(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?

(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)

(04.01 MC) Among a migrating species of fish, one individual migrates further than any other in its population. As a result, the fish develops stronger swimming muscles than any other individual in its population, allowing it to catch more prey. Will the fish’s offspring be favored by natural selection? Why or why not? (3 points)
