Which of the following membrane parts could be involved the movement of a small hydrophilic molecule? Question 3 options:

1) phospholipid

2) cholesterol

3) glycolipid

4) enzyme

5) transporter

6) glycoprotein

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.

i am sorry but i need more information and a picture.

linnaeus is the father of taxonomy, which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
