If the concentration of sodium is greater outside a cell than inside the cell, which process could move sodium out of the cell?

Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration. This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood. 

It will dry out with less sunlight

Nine months old i think but i’m not that sure
