9. If the concentration of water inside a cell is lower then outside the cell, what will be the net movement of water molecules be? *
(1 Point)
a) Into the cell.
b) Out of the cell.

a) Into the cell.

Explanation:

The water molecules outside the cell would move into the cell until there is no net movement of water molecules. This process is known as osmosis.

Osmosis is the movement of molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane until the concentrations across the membrane are equal. That is, there is no net movement of molecules across the membrane.
