What is homeostasis? How do cells use both diffusion and osmosis to help maintain homeostasis?
arlik [135]

Answer:

Osmosis is the process cells use to move water molecules in and out of the cell through the cell membrane. When cells are put in different environments they will try to maintain an equilibrium with the water concentration outside the cell. Through osmosis the cell will lose or gain water molecules to become equal to the concentration in their environment.

What is the correct sequence of events along an axon that follows a membrane reaching threshold potential?
Oksi-84 [34.3K]

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).
