(04.05 MC) In the Galapagos islands, the weather causes a variation in algae growth year to year. Marine iguanas eat the algae, and during the years with more algae growth, the marine iguanas lay more eggs. What is the benefit of this overproduction of eggs? (3 points)

(04.05 LC) What is overproduction? (3 points)

(06.03 LC) How can we, as a society of consumers, help fish stay a renewable resource? (3 points)

(04.03 HC) A doctoral student is studying the genetic makeup of a species of jellyfish that occurs at low, middle, and high latitude regions of the Pacific Ocean. On an oceanographic expedition, she collects specimens of the jellyfish throughout its range. Upon returning to the laboratory at the university, an assistant places all of the jellyfish in an aquarium with an average temperature of approximately 20°C. After a few days, he notes that almost two-thirds of the jellyfish have died. Using the figure below, how would you explain which jellyfish likely make up the bulk of the survivors and what the mistake was? (3 points) © 2016 CC-BY-SA

(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)

(04.05 MC) The fur coat of California sea lions can be different shades of brown due to genetic variation. Suppose that the frequency of each fur color changed in a population as shown on the graph below. How will the population change from 2010 to 2020 if light brown sea lions are more reproductively successful than dark brown sea lions in the next decade? (3 points)

(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 a pathogen? (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)
