Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If a cell with 5% salt is placed in water with 20% salt, then the water is ____ to the cell.
A
hypertonic
B
hypotonic
C
isotonic
D
None of the above
Explanation: 

Detailed explanation-1: -Transferring the swollen red blood cells into a 5% solution (which is hypertonic) will drive the water molecules from the cells causing them to shrink. To allow the red blood cells to sustain their shape and vitality they should be placed in the isotonic solution (0.9% NaCl).

Detailed explanation-2: -For example, a solution containing 10% salt is hypertonic. When a cell is placed in a hypertonic environment, there is a net movement of water to the outside of the cell (from the higher water environment inside the cell). The cell shrinks in response. A solution of low solute concentration is referred to as hypotonic.

Detailed explanation-3: -Final answer: When the cell when it is placed in salt solution, it will shrinks.

Detailed explanation-4: -6. When plant cells are put in really salty water, water diffuses/moves out of the cell and the central vacuole shrinks. When animal cells are put in salty water, water diffuses/moves out of the cell and the cell shrivels up.
