Detailed explanation-1: -Complete answer: The electrical charges of the diffusion particles are the only factor that does not have an effect on the rate at which diffusion occurs.

Detailed explanation-2: -These factors include the distance of diffusion, concentration of the substance and the molecular weight of the diffusing molecules. Therefore, C. the amount of energy available for transport molecules is not a factor since diffusion is a passive process.

Detailed explanation-3: -The rate of diffusion is affected by the concentration gradient, membrane permeability, temperature, and pressure. Diffusion takes place as long as there is a difference between the concentrations of a substance across a barrier.

Detailed explanation-4: -What factors affect the rate of diffusion in cells? The rate of diffusion in cells is affected by factors such as temperature, concentration gradient, size of the molecule, and the presence of a membrane.
