The peppered moth population in a locality has light and dark moth varieties. the tree barks in the locality are covered with light-colored lichens. how would the population of the two moth varieties change over time? (3 points) dark moth population increases as they are preyed upon less frequently light moth population increases as they are preyed upon less frequently dark moth population decreases as they blend in with their surroundings light moth population decreases as they blend in with their surroundings

the answer would be b.) the lighter moth population increases as they are preyed on less frequently.

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.
