BIOL107 FINAL EXAM (MODULE 1,5,2.3,4.1,6.1,6.2,8.4,10.2) WITH LATEST QUESTIONS AND CORRECT ANSWERS RATED A+ You attend a community meeting at which people are discussing the possibility of approving a largescale wind power project that would allow developers to install six large wind turbines on the crest of a hill in a rural, wooded part of the county, and this installation would be enough to supply the nearby community with electricity. Answer the following questions based on this scenario. A final speaker acknowledges that wind turbines have problems but suggests that the advantages outweigh the disadvantages. The area suffers from acid rain and particulate air pollution that is linked to a nearby coal-fired power plant. These wind turbines will decrease the amount of coal that must be burned, and this will reduce air pollution. Though some animals may unfortunately be killed, the wind instillation will help the ecosystem as a whole, he argues, making it healthier for the plants and animals that live there. His argumen - ANS-both an anthropocentric and ecocentric A good example of sustainability is: - ANS-purchasing products in packaging that can be recycled, riding a bicycle to work, using solar panels to generate electricity, limiting commercial fishing to amounts that allow the fish population to repopulate. **ALL OF THE ABOVE** A graph that shows the strength of an effect of a substance at different doses is a(n) _____ curve. - ANSdose-response A new drug has been developed to inhibit the replication of HIV, the retrovirus that causes AIDS. In studies using mice as a model organism, the drug showed amazing results: 60% of infected mice who received the drug did not go on to develop AIDS. This drug has the potential to help eradicate AIDS in humans, but it is unknown what possible side effects exist. As an FDA regulator, what would you see as the pros and cons of applying the precautionary principle to this new drug? - ANS-As an FDA regulator, I would want to see this drug go to drug trial prior to its widespread availability, applying the precautionary principle. The drawback, or con, of this situation would be the time that it would take for this drug to be approved and the apparent benefits coming out of animal testing. This could take years, and lives could be lost in the mean time. *these are my own words* An example of applied science is: - ANS-designing a solar panel for increased efficiency Which statement is TRUE of conventional natural gas deposits? - ANS-they can be found in deposits that contain no oil Which statement is TRUE regarding the greenhouse effect? - ANS-Increased levels of human-produced carbon dioxide have enhanced the greenhouse effect Which type of fuel is composed of hydrocarbons? - ANS-natural gas, coal, wood, oil *All of these answer choices are correct* A substance that causes damage when it contacts, or enters, the body is called: - ANS-toxic As you are painting your room, you develop a headache from the paint fumes. You are experiencing a(n) _____ effect. - ANS-acute Based on the precautionary principle, what is TRUE? - ANS-Harmful products are prevented from reaching store shelves. *Match the term with the statement that it best exemplifies* biomagnification - ANS-R. the increased levels of fat-soluble substances in the tissue of predatory animals that have consumed organisms that have taken up toxins Blogs, websites, and news shows that provide additional commentary on reports from the popular press are considered _____ sources. - ANS-tertiary Consumer groups called for a ban on BPA, a chemical known to be an endocrine disruptor, suggesting that financial interests from companies that profit from BPA-made products cause them to suppress data that might show BPA to be harmful. Which common logical fallacy is at work here? - ANS-ad hominem attack *Match each term to the statement that it best exemplifies* environmental science - ANS-L. an interdisciplinary field of research that draws on the natural and social sciences and the humanities in order to understand the natural world and our relationship to it Environmental science relies or draws on: - ANS-natural sciences such as ecology, humanities such as literature, social sciences such as anthropology, applied sciences such as engineering. *All of these choices are related to environmental science* How is anthropogenic climate change different from the climate change experienced by the Greenland Vikings? - ANS-It is caused by human actions If antibiotics are used frequently over a short period of time, bacteria can become resistant to those antibiotics and harder to treat. This scenario is an example of: - ANS-tragedy of the commons In biomimicry, scientists use nature as a model, _____, and measure. - ANS-mentor Individuals react differently to toxin exposures. Which factor could affect an individual's reaction to toxin exposure? - ANS-dose of toxin, age of the individual, route of exposure (inhalation or skin contact), genetics of the individual *All of these answers are correct* Ocean tuna eat smaller fish that consume material containing mercury. Mercury is a persistent toxin that builds up in higher amounts in the bodies of fish. The mercury in the smaller fish accumulates in the ocean tuna in higher amounts. When we consume tuna, the mercury in the tuna can accumulate in our bodies in higher amounts. This phenomenon is called: - ANS-biomagnification Use the following scenario to answer the question(s) below. You attend a community meeting at which people are discussing the possibility of approving a largescale wind power project that would allow developers to install six large wind turbines on the crest of a hill in a rural, wooded part of the county, and this installation would be enough to supply the nearby community with electricity. Answer the following questions based on this scenario. One developer who recently bought land in the area near the proposed site and who has plans to develop a new subdivision complains that the wind turbines will be a noisy eyesore, and he does not want the project approved. He worries that the installation will drive down property values and make prospective buyers wary about buying his subdivision lots. What worldview do his comments suggest he has? - ANS-antropocentric Potential trade-offs to reforestation efforts include: - ANS-less land for agriculture, water shortages, high cost, fragmentation of habitats *All of these answers are potential trade-offs to reforestation efforts* Scientists are studying the effects of two chemicals on high blood pressure. When chemical A is used, blood pressure decreases by 20%. When chemical B is used, blood pressure decreases by 40%. When both chemical A and chemical B are used, blood pressure dec - ANS-antagonistic *Match the term with the statement that it best exemplifies* solubility - ANS-G. ability of a toxin to dissolve in gas or liquid, particularly water The Centers for Disease Control and Prevention declared that medical intervention is needed when concentrations of lead in the blood are at or above 5 micrograms per deciliter (μg/dL). In Flint, most children with elevated blood levels of lead had values between _____ μg/dL. - ANS-5 and 9 The claims that a chemical either must be completely avoided or it is totally safe for everyone are which type of common logical fallacy? - ANS-false dichotomy The lead found in the water in Flint, Michigan, is what type of toxic chemical? - ANS-poison The time it takes for a substance to decay in the environment is called: - ANS-persistence *Match each term to the statement that it best exemplifies* triple bottom line - ANS-I. the combination of the environmental, social, and economic impacts of our choices What does an environment include? - ANS-An environment includes the living and nonliving things that an organism interacts with, or the things that have an effect on it. *my own words*
