In the depolarization step of action potential where the membrane resting potential is reversed by the rush of sodium ions into a neuron.

A membrane potential shift from -70mV to +30mV for a limited period of time is known as an action potential.

The moving action potential has three stages:

1) The depolarization step, where sodium ions rush into a neuron and reverse the membrane resting potential; and

2) repolarization, which is a mechanism that restores the resting voltage of the membrane and the ionic concentration in the cell, is caused by the closure of the voltage-gated sodium channels and the opening of the potassium channels.

3) Hyperpolarization, when excessive potassium ion efflux occurs as a result of some open potassium channels increasing potassium permeability and causing a drop in the membrane potential.

4) The action potential, which is a transient reversal of membrane potential that travels through the axon, comprises three phases that are described above.

Which is a correct statement about mutation?
leva [86]

Answer: B: Mutation increase variety in a population.

Explanation:Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.
