Answer :
Answer:Concentration gradient
Explanation: The osmotic gradient is the difference between two concentration solutions at either side of a semi permeable membrane that distinguishes the different percentage of a specific particle concentration that is dissolved in a solution. The osmotic gradient acts on solutions having a semi permeable membrane between them; allowing water to diffuse between the two solutions toward the solution with the higher concentration. Eventually, water with higher concentration will be equally diffused to the side of a lesser concentration. It creates equilibrium for water continues to flow equally both ways, resulting in a stabilized solution.
