DIFFUSION AND OSMOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
what happens to bloods cells of the concentration of salt outside the cells is higher than the concentration of salt inside the cell?
A
water diffuses into the cell
B
water diffuses out of the cell
C
the cell expands and ruptures
D
the cell manufactures salt to make the concentration
Explanation: 

Detailed explanation-1: -When a solution has a higher concentration of solute than a cell that it surrounds, the solution is hypertonic. When a cell is in a hypertonic solution, osmosis will cause water to flow out of the cell to balance the concentration of solute on either side of the semipermeable membrane.

Detailed explanation-2: -Salt Sucks, Cells Swell Water in cells moves toward the highest concentration of salt. If there is more salt in a cell than outside it, the water will move through the membrane into the cell, causing it to increase in size, swelling up as the water fills the cell in its imperative to combine with the salt.

Detailed explanation-3: -Answer and Explanation: If a red blood cell (RBC) found itself in a concentrated salt solution, the solute concentration would be higher outside the RBC than inside it. Water would move out of the cell via osmosis, and the cell would become shriveled and dysfunctional.
