Answer 26

Cell or organ that carries out corrective action to restore homeostasis

Question 27

What is positive feedback?

Answer 27

A self-amplifying cycle, leads to more change in same direction

Answer 29

They flow down, from high concentration to low concentration

Question 30

What is cell theory?
