Net movement of molecules across the nuclear membrane until the number of molecules on each side is nearly equal
Explanation:
The net spontaneous movement of the molecules of a solvent through the selective membrane to an area of higher concentration of the solvent is the process of Osmosis.
By this process in a solvent separates the 2 solutions of various concentrations. The pressure through which the movements were initiated is the ‘osmotic pressure’. The membrane should be permeable for molecule movements.
If the pH goes up than the coral reefs wouldn't be able to live and if they can't live there then there wouldn't be any life. There wouldn't be shelter for the fish and if there is no fish then the ecosystem would collapse.
