Concentration of Liquids

When particles move from areas of high concentration to areas less concentrated, this has taken place.

• diffusion

• mitosis

• endocytosis

• photosynthesis

Diffusion stops when the concentration is evenly spread out - true or false?

• 100% definitely true.

• Could be false though.
