Which one of these is not an example of intracellular communication?

a. control of cell division

b. reaction of pheromones

c. molecule in a cell changes function of cell

d. molecular movement within a cell

The answer is B

Explanation:

Controll of cell division, changes in the function of a molecule or molecular movement are all processes that occur inside the cell membrane. However, a reaction of pherormones needs intercellular communication, once pherormones are secreted or excreted chemical factors that triggers a social response in members of the same species. Because pherormones come from outside the body they represent intercellular communication.
