Answer:

The correct answer would be - the potassium ions continue to move out of the axon.

Explanation:

During transmission of the impulse when sodium channels are closed and potassium channels are open, the cell membrane of the axon cell becomes hyperpolarized due to the continuous movement of the potassium ion to outside the axon. During this refractory period, the impulse can not be fire or generated.

Thus, the correct answer would be - the potassium ions continue to move out of the axon.

What is the main similarity between the processes of artificial selection and natural selection?
Gnesinka [82]
Natural selection involve natural causes while artificial selection is by human breeding or human intervention.
The process of domestication is called artificial selection. Like natural selection, artificial selection acts by allowing differential reproductive success to individuals with different  genetically determined traits in order to increase the frequency of desirable traits in the population. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene.
