A solution contains 30% salt the cell has 50% salt whic image correctly depicts the cell solution and result when the cell is placed in the solution

You did not include the images however, it should be one that shows the cells swells as a result of Osmosis.

Osmosis is the process by which molecules from a solvent with a lower concentration of concentrate enter into a solvent with a higher concentration through a semi-permeable membrane.

A solution with less concentrate than the cell is said to be Hypotonic.

In this instance, the cell has the higher concentration of salt so water(assuming the solution has water) molecules will move from the solution into the cell. This will cause the cell to swell.

The picture attached shows a red blood cell in different solutions. The Hypotonic solution is how a cell looks in a solution with more concentrate than it.

genetic variation will increase because of a new habitat and food source.
