A) isotonic to its environment.
B) hypertonic to its environment.

Question

Quizplus · Accepted Answer

When a cell has neither a net gain nor loss of water, it means that the water concentration on the inside and outside of the cell is equal. This means that the concentration of solutes (such as ions or molecules) is also equal on both sides of the cell membrane. Such a solution is called isotonic, and because the water concentration is equal, the cell is also isotonic to its environment.
