Mrs. Cortez has asked her students to write an explanation what chromosomes are and what they do. Four student examples are shown. Which student has written the best explanation of chromosomes?

Araceli

Explanation:

I believe this because she just explains it very nicely & if you are to search up chromosomes definition, you'll see that her answer is very identical.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
