Question

The Atlantic cod is a common fish of the Atlantic Ocean that must drink seawater to meet its water needs. Explain how active transport helps the Atlantic cod maintain homeostasis with regard to the balance of sodium and chlorine ions, which are abundant in seawater.

Answer 1

the salt water has a lot of sodium and chlorine ions. Normally, they would enter the cell, but if this were to occur, the cell would shrivel and not function. Therefore, the cells use active transport to remove the ions against the gradient.
