Which cell process occurs only in organisms that reproduce sexually

MEIOSIS is that cell process that only occurs in organisms that reproduce sexually.

Explanation:

Eukaryotic organisms are the type of organisms that have have  nucleus and other membrane bound organelles. In complex eukaryotic organisms, sexual reproduction takes place. Through the process of meiosis, the production of gamete or reproductive cells i.e the sperm or egg takes place.

Meiosis produces four daughter cell from a single parent cell. each of the daughter cell is haploid. haploid means containing half the number of the chromosomes as the original parent cell.

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.
