Answer:

membrane potential reaches threshold

many voltage-gated Na+ channels open

Na+ ions rush into the cell

membrane potential rises

Explanation:

During resting condition, the axon membrane is polarized and has a voltage of -70mV. However, when action potential occurs after reaching the threshold level (voltage is equal to -55mV) after which the axon membrane first depolarizes and then polarizes again to reach the initial resting state. The threshold potential open the sodium voltage gates channels thereby allowing sodium ions to enter into the cell. As the sodium ion enters the cell, the membrane potential become less negative. When the membrane potential reaches the mark of +30mV, the sodium gated channels closes and potassium voltage gated channel opens.

How is carbon<br> exchanged between<br> living and the<br> nonliving parts of the<br> environment?
Ede4ka [16]

Answer:

Carbon dioxide from the air is used to produce food for plant growth. Carbon moves from plants to animals when animals eat the plants. Also, Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere.

The burning of fossil fuels also releases carbon dioxide into the atmosphere.
