Question

abnormal osmotic pressure

Answer 1

Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.
It is also defined as the measure of the tendency of a solution to take in water by osmosis. 
Potential osmotic pressure is the maximum osmotic pressure that could develop in a solution if it were separated from distilled water by a selectively permeable membrane.
The phenomenon of osmosis arises from the propensity of a pure solvent to move through a semi-permeable membrane and into a solution containing a solute to which the membrane is impermeable.
This process is of vital importance in biology as the cell's membrane is semipermeable.

Answer 2

Abnormal Osmotic Pressure

Explanation:

Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. It is also defined as the measure of the tendency of a solution to take in pure solvent by osmosis.

This process is of vital importance in biology. Cell membranes are semipermeable and the exchange of water and nutrients between cells happen through bloodstream using osmosis. Abnormal osmotic pressure will affect health as cells might retain more water or nutrients may not get absorbed, etc.
