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

When a neuron is not conducting any impulse,the axonal membrane is comparatively more permeable to $K^+$ ions and nearly impermeable to $Na^+$ ions.

Given below is a diagram of a resting nerve fibre in a polarised state. Select the option which illustrates the correct distribution of $Na^{+}$ and $K^{+}$ ions along the membrane.

During the propagation of a nerve impulse,the action potential results from the movement of

Select the correct sequence of statements regarding the conduction of a nerve impulse and select the correct option given below.
$i.$ Rapid influx of $Na^{+}$ inside the axon.
$ii.$ $Na^{+}$ gates are closed and $K^{+}$ gates open after the refractory period.
$iii.$ Intracellular fluid is electronegative and the potential difference is $-70 \ mV$.
$iv.$ Extracellular fluid becomes electronegative.
$v.$ Disturbance to the resting potential.

When a stimulus is applied to the membrane of a neuron,it causes a rapid influx of
