Which statements always apply to the process of diffusion molecules move from high concentration to low concentration molecules move from inside a cell to the outside of cell diffusion require protein in the cell membrane molecules are evenly distributed at the end and diffusion requires energy

Option A = molecules move from high concentration to low concentration.

Explanation:

Diffusion:

It is the physical process in which molecules move from higher concentration region to lower concentration region.

The molecules that diffuses are solid, liquid or gases. The medium also could be the three state of mater.

The diffusion rate depends upon the interaction of medium and material.

For example:

1. The gas molecules are diffuse into another gas very quickly. While gas molecules spread slowly into water and solids thus diffusion rate became slow.

2. The sugar is spread into a cup of tea.

3.  Carbon dioxide inter into stomata.

4. The cooked food odor in the kitchen and when door is open odor spread out side.
