Animal Lesson 5

Question 1

Diffusion

Answer 1

Molecules move randomly due to their kinetic energy. Random movement causes a net flow from an area of
high concentration to an area of low concentration. The end makes it evenly spread out. There is random movement and bumping into one another to move along.

Question 2

Rate of diffusion?

Answer 2

is inversely proportional to distance. The farther the distance the slower the diffusion. Shorter distance equals fast diffusion.
