Answer:
-70 mV.
Explanation:
The membrane potential is important for the generation of action potential. This helps in the transmission of signals in the body and helps in the communication.
As the cells is in the resting membrane potential, Marcus recording shows the -70mV. The cells at the resting membrane potential has the membrane potential with -70mV. This potential is maintained due to the leaky voltage gated potassium channels.
Thus, the correct answer is -70mV.
