The hydrostatic pressure that makes a diluted solution diffuse solvent molecules across a semipermeable membrane into a concentrated solution is known as

a. osmotic pressure.
b. ambient pressure.
c. absorption pressure.
d. adsorption pressure.

The correct answer to the statement above is letter A, osmotic pressure.

It is because the osmotic pressure is a kind of pressure where it is applied to a certain solution. It is being applied to a certain solution for the prevention of having it to flow in an inward motion which takes place across the semipermeable membrane.

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

dynamic equilibrium is the answer.
