(01.01 MC) A scientist studying algae growth in a coral reef observed that the presence of a certain type of zooplankton inhibited the algae growth. The scientist hypothesized that the zooplanton was eating the algae. Which experimental design would best test this hypothesis? (3 points)

(01.04 MC) The Earth is a unique planet in that it is covered by more than 70 percent water. There are several properties of water that make Earth a suitable environment for life, including how the density of solid water (ice) is about nine percent less than the density of liquid water. Which best explains why this feature of water is important for marine life? (3 points)

(01.01 MC) In order to understand the impact of climate change, a scientist collected measurements of average yearly sea surface temperatures from 1880 to 2012. His data is graphed below. What scientific question could be most accurately investigated based on the data collected by this scientist? (3 points) © 2016 NOAA

(03.02 HC) Various methods of aquaculture can be used to grow species of marine fish. Consider the figure below, which shows one way that an aquaculture system can be designed to allow water to flow freely through the net. Explain whether this represents an open or closed system and one benefit of using this type of system. (3 points) © 2015, SeaChoice.org

(01.03 LC) Organisms living in the deep bathypelagic and abyssopelagic zones require oxygen for respiration. What process brings oxygen from the epipelagic zone to deeper oceanic zones? (3 points)

(02.01 HC) Fossil evidence has been used to understand the movement of continental plates. The figure below shows where fossils of Mesosaurus, a freshwater reptile, have been found. Evaluate the figure and compare Mesosaurus with other species. From the information given, which of the following is a possible explanation for why Mesosaurus is found in a smaller area than other species and why? (3 points) © 2016, The Geological Society
