How are proteins used in mating by japanese beetles?

Males use a protein to detect pheromones sent by females.

Protein work as a chemical signal for the mating.

Explanation:

Pheromones are secreted by the individual of the similar species and they provide signals for communication by releasing a protein substance, they are like alarm substances.

This protein helps to guide females and males so that reproduction can occur.

Females beetles released sex pheromones into the environment, which give a signal of their mating availability.

Then these pheromones are detected by receptors present on the male beetles, and in this way, they find the females for mating .

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.
