Question 2

Osmosis

Answer 2

Question 3

Factors of diffusion

Answer 3

Temperature. As temperature increases the average kinetic energy of particles increases. …
Density of the Diffusing Substance. Density is defined as the amount of material that exists within a given volume. …
Medium of Diffusion. Diffusion also depends upon the medium in which it takes place. …
Concentration Gradient.

Question 4

Why is diffusion important

Answer 4

Diffusion is important to organisms because it is the process by which useful molecules enter the body cells and waste products are removed. Digested food molecules (amino acids, glucose) move down a concentration gradient from the intestine to the blood.
