Answer:
The rate of osmosis increases with increasing differences in solute concentrations between two solutions separated by a selectively permeable membrane.
Explanation:
Osmosis is the movement of solvent from an area which is having a low concentration of solute to an area having a high concentration of solute through a semi-permeable membrane. It is a type of diffusion and does not require any energy to occur. Osmosis helps cells to maintain their osmotic pressure and maintain the cell shape.
So if the difference in solute concentration between two solutions which are separated by semi-permeable membrane increases than the rate of osmosis will increase to maintain the balance of solute concentration of both the site.
