Question

A nerve signal is like a wave. How does this work?


An electrical wave moves down the axon by electrons moving from the place the signal started to the place it ends up.


A wave of reversal of the negative electrical potential inside the cell passes along the axon with ions moving in and out of the axon.



A wave of movement passes down the axon, in which the whole axon moves sideways in one place and then the next.


The density of the cytoplasm inside the axon changes from one place to the next as the signal moves along the axon.

Answer 1

The answer is B. I just took the quiz and got it right. Hope it's the same thing for you.

Answer 2

I just took the test too and the answer is B.a wave of reversal of the negative electrical potential inside the cell passes along the axon with ions moving in and out of the axon...Trust me...its B...this answer is legit and its right....i always look for a legit and wonder if it is legit but i am telling you that this answer is legit...so the answer is B...ans you have found your legit answer...Your welcome and I know that this will help...cause it is the right answer..#legit
