Question
What happens when concentrations of salt inside and outside of a cell are different?A.Salt particles flow into the cell, and water molecules flow out of the cell.B.Water molecules move through carrier proteins to the side with a lower salt concentration.C.Salt particles flow out of the cell, and water molecules are trapped inside the cell.D.Water molecules move across the cell membrane to even out the concentrations.SUBMITarrow_backPREVIOUS
Solution
The answer is D. Water molecules move across the cell membrane to even out the concentrations. This process is known as osmosis. When the concentration of salt inside and outside the cell are different, water will move from an area of lower salt concentration to an area of higher salt concentration in an attempt to balance out the salt concentration on both sides of the cell membrane.
