Question

XWhich statement best describes diffusion?

A.
Diffusion requires the cell to use energy.


B.
Diffusion is an example of active transport.


C.
Diffusion occurs when particles spread from areas where they are less concentrated to areas where they are more concentrated.


D.
Diffusion occurs when particles spread from areas where they are more concentrated to areas where they are less concentrated.

Answer 1

Answer: Diffusion is the spread of particles from where they are more concentrated to where they are less concentrated

Explanation: When particles(solute) move from their higher concentration to their lower concentration it is called diffusion.

Diffusion is a passive process hence it does not require energy. It only requires a concentration gradient of particles to be present as it occurs along the concentration gradient.

diffusion stabilizes the number, movement & energy of solution on all sides.
