Describe the two patterns of metamorphosis that happen in the life cycles of insects. Usr an example of a specific insect to describe the pattern

 The two patterns of metamorphosis that happen in the life cycles of insects are the butterfly and the Dragonfly. The metamorphosis of a butterfly is complete, unlike the dragonfly where they only have 3 stages egg, larva and, adult.

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.
