(03.03 MC) Dolphins use echolocation to help them navigate. They emit a sound that bounces off objects in front of them. Dolphins are able to navigate their surroundings based on how long it takes the sound to return. What property of waves are dolphins using to help them find their way around their environment?

(03.05 MC) How are temperature and salinity related in a thermohaline circulation pattern? (3 points)

(01.03 HC) Based on your knowledge of ocean chemistry, predict the feeding mode and size of organisms found in the deep layers of the ocean, and select the best explanation. (3 points)

(03.02 MC) A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. He concludes that the aquarium is an open system. Explain why this conclusion is invalid. (3 points)

(03.02 MC) A marine scientist measures the energy found in a system consisting of seagrass and sunlight. After the seagrass grows for one week, the marine scientist concluded that radiant energy from the sunlight was transformed to chemical energy in the seagrass. Does this result validate or invalidate the Law of Conservation of Energy? (3 points)

(03.03 LC) Why does the ocean appear blue in color? (3 points)

(03.06 LC) The pattern of low and high tides changes the daily habitat for organisms living in intertidal zones. Which condition, specific to the intertidal zone, is especially detrimental to organisms not adapted to low tide? (3 points)

(03.02 MC) A marine scientist measures the energy found in a system consisting of a shark and fish. After the shark consumes the fish, the marine scientist concluded that chemical energy from the fish was transformed to kinetic energy in the shark. Does this result validate or invalidate the Law of Conservation of Energy? (3 points)

(02.03 MC) As sea levels rise, which of the following will affect marine biodiversity? (3 points)

(03.01 MC) Cod grow and reproduce best when the temperature is below 54 degrees Fahrenheit. The following graph shows the temperature anomalies from 1960 to 2015. Temperature anomaly refers to the way in which the temperature is different from the long-term average. If the anomaly is negative, that means the temperature is lower than normal; if the temperature anomaly is positive, the temperature is warmer than normal. © 2016 NEAQ.org According to the graph, what prediction can be made regarding the ecosystem in which cod live?
