(03.02 HC) A dolphin is living in a closed system consisting of a large aquarium, the dolphin, and its food. Which method could be used to demonstrate the Law of Conservation of Energy? (3 points)

(03.02 MC) A fish eats food, and then swims. How does this example show the Law of Conservation of Energy? (3 points)

(02.01 MC) What aspect of mid-ocean ridges provides the mechanism that allows plate tectonics to occur? (3 points)

(03.01 MC) Polar bears obtain the majority of their annual nutrient reserves during the late winter. They hunt seals on the surface of sea ice. During this time, the sea ice is also at its highest density. Scientists have been measuring the amount of arctic sea ice for decades, and their results can be seen below. © 2016 Nasa.gov Based on the data trends in the graph, what is the most likely prediction regarding the polar bear? (3 points)

(01.01 MC) Students in a high school Marine Science class are learning about the scientific process. Four students were asked to write a testable prediction about ocean temperature. Their responses are shown in the chart. Student Response Kyle Ocean temperatures will be 22°C in the year 2050. Xavier The salt in oceans causes the temperature to be colder in the summer than in the winter. Rose The ocean temperatures were colder prior to the existence of bony fish. Laurie Ocean temperatures must remain constant in order to go surfing. Which student’s prediction is the most testable using the scientific process? (3 points)

(03.01 LC) In what location would primary succession most likely occur? (3 points)

(01.03 MC) In which zone do some aquatic organisms rely on bioluminescence to entice prey? (3 points)

(02.01 MC) The theory of plate tectonics is supported by evidence that some sediment layers on the floor of the Atlantic Ocean are thinner than expected. How does this observation support the theory of plate tectonics? (3 points)

(02.02 HC) Scientists have found that Mars has water ice at its poles, even though volcanic activity has never been observed on Mars. Would this prevent the inside-out model from becoming a theory? (3 points)

(03.01 MC) Loggerhead turtles need an incubation temperature between about 28 and 32 degrees Celsius. When temperatures are higher, more female turtles are produced. When temperatures are lower, more males are produced. When the temperatures exceed this range, the offspring don’t develop and die. Scientists have observed that, in Florida, 90 percent of the turtles born are females. If global climate change continues, what is the best prediction that can be made based on these observations?
