Which statements always apply to the process of diffusion? Check all that apply.

Molecules move from high concentrations to low concentrations.

Molecules move from inside of the cell to outside of the cell.

Diffusion requires proteins in the cell membrane.

Molecules are evenly distributed at the end.

Diffusion requires energy.

- Molecules move from high concentrations to low concentrations.

- Molecules are evenly distributed at the end.

Explanation:

Diffusion is a process that involves the movement of solute or gaseous molecules from the region of higher concentration of the molecules to the region of lower concentration of the same molecule.

The movement of diffusing molecules is random and hence, they are evenly distributed in space at the end of the process.
