semipermeability

Example:The semipermeable membrane in the kidneys helps to maintain the balance of water and dissolved substances in the body.

Definition:A membrane that allows certain molecules or ions to pass through while blocking others based on size and charge. It is crucial in many biological systems and artificial filters.

Example:The osmotic pressure of a solution can be calculated based on its concentration and the semipermeability of the membrane.

Definition:The force exerted by a solution to stop the net movement of water across a semipermeable membrane during osmosis. It is essential in the study of fluid and solute movements in biological and chemical systems.
