1. Identify and explain the ONE specific branch of biology involved in the article - it will be one of the branches listed beside the article title. Support your answer by using specific examples from the article to demonstrate how it relates to that branch. There should be a clear relationship between the branch you chose and the article in your explanation. Explain in your own words without having to quote directly from the article. (At least 3 sentences – 3 points)
A specific branch used in this article was health and medicine. This can be shown where the article talks about the different effects that perfluoroalkyl substances (PFAs) can have on our health. Among those included were the production of cancerous cells and a change in our genetic information. Both of the effects mentioned are harmful to us and can damage the health of a human and animal. Another place where the article has to do with health and medicine is where it talks about where they saw the PFAs building up in polar bears. Although the liver normally regulates PFAs, many were found in the brain, which was not n...
Many stories people read are written for the express purpose of entertainment and sometimes even to persuade, but few are written to teach a moral. The story “A Fable with Slips of White Paper Spilling From The Pockets” written by Kevin Brockmeier does just that. Although relatively short, the story is filled with words of wisdom and life lessons that are meant to instill a sense of selflessness. The story is about a man who finds God’s overcoat from which he finds prayers from the people he encounters. Kevin Brockmeier makes exceptional use of magic realism and symbolism to teach a moral lesson.
1. Discuss the significant of each of the following citations. Provide several examples that support each quote.
Answer the following questions with information you learned in the document , your book, and through Internet research:
4. Shows the similarities or differences between the different sources in ways that make the paper as informative as possible;
The premise of Theo Colborns’ research was to find the connection between the rising incidences of cancer and environmental contamination in the Great Lakes region. However, during field and laboratory studies, Colborn discovered that there was no direct link between the contamination and cancer. However, Colborn did find reoccurring patterns of abnormal behavior and deformed offspring amongst the wildlife populations in the Great Lakes region. Elevated levels of polychlorinated biphenls (PCBs), pesticides dieldrin, DDT, lindane and chlordane were found during tissue analysis of the wildlife in the Great Lakes region (Colborn et. Al 1996). These elevated levels were found in offspring of the wildlife who appeared to be healthy. This supported Colborns’ hypothesis that these contaminations disrupt hormones produced by the endocrine system during growth and development, which will then cause physical and behavioral abnormalities in the fetus.
Paragraph two: Explain the historical background that led to the event, or detail the life of the person you are researching.

Humans are among the many terrestrial mammals affected by the endocrine-disrupting capabilities of bisphenol A. The majority of human exposure comes from consumption of BPA from food products packaged in polycarbonate plastics (Crain et al., 2007). Laboratory studies done on mice indicate that exposure to high concentrations of BPA can cause pregnancy complications, reproductive organ defects, obesity, early puberty, and cancer (reviewed by Flint et al., 2012).
Choose one of the following topics and write a well-organized essay with evidence supporting the statements you set forth. Your response should be two pages, double spaced with a 12 font in Times New Roman:
Some arguments presented in the article were quite logical, but other, e.g. A.M.C., sounded rather lame. Handpicking organisms with certain traits is not the best approach to a logical statement, or even a scientific study, for that matter. Humans use generalizations. This helped us survive iver millenia. So, when we want to compare, say, two species, we use specimens- organisms that possess traits which are considered normal for its species. For us, a specimen would be an adult, sane human. In that case, the result would be quite different.
Evidence provided to support these claims of human and wildlife harm is largely from laboratory studies in which large doses are fed to test animals, usually rats or mice, and field studies of wildlife species that have been exposed to the chemicals mentioned above. In laboratory studies, high doses are required to give weak hormone activity. These doses are not likely to be encountered in the environment. However the process of bioaccumulation can result in top-level predators such as humans to have contaminants at levels many million times greater than the environmental background levels (Guilette 1994). In field studies, toxicity caused by endocrine disruption has been associated with the presence of certain pollutants. Findings from such studies include: reproductive disruption in starfish due to PCBs, bird eggshell thinning due to DDT, reproductive failure in mink, small penises in alligators due to DDT and dicofol (Guillette 1994, Colburn et al 1996). In addition, a variety of reproductive problems in many other species are claimed to be associated with environmental contamination although the specific causative agents have not been determined. One recent discovery that complicates the situation is that there are many naturally occurring "phytoestrogens", or chemicals of plant origin that exhibit weak estrogenic properties.
Summarize what you think is the most important information in the article. You should include details and examples from the article. Also, identify any inferences or conclusions that this article makes.

In addition to their many adverse effects on the human body, flame retardants also represent a hazard to the environment. They have similar effects on other animals as they do on humans. Even after certain types of flame retardants’ production was stopped after the discovery of their dangerous effects, they are still being detected in the environment, and are therefore still disturbing the ecosystem.
