(01.01 MC) A marine scientist is studying photosynthetic organisms, which use sunlight to produce their own food. She observes that they tend to populate shallower ocean depths. She concludes that photosynthetic organisms can only live in areas of low pressure. Why is this an invalid scientific conclusion? (3 points)

(01.01 LC) Why is pseudoscience not considered real science? (3 points)

(01.04 MC) Much of life on Earth is based in aquatic biomes. What property of water allows life to survive in liquid water? (3 points)

(02.01 MC) The theory of plate tectonics was developed with the contribution of scientists from many different disciplines. Which of the following is a contribution from geophysicists? (3 points)

(03.01 MC) Over the last few decades, scientists have noticed that lobsters, which obtain heat from the environment rather than generating it themselves, are moving north at a rate of six kilometers per year. What is the best explanation based on these observations? (3 points)

(01.03 MC) In order to simulate bathypelagic zone conditions in a model aquarium design, what light and pressure conditions would be required? (3 points)

(02.02 HC) In 2014, the European Space Agency’s Rosetta mission landed on comet 67P/Churyumov-Gerasimenko. The spacecraft detected the presence of water ice on the comet. Does this finding allow the outside-in model to be elevated to a scientific theory? Why or why not? (3 points)

(01.03 LC) Which ocean zone receives the most of sunlight? (3 points)

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

(03.02 HC) A group of scientists is developing a new chemical compound. They want to test its effects on an aquatic ecosystem using a nearby ocean bay. They enclose a region of a bay with an insulated covering to create an isolated system in which to do their experiment. Predict what would happen to living organisms in this isolated experimental system. (3 points)
