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).

Punnett square predicts the percentage of offspring
Answer:
Increase
Explanation:
As CO2 enters the blood, most of it is converted to the carbonic acid in a reaction catalyzed by carbonic anhydrase. The carbonic acid dissociates into hydrogen ions and bicarbonate ions. As the H+ concentration increases, the blood pH decreases. Thus, the increased partial pressure of CO2 produces a more acidic environment. Increasing the volume of air that reaches the alveoli and takes part in gaseous exchange will increase the rate of removal of CO2 from the blood. The reduced CO2 levels in the blood would increase the blood pH.
