ANSWERS AND EXPLANATIONS

---

A) 42 mV

This answer is incorrect.

A human neuron's resting potential is approximately -65 mV. The cell is more electrically negative on the inside of the cell membrane (that is, in the cytoplasm) compared to the outside (the extracellular fluid).  (See References)

C) 115 V

This answer is incorrect.

No, 115 V is the standard voltage in household alternating current sockets in the USA. That's a bit much to expect from a single human cell.  (See References)
