Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An animal cell placed in a hypertonic (salty) solution will
A
Shrink
B
Swell
C
Stay the same
Explanation: 

Detailed explanation-1: -In a hypertonic solution, the net movement of water will be out of the body and into the solution. A cell placed into a hypertonic solution will shrivel and die by a process known as plasmolysis.

Detailed explanation-2: -When an animal cell is placed in a hypertonic solution, then water moves out of the cell as a result of exosmosis. So, when an animal cell will be placed in a hypertonic solution then it would lose water and shrink.

Detailed explanation-3: -If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Detailed explanation-4: -Note: When the animal and plant cell are placed in a hypertonic solution, the cell shrinks, because it loses water. Water moves from higher concentration to lower concentration.
