Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a solution surrounding a cell is hypertonic how will water move?
A
It will move into the cell via osmosis
B
It will move out of the cell via osmosis
C
It will not move because equilibrium exists
D
It will evaporate from the cell surface more rapidly.
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: -Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.

Detailed explanation-3: -In biology, osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell’s partially permeable membrane.

Detailed explanation-4: -Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of lower concentration solution (i.e., higher concentration of water) to an area of higher concentration solution (i.e., lower concentration of water). Water moves into and out of cells by osmosis.
