Question

What happens if you place human red blood cells in a concentrated salt solution?
They shrink as water moves from inside to outside the cells as a result of osmosis.
They burst as water moves from outside to inside the cells as a result of osmosis.
No change occurs as water freely diffuses back and forth across the cell membranes.
The cells expend energy pumping water out in response to the greater external salt concentration.

Answer 1

They burst as water moves from outside to the inside of this cell;

They will swell and explodeIn salt water. This is called hemolysis. they will shrinkIn isotonic solution . this is called crenation. This is because of osmosis, water will travel wherever there is a higher concentration of minerals, hence the cells swelling in water.

Answer 2

Actually, the answer is: They shrink as water moves from inside to outside the cells as a result of osmosis.
