During the course of an action potential, the membrane potential rapidly rises and reaches a peak of about +40 mV before falling
ad-work [718]

Answer:

A)  A decrease in Na+ permeability, and an increase in K+ permeability.

Explanation:

When the potential action reaches a peak of about +40 mv Na+ channels are open and a high number of Na+ ions are entering the inside of the cell. Shortly after this happens the K+ channels will start to open their gates increasing the cell  K+ permeability  while the Na+ channels will start to close their gates, so the Na+ permeability will decrease. This happens  in order to valance the positive charge on the inside of the cell. Normally the inside has a negative charge while the outside has a positive one, as the inside is more positive due to the increase in Na+ permeability at the beginning of the potential action, K+ cations (which are in abundance in the cell) will have to go out through the K+ channels  so as to restore the charge valance, that means that there is an increase in K+ permeability.

The correct answer is: 2- Hypertension, or high blood pressure

Hypertension leads to heart failure. Also, as a result of hypertension body tends to retain fluid in order to maintain adequate blood volume. A failing heart is unable to handle that extra fluid, so it is transferred out of the blood vessels and into tissues causing the swelling of extremitets or edema.

choli [55]

Answer:

Estrous cycles give females repeated opportunities to become pregnant throughout their productive lifetime. The cycle is regulated by the hypothalamic-pituitary-gonadal axis, which produces hormones that dictate reproductive events.
