Resting membrane potential is negative because a-sodium ions are always leaking out the cell b-sodium ions are always leaking into the cell c-potassium ions are always leaking into the cell?

None of the answers are factually correct but considering that during a resting membrane potential the interior of the cell membrane is slightly negative (~-70mV) and that both sodium and potassium ions are positively charged, the only answer that would be plausible is when a positively charged ion leaves the cell so your best answer here would be "a."

During an action potential hyperpolarization beyond more negative to the resting membrane potential is primarily due to?
Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.
Why the resting membrane potential of erythrocyte is more negative?
it isnt, it is less negative!
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
What about a cell's resting membrane potential is FALSE?
The resting membrane potential is maintained by solely by passive transport processes.
The electrical charge resulting from the difference between the positive and negative ions outside and?
The resting membrane potential
If a resting potential becomes more negative what happens to the cell?
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
During an action potential hyperpolarization beyond more negative to the resting membrane potential is primarily due to?
Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.
Why the resting membrane potential of erythrocyte is more negative?
it isnt, it is less negative!
_____ is the process by which the neuron regains its negative resting membrane potential?
Repolarization
Why is the resting potential value of a membrane negative?
The resting membrane potential is the difference between the inside of the cell relative to the outside. The outside is always taken as 0mv. The resting membrane potential is negative because there is a higher concentration of potassium ions outside the cell (because the membrane is more permeable to potassium ions) than inside. Since potassium ions are positively charged this leads to a negative value.
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
What is a nerve membrane at rest called?
When the neural membrane (neurolemma) is at rest it is said to have resting potential, polarized, and has a negative charge inside.
What about a cell's resting membrane potential is FALSE?
The resting membrane potential is maintained by solely by passive transport processes.
The electrical charge resulting from the difference between the positive and negative ions outside and?
The resting membrane potential
Term that refers to a membrane potential of about -70 mv?
Resting membrane potential
What does the difference in the K and Na concentration on either side of the plasma membrane and permeability of the membrane to those ions generate?
resting membrane potential
