Cells don't need to use any ENEGRY for diffusion particles to occur/happen
two molecules must collied before diffusion happens.
Diffusion occurs when a substance moves from an area of high concentration to an area of low concentration. This will happen naturarally without disruption, But is more common (and will happen faster) in a warm environment.
Capillaries must allow diffusion too allow for exchange of oxygen. Without oxygen, the eventual consequence would be death.
For diffusion to occur there needs to be a concentration gradient. Which means that the concentrations on the two sides must be different. In diffusion the particles flow from high concentration to low concentration.
mating must happen randomly
diffusion is occur when different concentration gradient is applied
For a new moon to occur the moon must be between earth and the sun
