Action potential is a mechanism of transfer of ions across the plasma membrane down their elctrochemical gradient. Action potential is regenerated by the influx of ions such as sodium in case of voltage gated sodium channels. The voltage gated channels can be either open or closed depending on the action potential. Depolarization of membrane leads to the opening of these channels that allow the sodium ions to enter the cell down their electrochemical gradient. The threshold of action potential is reached when the entry of sodium ions out reach the exit of potassium ions from the cell. This leads to the generation of action potential.
I'm not sure, but I think It's in the middle of the directions
Answer: i think A
Explanation: the thyroid uses the calories so an overactive thyroid would use those calories more quickly, causing the person to lose energy and feel tired.
Answer:
glycolysis. Producers, such as those that make the foods that are shown below, make ATP during the process of photosynthesis.
A punnet square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. The diagram is used by biologist to determine the probability of an offspring having particular genotype. Base on that the possible answer would be that the<span> two parents should have genotype a of something like XXi x XY where Xi is the allele for red eye colour</span>
