Answer Key / Explanation : (a) -
(a)
In resting nerve fibre (a nerve fibre that is not conducting an impulse), sodium ions (
) predominate in the extra cellular fluid, whereas potassium ions (
) predominate in the intracellular fluid (within the fibre). This result in the fact that, the resting membrane has only a poor permeability for 
although it has a higher permeability for
