Activity 1: Stimulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. The two variables that affect the rate of diffusion are: • The composition of the lipid layer‚ this content varies from tissue to tissue. For example kidney tissues have a high cholesterol content which makes them impermeable to water. • The size of the molecule‚ the larger the molecule the slower the rate of diffusion. 2. Why do you think the urea was not able to diffuse

For this reason‚ additional public funding is required to support rural transport provision. A portion
