Read the following statements and find out the incorrect statement.

Options

A. In diffusion, molecules move in a random fashion, the net result being substances moving from regions of higher concentration to regions of lower concen-tration.
B. Diffusion is a slow process and is not dependent on a living system.
C. Diffusion is obvious in gases and liquids, but diffusion of slids rather than in solids is more likely.
D. Movement by diffusion is passive as no energy expenditure takes place.

Answer

C

Explanation

In diffusion molecules moves in a random fashion, the net result being substances moving from regions of higher concentration to regions of lower concentration.
Diffusion is a slow process and is not dependent on a living system.
Diffusion is obvious in gases and liquids, but diffusion in solids rather than of solids is more likely.
Movement by diffusion is passive as no energy expenditure takes place.
