(03.01 MC) Sea turtles spend most of their lives at sea feeding on jellyfish. When it is time to lay their eggs, mature females come ashore. They dig nests in the sand along the coast, lay their eggs, and then return to the sea. The data below show the changing sea levels since the late 1800s. © 2016 NEAQ.org If the current trend shown in the graph continues, what prediction is most likely regarding the future of sea turtles? (3 points)

(01.01 MC) The oxygen level of a lake suddenly starts decreasing. A biologist believes that photosynthetic organisms in the community have become less efficient at producing oxygen. A geologist believes that changes in the ground have increased the inflow of water into the lake. Why are both of these options valid scientific hypotheses? (3 points)

(02.03 LC) What weather factor is also a measurement of energy held within the air? (3 points)

(02.02 HC) Volcanic eruptions produce lava, which is molten rock that eventually cools into a solid. The gases released during an eruption become trapped in pockets within the lava that remain when the lava solidifies. Scientists can later extract these gases to determine which gases were produced during the eruption, and in what quantities. The table below shows the percent concentration of gases found after the eruption of Mount Saint Helens in Washington, USA. Gases produced during eruption Percent molar concentration H2O 91.58 H2 0.85 CO2 6.64 CO 0.06 SO2 0.2089 H2S 0.3553 S2 0.0039 © 2016 Oregon State EduDo these findings allow the inside-out model to be elevated to a scientific theory? Why or why not? (3 points)

(02.06 LC) Which of the following best defines the carbon cycle? (3 points)

(03.03 LC) The distance from a wave’s equilibrium point to its crest is known as what? (3 points)

(01.01 MC) A scientist wants to test whether the pH, salinity, or temperature of seawater impacts coral development. He sets up an experiment with three conditions: Aquarium 1: Normal pH, normal salinity, normal temperatureAquarium 2: High pH, high salinity, high temperatureAquarium 3: Low pH, low salinity, low temperature What factor would improve experimental design the most? (3 points)

(03.03 MC) A marine biologist is working on a research vessel to study whale calls. His recording devices are measuring depths above 1,000 meters. As his vessel travels to cooler waters and begins to measure at greater depths, the marine biologist needs to make adjustments to his monitoring devices. Why is that? (3 points)

(03.02 MC) A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. His measurements are shown in the graph below. Based on this data, he concludes that the aquarium cannot be considered an isolated system for this experiment. Explain how he came to this conclusion. (3 points)

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