Which graph shows an organism returning to homeostasis?
Which type of membrane transport is shown here?
Simple diffusion
Facilitated diffusion
Active transport
endocytosis
What is the difference between simple diffusion and facilitated diffusion?
Facilitated diffusion requires a protein channel.
Facilitated diffusion requires extra energy
Facilitated diffusion goes from low concentration to high concentration.
Simple diffusion is for larger molecules.
