The physical process by which water and solute move through a membrane when a hydrostatic pressure gradient exists across the membrane is the process of:
dialysis.
osmosis.
diffusion.
filtration.
The Correct Answer is D
A. dialysis: This is the separation of smaller particles from larger ones through a membrane, usually driven by concentration, not just hydrostatic pressure.
B. osmosis: This is the movement of water driven by a concentration gradient of solutes, not hydrostatic pressure.
C. diffusion: This is the movement of particles from high to low concentration.
D. filtration: Filtration is the process where hydrostatic pressure (like blood pressure) forces water and small solutes through a membrane or capillary wall.

B. Nervous: Nervous tissue has the least regenerative capacity, particularly in the Central Nervous System.
C. Epithelial: Epithelial tissues (like skin and the lining of the gut) constantly undergo cell division and have a high capacity for repair and regeneration.
D. All of the above: Incorrect, as the capacity varies wildly between these tissue types.
