(01.02 LC) A model of sea ice coverage is made with sketches and diagrams. It shows that ice cover increased in the Antarctic and decreased in the Arctic from June to July. What type of model is this? (3 points)

What are the filaments/strands of fungi called? 

How do extremely high temperatures affect bacteria? 

(01.03 MC) Why are there fewer phytoplankton in the mesopelagic zone relative to the epipelagic zone? (3 points)

(03.02 MC) When kelp plants in coral reefs are exposed to sunlight, blue and red wavelengths of light are absorbed by the kelp. Energy from green wavelengths is lost to the kelp. Explain why this phenomenon does not violate the Law of Conservation of Energy. (3 points)

(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)
