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).

The factory can affect the carbon cycle by releasing carbon dioxide into the atmosphere. Because carbon dioxide is a , it can tr
Bas_tet [7]
Because carbon dioxide is a GREENHOUSE GAS, it can trap the sun's heat in the atmosphere. Because the factory is made of concrete, it may deplete groundwater levels overtime by not allowing water to INFILTRATE.

Greenhouse gases trap the sun's heat and this is how we can feel it. Without greenhouse gases the earth's average temperature would be 30 degrees less. Other greenhouse gases include water vapor and methane. Increases in the levels of Greenhouse gasses are responsible for present day global warming.

Infiltration is the process by which water enters the soil and eventually becomes part of the groundwater.

Un gas puede condensarse al disminuir su temperatura?
myrzilka [38]

Answer:

Si.

Explicación:

Sí, un gas se puede condensar cuando su temperatura disminuye porque cuando la temperatura del área circundante del gas disminuye, se produce una condensación que cambia el estado de la materia i. mi. de gas a estado líquido. La principal razón de esta condensación es la aproximación de moléculas de gas que están muy alejadas unas de otras. Con una temperatura más baja, el volumen disminuye y las moléculas de gas se combinan para formar un líquido.
