Answer:
I believe your answer should be B.) Materials were pulled together by gravity. I hope this helps you!
As sodium ions diffuse inward, sodium channels open.
Membrane depolarization occurs.
Potassium ions spread outward as potassium channels open.
Membrane repolarization occurs.
<h3>What happens along an axon in the right order ?</h3><h3 />
An action potential, which is a fast change in membrane potential, develops when the membrane potential of a neuron's axon hillock hits threshold. There are three steps to this shifting change in membrane potential. Depolarization occurs first, then repolarization, and then there is a brief phase of hyperpolarization.
- A depolarizing current causes an explosion of electrical activity known as the action potential. This indicates that the resting potential shifts toward 0 mV as a result of some action (a stimulus).

Answer:
The answer is: a. Climacteric
Explanation:
Climacteric is the time in the midlife of a woman that starts with the diminution in ovarian activity (less production of estrogen and progesterone) until the end of ovarian function. It is the compilation of gradual changes of ovarian function that happen before the menopause (cessation of menses) and continue for a while.
The phases of the climacteric are pre-menopause, menopause and post-menopause. During the pre-menopause, hormonal changes will take place, there is a decrease in estrogen and progesterone production.
