zzz [600]

Answer:

The correct answer would be - the cell will get water and expand.

Explanation:

If a cell with a higher salt concentration is placed ins a low salt concentration solution then the water will move through the cell membrane into the cell and the cell will swell or expand.

Water always moves from a low solute concentration to a high concentration area, therefore, if the cell has more salt concentration than outside the cell water move inside the cell which leads to an increase in the water concentration inside the cell and expands its size.
