Answer:

The correct answer is <u>Peristalsis.</u>

<u />

Explanation:

<u>Peristalsis</u> occurs when the longitudinal, circular, and diagonal muscles that surround the organ forcefully push, churn and mix the contents of the stomach with the gastric juices.

Peristalsis, are all those movements resulting from the contraction of the digestive tract through its different muscle layers which transport the contents from the stomach to the anus, thus intervening in the digestion process

Dovator [93]

No. Yes phenotypes are important for example those with longer legs can run faster and hence escape predators

But genes also code for unseen proteins

For example, if a disease is introduced those with long legs won't survive but those who have the genes which code for the complimentary antibody have the ability to kill the pathogen and hence survive.

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.
