PhysioEx 9.0 Lab Manual

Would appreciate some help with my PhysioEx 9.0 Labs. I am currently doing exercise number 3. I know I am only supposed to post two questions, so I will try to divide my questions to minimalize them. Thanks for the help!

Exercise 3, Activity 1
1. Explain why the resting membrane potential had the same value in the cell body and in the axon.
2. Describe what would happen to a resting membrane potential if the sodium-potassium pump transport pump was blocked.
3. Describe what would happen to a resting membrane potential if the concentration of large intracellular anions that are unable to cross the membrane is experimentally increased.
