In a neuron,the absence of which of the following is observed in response to different types of stimuli?

The rate of conduction of impulses in the motor nerve of a mammal is: (in $, m/s$)

The potential difference in the membrane,which is responsible for the conduction of an impulse,is brought about by a change in the membrane:

At the site of stimulation,the charge of the inner and outer surface of the membrane becomes reversed due to:

What is the value of the resting membrane potential in a neuron (in $, mV$)?

Assertion: The imbalance in concentration of $Na^+$,$K^+$ and proteins generates resting potential.
Reason: To maintain the unequal distribution of $Na^+$ and $K^+$,the neurons use electrical energy.
