D)metabolically inactive.

Question

Quizplus · Accepted Answer

A cell that has neither a net gain of water nor net loss of water is in a state of equilibrium, which means that the concentration of solutes both inside and outside the cell is the same. This type of solution is called an isotonic solution. If a cell has a net gain of water, it is in a hypotonic solution, and if it has a net loss of water, it is in a hypertonic solution. Therefore, the best choice is A, isotonic to its environment.
