(01.02 MC) A deep sea robot is sent to the bottom of the ocean. What will it most likely observe, in terms of the numbers of photosynthetic organisms and light conditions? (3 points)

(02.02 MC) When the Earth’s continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation? (3 points)

(01.04 LC) What property of water allows fish to survive in a lake that is frozen over? (3 points)

(01.01 MC) A Spanish scientist observes that salmon produce more eggs when grown in warmer aquariums. He asks his colleague in the United States to conduct the same experiment using the same aquarium equipment. Should he expect the results to be similar? (3 points)

(01.02 HC) Scientists have believed for many years that marine temperatures drop as ocean depth increases. What experimental method would best test this hypothesis, and why? (3 points)

(01.02 MC) A submarine robot is operating near the ocean floor. What pressure and temperature data will it most likely record? (3 points)

(01.01 MC) A professor researching seaweed at a laboratory in the United States has been offered a position at a Chinese university. She needs to decide whether to move her experiments to China or whether to start the experiments over. Would it be appropriate scientific methodology to transport her experiments to China and continue them there? (3 points)

(01.03 HC) A scientist discovers a new species of marine bacteria that do not require oxygen to survive. In fact, dissolved oxygen in the water is actually toxic to these bacteria. Predict what region of the ocean this species would most likely inhabit, and select the best explanation. (3 points)

(01.04 MC) Sascha notices that steam appears from water only when the water is very hot. What property of water explains this observation? (3 points)

(01.03 HC) Atlantic halibut is a species of flatfish that uses gills to extract dissolved gases from water for cellular respiration. During a storm, a population of halibut is carried down into a deeper layer of the ocean. Predict whether this population would most likely thrive or die, and select the best explanation. (3 points)
