(05.06 MC) A Response Options Calculator (ROC) can be used when responding to an oil spill to help predict how the oil will change over time and determine which methods can be best used to clean it. What is the benefit of this type of tool? (3 points)

(05.06 MC) An oil spill happened at the Wild Harbor salt marsh on Cape Cod, Massachusetts in 1969. The oil has persisted in the ground since then. How is the green crab used as evidence for the idea that oil still exists in the lower layers of the soil? (3 points)

(05.01 MC) Which scenario describes a way that an abiotic factor can impact a marine system? (3 points)

(06.04 HC) As a fishery scientist, you notice that very few cod fish have been caught in the past year. You still see very young and larval cod fish in the water, but very few adults. Explain three actions you would include in a plan for the recovery of the cod fish. Explain how you would need to address the Tragedy of the Commons to encourage those using the resource to use it appropriately. (5 points)

(04.04 MC) Juvenile Red Snapper are found close to shore, while adults live and spawn in deeper water. An oil rig started seeping oil close to shore near the juvenile population of Red Snapper. What do you predict would be the biggest impact on this population due to the oil leakage? (3 points)
