed them. We are experiencing an alarming resurgence of common but no longer curable infections from bugs that developed resistance. This is by being too much involved with taking antibiotics for every little sickness and all other things that would require antibiotics. Another thing that would pose as a problem is the way that bacteria would evolve and adapt to our antibiotics. Darwin's theory can be related to antibiotic resistance in many ways. Through the years of using antibiotics against bacteria, we have seen that they usually get the job done. But as time progresses, so do the bacteria. As fast as we are producing the antibodies, the bacteria are adjusting to them faster. With all the antibiotics that humans take in, their bodies are becoming immune to the effects. Which is like Darwin's theory of natural selection; selecting out the organisms that cant adapt or adjust to the environment around them.

Free Essays on What Is Political Science

political science The study of government, political processes, institutions, and behavior. Government and politics have been studied and commented on since the time of the ancient Greeks. However, it is only with the general systematization of the social sciences in the last 100 years that political science has emerged as a separate definable area of study. Political science is commonly divided into a number of subfields, the most prominent being political theory, national government, comparative government, international relations, and special areas shared with other social sciences such as sociology, psychology, and economics. In practice, these subfields overlap. Political theory encompasses the following related areas: the study of the history of political thought; the examination of questions of justice and morality in the context of the relationships between individuals, society, and government; and the formulation of conceptual approaches and models in order to understand more fully political and governmental processes. The study of national government focuses on the political system of the researcher's particular country, including the legal and constitutional arrangements and institutions; the interaction of various levels of government, other social and political groups, and the individual; and proposals for improving governmental structure and policy. Comparative government covers many of the same subjects but from the perspective of parallel political behavior in several countries, regions, or time periods. International relations deals both with the more traditional areas of study, such as international law, diplomacy, political economy, international organizations, and other forms of contact between nation states, and with the development of general, scientific models of international political systems. None of the political science subfields can be clearly separated. All of them, for example, deal with questions clos...

Ancient Greek Athletics of Pentathlon Essay Example | Topics and Well Written Essays - 1250 words

Ancient Greek Athletics of Pentathlon - Essay Example As the Greek term pentathlon suggests, in the Ancient Greek pentathlon, athletes competed in five items which included a wrestling competition, a sprint item or a race the length of the stadium, long jump, discus throw, and javelin throw. Some significant questions arise in this background. Why were there no individual events for discus, javelin and long jump in the ancient Olympics Why were these events limited to the combined pentathlon event The answers to these questions lead one to the ultimate conclusion that the different items of the pentathlon were not just some sports events, but rather they are very distinctly linked to the social and cultural systems of the Greeks which gave primary importance to the development and the progress of the citizens. All these competition items were opportunity for the Greek valiant men for expression of their sheer quality. This Ancient Greek athletics were very much part of the Greek tradition and through the epic tradition of the Greeks one can find examples of their pertinent importance in their culture. The real importance of these athletic competitions may be measured on the basis of the question of prestige and the glorification of the athletes in the pentathlon. To the mighty Greeks, who was the prime most race of the world in their age, pentathlon presented with an opportunity to express their greatness as a prestigious groups or a particularly important people. It may be argued that while these competitions provided the Greeks with an opportunity to achieve personal glory and might in a culture which ranked excellence of physical strength and valor, there has been greater value to these athletic items in the preservation of the state's interest which is, of course, the well being and advancement of the citizens who are benefited from the physical effort they invest in pentathlon. However, the more significant value of the pentathlon was that the events aimed at the overall progress of the Greeks contributing to its rich cultural and social systems. Pentathlon consists of five items - Discuss (Diskos), Javelin (Halma), Long Jump (Akon), Running (Stadion) and Wrestling (Pale). These items were linked to the progress of the individual and they are related with the social and cultural systems which emphasized the glorification of individuals in every sphere. Thus, the events were performed together rather than individually. "The Olympic games were not proving grounds for real combat The games were more symbolic, religious, and entertaining. Unlike hoplite, team-style warfare, the ancient Olympics were individual sports which allowed an individual Greek to win glory." (Gill). There are myths about the pentathlon which establish Jason, the leader of the Argonauts, as the originator of pentathlon. In the year 708 BCE, pentathlon became an Olympic event. It was in the 18th Olympiad that the pentathlon was introduced. The events in pentathlon ensured the developments of the chief skills of the individual which make one national hero and the example of Odysseus who was successful in every event in the pentathlon proves this social as well as cultural focus of the pentathlon. The role of pentathlon in arousing the national pride and prestige of the Greeks has its testimonies in the epics of the Greeks. Thus, in the Homer's Odyssey, one finds evidence of pentathlon
