(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

(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

(02.02 MC) In recent years, scientists have collected data on populations of Adelie and Gentoo penguins. Adelie penguins are ice dependent. They rely on sea ice as a foraging platform for feeding on prey such a krill and fish, while Gentoo penguins are considered ice-intolerant. How does the data in the graph support or refute the theory of global climate change? (3 points) © 2016, NOAA
