what movement of particles is diffusion?

Select one of the following:

  • movement from an area of high concentration to an area of low concentration

  • movement from an area of low concentration to an area of high concentration

Explanation

Explanation

Question 4 of 8

1

Whats the difference between diffusion and facilitated diffusion?

Select one of the following:

  • theres no difference

  • facilitated diffusion uses carrier proteins
