What eventually happens to the concentration of a substance that moves across a membrane due to diffusion?

• The concentration becomes greater inside the membrane.

• The concentration becomes unequal on both sides of the membrane.

• The concentration becomes greater on the outside of the membrane.

• The concentration becomes the same on both sides of the membrane.

A cell that is made up of 15% salt is placed into a beaker that has a solution made up of 45% salt. What happens to the cell?

• The cell will lose water and shrink.

• The cell will absorb water and swell.

• The cell will have no movement of water and remain the same.

• The cell will have equal movement of water and remain the same.
