Answer:
An infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.
The electrical impulse travels across the axon, and the myelin sheath helps to increase transmission speed.
bacteria can live in hotter and colder temperatures than humans but they do best in a warm moist protein-rich environment that is pH neutral or slightly acidic
I would say the answer is transport work!
Substances can go through the cell membrane through active and passive transport! Active transport is powered by adenosine triphosphate, ATP!
