(04.05 MC) A group of scientists wants to test the effects of increased water temperatures on a population of halibut. What result from this experiment would show natural selection in progress? (3 points)

(04.03 LC) Which of the definitions below best defines anthropogenic? (3 points)

(04.06 LC) Where would the highest density of mangrove forests be found? (3 points)

(04.03 MC) Between 1932 and 1968, a chemical factory in Japan released mercury-laden wastewater into Minamata Bay. The mercury was modified to methylmercury by bacteria living in bottom sediments. This resulted in severe mercury poisoning in over 2,000 people. Since people don’t eat bottom sediments, what is the best explanation for how toxic levels of mercury ended up in affected people? (3 points)

(04.06 LC) Mangrove swamps serve as prime nursery grounds for young marine animals. Which population of young animals would most likely live there? (3 points)

(04.06 MC) What prediction can be made about how the distribution of coral reef populations would be affected if the oceans in which they live were to experience significantly more cloudiness of the water? (3 points)

(04.06 MC) The histogram shows the worldwide population densities of killer whales, or orcas, distributed by latitude. According to the graph, how does the population density of killer whales vary around the globe? (3 points) © 2016 NOAA

(04.04 LC) What would be the effect on a sea turtle population after a disease has impacted a population? (3 points)

(04.03 MC) The blue lobster results from a rare genetic mutation. Imagine that this mutation makes the lobsters more attractive to lobsters of the opposite sex, and thus more likely to breed. How would you describe this mutation? (3 points)

(06.03 LC) Is oil a renewable or nonrenewable resource? Why? (3 points)
