Final answer:
The resting membrane potential for most cells falls between -60mV and -90mV, with -70mV being a commonly referenced value, which is important for responding to chemical and electrical signals.
So, the correct answer is B. -60mV and -90mV.
Step-by-step explanation:
Most cells have a resting membrane potential that is typically between -60mV and -90mV, with -70 mV often used as a standard reference point. The resting membrane potential arises due to differences in ion concentrations of ions like potassium (K+) and sodium (Na+) across the cell membrane and the selective permeability of the membrane to these ions. This potential is crucial for the physiological response to chemical and electrical signals, especially in nerve and muscle cells.
In terms of the choices provided, the correct option for the range of resting membrane potential for most cells is B. -60mV and -90mV as it is the range that includes the standard -70mV value typically referenced.
