An animal cell placed in a hypertonic (salty) solution will
A
Stay the same
B
Shrink-get smaller
C
Swell-get bigger
D
None of the above
Explanation: 

Detailed explanation-1: -If we place a cell in the hypertonic solution like in sugar or salt solution, the cell will shrink. It is because the movement of water takes place from lower solute concentration to higher solute concentration i.e from inside sugar solution to attain equilibrium. It results in shrinkage of the cell.

Detailed explanation-2: -A hypertonic solution contains a high concentration of the solute compared to the solvent molecules. Which basically means, the water molecules are more inside the cell, than in the solution. So, the water molecules within the cells diffuse out and the solute molecules move in, making the cell shrink.

Detailed explanation-3: -When red blood cells are in a hypertonic (higher concentration) solution, water flows out of the cell faster than it comes in. This results in crenation (shriveling) of the blood cell.
