I guess it would have to be A
Answer:
E. that area of the membrane is in the absolutely refractory period.
Explanation:
Refractory period is a period during which neuron cell cannot be stimulated (depolarized). This is why the action potential can only travel in one direction from the neuron body towards axon.
Refractory period occurs because of the inactivation of voltage-gated sodium channels (while action potential is at its peak) which cannot be open for a certain period of time. and membrane cannot be depolarized.
They disguise themselves as white blood cells
7m + 19 would be the simplified answer
Hope this helps

Answer:
Explanation:
A reactant is a substance that take part or begin a chemical reaction and it is consumed during the reaction to form products. Reactant is on the left of the reaction.
