(01.01 MC) A marine scientist is studying photosynthetic organisms, which use sunlight to produce their own food. She observes that they tend to populate shallower ocean depths. She concludes that photosynthetic organisms can only live in areas of low pressure. Why is this an invalid scientific conclusion? (3 points)

(01.02 HC) The graphs below show the change in temperature and salinity of a region of ocean as an instrument is lowered below the surface. Depth is measured in kilometers below the surface, temperature in degrees Celsius, and salinity in parts per thousand. © 2015 protonsforbreakfast.wordpress What is the most valid conclusion based on the data? (3 points)

(01.01 MC) A Spanish scientist observes that salmon produce more eggs when grown in warmer aquariums. He asks his colleague in the United States to conduct the same experiment using the same aquarium equipment. Should he expect the results to be similar? (3 points)

(01.03 MC) Most species of fish require dissolved oxygen for their metabolism. Why would these species tend to be found in shallow ocean zones? (3 points)

(01.01 LC) What does a sound scientific conclusion most likely rely upon? (3 points)

(03.01 MC) Scientists have observed that polar bears are moving farther inland and hunting and eating more birds in arctic regions. What is the best explanation that can be made using this information? (3 points)

(02.05 LC) Increased carbon in the oceans has caused the pH levels of the water to decrease. What is the largest impact of this ocean acidification on marine life? (3 points)

(01.01 MC) A professor researching seaweed at a laboratory in the United States has been offered a position at a Chinese university. She needs to decide whether to move her experiments to China or whether to start the experiments over. Would it be appropriate scientific methodology to transport her experiments to China and continue them there? (3 points)
