what's the difference between a nerve cell at the end of repolarization and a nerve cell in the resting state

The only difference between the end of the repolarization phase and the resting state is that the sodium and potassium ions are on the opposite sides from where they began.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
