Maintaining a stable internal environment is called a. heterostasis c. biological control b. homeostasis d. none of the above

b., homeostasis. It has to be 20 characters so...

Correct C). Homeostasis

Homeostasis can be defined as the ability of the body to maintain a constant environment irrespective of change in the external environment.

It is vital for the body to maintain a constant body temperature because it is required for the normal functioning of the bod. The mechanism of homeostasis is maintained by the body temperature, blood sugar, body fluid etc.

Hence, the correct answer would be Homeostasis.

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.
