Question

You place a cell in a solution that contains 12 more water molecules than the inside of the cell. How will you know when the cell reaches equilibrium?

A. when there are equal numbers of water molecules on both sides
B. when the water molecules stop moving across the cell membrane
C. both A and B
D. The cell will not reach equilibrium because water cannot pass through the cell membrane.

Answer 1

B

Step-by-step explanation:

the water molecules will stop moving across the

cell membrane because the cell membrane has

the same amount of water as in the solution.

This process is called osmosis.
