A cell has 5% salt concentration. It is placed into a solution with a 0.5% salt concentration. What will happen to the cell

The cell will shrink due to osmosis.

Explanation:

As in given question the salt concentration are much more inside the cell, than outside. In order to maintain equilibrium. the water inside the cell will start flowing outside in order to maintain equilibrium, causing shrinkage of cell. The ability of a cell to divide or function will reduce because of water loss. This phenomenon is seen in case of hypertonic solution. Water will start diffusing from the higher concentration to the lower concentration.
