Butterfly whose tail looks like a head

The correct answer is Hairstreak butterfly.

Explanation:

Hairstreak butterflies come under the family Lycaenidae which have over 30% all butterfly species and are the family members are well known as gossamer-winged butterflies because of the presence of false head on their tail.

Hairstreak butterfly has a false eye and filamentous tail at the wing corner that resembles its antennae present in its head making false head appearance. This phenomenon is called auto-mimicry.

This auto-mimicry is an evolution that protects hairstreak butterflies from their predators like spiders. So the correct answer is hairstreak butterfly.

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.
