Which of the following characteristics are true for an action potential?

Biology
1 answer:
pickupchik [31]3 years ago
6 0

Answer:

I, II, III

Explanation:

A threshold stimulus is a stimulus that is capable to produce a response in excitable tissues such as neurons and muscle fibers. At threshold potential, the outward movement of K+ and inward movement of Na+ become equal to each other. When the potential exceeds the threshold potential, more and more Na+ enter the cell to depolarize it and to allow the opening of Na+ channels. Therefore, to fire an action potential, the threshold must be exceeded.

Conduction of action potential is all or none phenomenon which means that either it occurs or it does not occur. As an impulse is passed by each successive part of an exon, it enters the refractory period during which there is no conduction of nerve impulse. It ensures the one-way conduction of impulse from the cell body to the axon terminal only.

people once believed organisms could grow from food or dirt.How might the scientific study of cells have affected this view?
almond37 [142]
It proves that living organisms MUST come from other living organisms, an egg couldn't magically appear in a pile of chicken seed, a hen would have had to lay the egg first, just as a nucleoulus makes ribosomes so the cell can have proteins, the proteins don't just materialize within the organism.
