(04.02 HC) Consider the production of genetically modified (GM) fish for food. While GM fish can improve nutrition and have economic benefits, people have expressed concerns. Evaluate the arguments below and consider which one is the most effective in addressing concerns that GM fish may harm wild populations if they escape into the wild. (3 points)

(04.02 MC) A scientist wants to improve the effectiveness of a technique in which bacteria are used to consume the oil. Where should the scientist add the bacteria to maximize their effectiveness? (3 points)

(04.03 MC) What relationship exists between the densities of predator and prey populations, according to the graph “Population Change of a Predator and its Prey Over Time”? (3 points) © 2016 FLVS

(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) © 2016 FLVS

(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. Produce a hypothesis accounting for the change in light brown versus dark brown sea lions.

(04.02 MC) Marine biotechnology can be used for cleaning oil spills through biodegradation. What animals do you think would be most directly affected by this? (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 oceanic salinity (35 practical salinity unit ). After a few days, she 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) © Public domain

(06.03 MC) Geothermal energy can be found almost anywhere on Earth but generators that are used to convert the resource into energy are expensive to build. Which of the following characteristics of renewable energy makes it so important that a community should invest in developing its geothermal activity? (3 points)

(06.03 LC) Which of the following has a positive effect by acting as an artificial reef in some areas? (3 points)
