Question

How does osmosis help a cell maintain homeostasis?

A. Salt particles flow across the cell membrane to balance the salt concentrations inside and outside of the cell.
B. Salt particles flow into a cell through the membrane until the cell bursts.
C. Water flows across the cell membrane to balance concentrations of another substance.
D. Water flows out of a cell through the membrane until the cell shrivels up

Answer 1

The answer is C “Water flows across the cell membrane to balance concentrations of another substance”.

Answer 2

C. Water flows across the cell membrane to balance concentrations of another substance.

Osmosis is a type of passive transport where water molecules move from an area of high concentration to an area of low concentration across a selectively permeable membrane. This movement of water helps to balance the concentration of solutes (such as salt, sugar, or ions) on either side of the membrane.
