What happens if you place human red blood cells in a concentrated salt solution

AThey shrink as water moves from inside to outside the cells as a result of osmosis
BThey burst as one to move from outside to inside the cells as a result of osmosis
CNo change occurs as water freely diffuses back-and-forth across the cells membrane
DDeSales expand energy pumping water out in response to the great external salt concentration

Verified Answer :

Answer:

The correct answer would be a. They shrink as water moves from inside to outside the cells as a result of osmosis.

Osmosis refers to the movement of water from the region of high solvent or water concentration to the region of low solvent or water concentration.

In this condition, the concentration of water in a concentrated salt (hypertonic) solution would be less as compared to that of a red blood cell.

Thus, the water from inside the cell will move outside the cell. Consequently, the cell would shrink in size.

If we place human red blood cells in a concentrated salt solution, then they shrink as water moves from inside to outside the cells as a result of osmosis.


Further Explanation:

Osmosis refers to the spontaneous movement of the solvent particles via a semi-permeable membrane from a lower to the higher region of concentration, in the direction which tends to maintain equilibrium onto both sides.  


For a cell to survive, the ion concentrations outside and inside the cell should be the same. Also, the water concentration is limited because a higher concentration of water can burst and swell the cell. Osmosis is crucial in the biological systems as the membranes are semi-permeable. Also, focus on maintaining the equilibrium on both sides and prevent the bursting of the cell. If a blood cell is placed in a beaker that is filled with the concentrated salt solution then the solvent present in the cell moves outside to the cell to maintain the homeostasis of the cell this phenomenon is mainly known as exo-osmosis.
