Answer 1

Answer:

Explanation:

Diffusion refers to the net movement of atoms or molecules from regions of high concentration to regions of low concentration. Molecules or atoms will move from regions of high concentration to regions of low concentration due to random particle movement, which results in a change in the concentration gradient of a sample.

Answer 2

Explanation :

Diffusion is the tendency of molecules to spread out in order to occupy an available space. Gasses and molecules in a liquid have a tendency to diffuse from a more concentrated environment to a less concentrated environment. Passive transport is the diffusion of substances across a membrane. This is a spontaneous process and cellular energy is not expended. Molecules will move from where a substance is more concentrated to where it is less concentrated. The rate of diffusion for different substances is affected by membrane permeability.

For instance, water diffuses freely across cell membranes but other molecules can not. They must be helped across the cell membrane through a process called facilitated diffusion.
