Evolution - Lab Report Example The major tool used in this biological experiment was a specially programmed computer application (automated) that enables adjustment of variables from default figures and when run, accurate results on the changes that has occurred in the biological structures of living organisms were shown. These results are therefore used to justify the hypothesis. In the first experiment, when the independent variable (precipitation) is adjusted to higher levels, the birds evolve smaller beaks. This is because when precipitation is high then the seeds become softer and the birds slowly adjust to the changes of nature until the fully adapt. On the other hand when precipitation is low, the seeds become harder and the need for additional force to crack the seeds arise and based similar principle; the birds evolve stronger and larger beaks over time (Sober, 2008). This adjustment may not favor some birds as the adaptation and evolution process is gradual and therefore may lead to death of individuals that are unable to adjust effectively to the changes of nature. Natural selection can influence variation of a trait in a population in three major forms namely; diversifying, directional and stabilizing forms (Sober, 2008). In the second experiment, it is clearly evident that changes in the environmental conditions favors the individuals with specific phenotypes. When important parameters that influence natural selection such as precipitation is manipulated (adjusted to 50cm/year and 0cm/year on Wallace Island and Darwin Island respectively), it is noted with great significance that only a few individuals are able to survive and continue reproducing in an environment with low precipitation. This is because of the variation in biological and environmental factors that are very significant for natural selection. Therefore for a period of 300 years, these changes will influence the evolution of Finch beaks and in turn affect their population. This fact can be justified by the graphs

Compare the differences between China and America on using of media Essay

Compare the differences between China and America on using of media entertainment and media effect on individual - Essay Example To this end, the paper will critique the fundamental elements and aspects of culture and provide a review of how they define dominant trends and patterns in the society. The paper will undertake a comparative analysis and review of culture and how it shapes entertainment in two countries - China and the United States of America. To this end, there will be a critical review of various aspects of culture and the media in these two countries. Fundamentally, the media captures contemporary issues and matters in a given society and community (Cowans, 2000). This is because the media often focuses on addressing dominant matters and situations as and when they unfold in the time in question. Thus, culture is central and important in defining what the mainstream mindset and expectations of the people is and what unconventional conflicts and issues come up to form an appropriate storyline for the media. "Culture provides a kaleidoscope within which human emotions are defined" (Rohn, 2009: p232). This implies that culture defines what is to be done in every stage in the human life from birth, puberty, adulthood, old age to death (Rohn, 2009). As such, the definitions of happiness and sadness is dictated by what the dominant culture values and identifies to be important. Typically, the media presents issues and matters that challenges the status quo and this is often a situation that is uncommon or unusual. This is because members of the society and audiences around the world will prefer to view issues and matters that do not really seem to be conventional or in line with the dominant practices and views of the society. Culture has a strong linkage to the media and the media has two main issues that converge to create this connection: dominant conflicts in the culture and new technology (Marsh, 2012). Marsh argues that in the normal sense, audiences to the media often seek to view things that are not in sync with the dominant
