A membrane potential that starts at -70 mV and goes to -90 mV would be:

A.
Repolarized

B.
Hyperpolarized

C.
After-hyperpolarized

D.
Depolarized

So -70 mV is resting potential. If it’s decreasing even more, that would be hyper-polarization. And then it would go into something called “refractory period” which I’m assuming is named “after-hyperpolarizarion”

The answer is B, I think.

A membrane potential that starts at -70 mV and goes to -90 mV would be A. Repolarized.

Repolarization refers to a change within a cell. In such a case, the cell undergoes a shift in electric charge distribution. This then leads to more negative charge inside the cell when it's compared to the outside.

In the question given, the membrane potential starts at -70 mV and goes to -90 mV. This shows that there was an increase in the negative value. Therefore, the correct option is Repolarized.
