A kitten has mostly gray fur, but there are patches of white fur around its eyes, ears, and belly. Neither of the two parents of the kitten have any white patches. Use your model to explain how genetic variations, such as fur patterns, can result from meiosis.

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.

the match lol

hope it mark me as brainlieast.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
