What would happen to a red blood cell that has a higher concentration of water on the outside of it than on the inside of it?
|
|
It would swell up.
|
|
|
It would stay the same size.
|
|
|
It would shrivel up and shrink.

|
|
None of the above

Explanation:
Detailed explanation-1: -When red blood cells are in a hypertonic (higher concentration) solution, water flows out of the cell faster than it comes in. This results in crenation (shriveling) of the blood cell.
Detailed explanation-2: -The diffusion of water across a membrane because of a difference in concentration is called osmosis. If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst.
Detailed explanation-3: -A blood cell placed in hypotonic solution would gain water as water will enter cell from surrounding hypotonic medium by the process of osmosis causing the cell to swell up.
