Step 1

Hi ! Thanks for posting the question. Since we are entitled to answer fist question, we’ll answer the question number 1  as you have not mentioned the question number you need help with. Please resubmit the other questions separately, so that our experts can help you. 

Step 2

Depending upon the membrane potential the sodium and potassium ions gated channels are opened or closed.

If the membrane potential is negative, then this means that the internal of the cell is negative with respect to the outside of the cell. 

If the membrane potential is positive, then this means that the internal of the cell is positive with respect to the outside of the cell. 

Step 3

When membrane potential is negative or positive then the ion gated channels are open to maintain the polari...
