Select three findings that show that behavior has a genetic component. A. It was found that mice who do not engage in nurturing, maternal behavior with their newborns lacked a certain gene that produces a specific protein. B. Scientists isolated an egg-laying hormone (a protein) that causes the marine snail Aplysia to lay eggs even if it has not mated. C. When two species of lovebirds were interbred, the hybrid birds had difficulty carrying nesting material. D. Chicks of laughing gulls improve their ability to peck a parent's bill in order to get the parent to regurgitate food during the first few days in the nest.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
