Question

When molecules of a gas or liquid move from greater concentration to a

lesser concentration through a selectively permeable membrane. This is
called.... *
Diffusion
Plasmolysis
Osmosis
Concentration gradient

Answer 1

Osmosis

Step-by-step explanation:

Osmosis is the diffusion of water or gas molecules, from a region of higher concentration to a region of lower concentration, through a partially permeable membrane

Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration.

Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell.

The difference in the concentration of a substance between two areas is called the concentration gradient.
