In a neuron, the opening of sodium gates typically leads to open and allows the exit of sodium ions out the cell. The neuron that contains for why myelinated fibers conduct signals faster than unmyelinated fbers are the diffusion of ions along the axoplasm is faster. At the same time, a traveling wave of excitation is a nerve signal.

Explain how Co2 is able to control fires? <img src="https://tex.z-dn.net/?f=co2" id="TexFormula1" title="co2" alt="co2" align

Alborosie

Carbon dioxide is heavier than oxygen gas. It therefore displaces the oxygen gas around a flame. Without oxygen, the combustion reaction will stop and the flame will be put out.

Further Explanation:

In order for a combustion reaction to happen, three components must be present: fuel, oxygen, and heat to cause ignition. When one of these three is removed, the combustion reaction will stop.

CO2 fire extinguishers use the difference in mass of the CO2 and oxygen molecules to stop the fire. Since CO2 is heavier, it will displace any oxygen molecules that are around the flame. When this happens, the supply of the oxygen will be limited or cut-off and the fire will eventually be put out because of the lack of oxygen. This ability to displace oxygen is also what makes using CO2 as fire extinguisher quite dangerous for the user since it pushes away the oxygen that is needed for respiration.

Other ways to put out fire include spraying liquids that absorb the heat to avoid spreading the fire further or spraying substances that coat the fuel (flammable materials) to avoid contact with oxygen gas which can lead to further combustion.

In your own words wright a paragraph of the process of the respiratory system. 4-7 sentences

solong [7]

Answer:

First, you breathe in oxygen through your trachea. The air travels down through the trachea to your lungs. Then your lungs transport the oxygen through your pulmonary artery to your heart. Then the heart transports the oxidized blood throughout your body. Then once the blood gives away all the oxygen your veins take the filtered blood through your pulmonary vein and back to your lungs to get oxidized again. I hope this helps

What contents of the lysosome aids in their digestive function?

Oksi-84 [34.3K]

Digestive enzymes are prolific inside the lysosomes. The organelle is named as such because these enzymes engage in "lysing" activity, meaning that the break up the worn-out cell parts or other wastes that the structure engulfs.
