Vedclass · Answer

(B) The resting membrane potential of a nerve fiber is the electrical potential difference across the cell membrane when the neuron is at rest.This potential is maintained by the unequal distribution of ions (primarily $Na^+$,$K^+$,and $Cl^-$) across the membrane.The typical value for the resting membrane potential in a nerve cell is approximately $-70 \ mV$.Converting this to volts,we get $-70 	imes 10^{-3} \ V = -0.07 \ V$.Comparing this value with the given options,$0.1 \ V$ is the closest order of magnitude.
