When a red blood cell is placed in hypotonic (very dilute) solutions of NaCl water enters the cell, and the cell swells. water enters the cell, and the cell shrinks. water leaves the cell, and the cell swells. water leaves the cell, and the cell shrinks.

Solution

Your answer is \"water enters the cell, and cell swells\".

Explanation:-

A red blood cell has biconcave shape and has a semipermeable membrane which allows for osmotic regulation. The intracellular fluid of RBC has a solution of salts, glucose, and hemoglobin. Osmotic regulation depends on the concentration gradient of non-diffusible ions on each side of the membrane. When a red blood cell is placed in hypotonic solutions of NaCl, ( a solution with lower solute concentration than the cell ) water moves into the cell for osmotic regulation for that reason cell swells.
