Use the following information to for Questions below. High levels of dissolved carbon dioxide can increase the acidity of water and potentially harm the marine life living there. Scientists conducted an experiment to see whether increased acidity affects hearing in fish. One hundred fertilized eggs from the same parent fish were placed in three separate tanks of water. Tank A contained water with the usual atmospheric pressure of carbon dioxide (400 microatmospheres). The carbon dioxide pressure levels in Tanks B and C were 800 microatmospheres and 1,200 micro atmospheres, respectively.... Show more Use the following information to for Questions below.

Once the fish reached maturity, underwater speakers placed at one end of each tank played the sounds of the fish’s natural predators (these sounds could be heard only when the fish were near the speaker). The positions of the fish in each tank were recorded throughout the experiment. It was found that the fish raised in elevated carbon dioxide levels did not avoid the sound of the predators. However, the fish raised in regular carbon dioxide levels did avoid the end of the tank that had the speaker. Show less
