Which of the following statements does not correctly describe the repolarization of a neuron?
Select one:
a. The potassium ions leave the cell, thereby returning the neuron to its resting potential.
b. The potassium channels are slower to open, allowing the potassium ions to leave after depolarization.
c. The sodium and potassium channels open, allowing the positive ions to move out of the cell.
d. The neuron becomes more polarized and more negatively charged than its original resting membrane potential.

and

Which of the following situations correctly illustrates the All or None Principle?
Select one:
a. A smaller voltage change will result in a smaller nerve impulse.
b. A faster impulse can be generated with a voltage change that is greater than the threshold potential.
c. Greater voltage change and smaller voltage change will result in the same action potential as long as the threshold potential has been reached.
d. A stronger impulse can be generated by increasing the number of open voltaged gated sodium channels during depolarization.
