[{'content': 'RMP of the neuron is \nSelect and explain. \nA. -700 V, B. - 7 V, C. -170 mV, D. -70 mV', 'role': 'user'}, {'content': 'Answer: D \nExplanation: Resting membrane potential (RMP) - It is the potential difference between inside and outside of the membrane of a cell at a resting state.\nRMP is maintained by K+ ion. The value for RMP varies for different kinds of tissues.\nRMP of various tissues are given below RMP of a neuron is: -70 mV, RMP of cardiac muscle: —90 mV, RMP of skeletal muscle: -90 mV, RMP of smooth muscle: -50 mV.\xa0Note: RMP is maintained by K+ ion. RMP is close to isoelectric, the potential of Cl–\xa0 Changes in the external K+ concentration affect the RMP Changes in the external Na+ concentration affect the action potential and not the RMP', 'role': 'assistant'}]
