The greatest surface area for gas exchange is found in the Alveoli
Answer: Cell with membrane potential have EXCITABILITY, thus, the correct option is C.
Explanation:
Membrane potential refers to the difference in electric potentials between the inside and the outside of the cell membranes of living organisms. This difference in electric potential give the cell membranes the ability to receive and to respond to stimuli, this ability is called excitability.
The central nervous system is responsible for processing stimuli information and sending out appropriate responses to different parts of the body including the muscles. The muscles tissues are able to respond to the directions of the nervous system to contract or to relax because of their ability to be excited due to the potential differences between the outer and the inner plasma membrane.

of the backbone are best described as slightly movable. Slightly movable joints
are formed by bones that are separated by a substantial space and united by
