In a resting state, sodium (Na ) is at a higher concentration outside the cell, and potassium (K ) is more concentrated inside the cell. During an action potential, the sodium levels <u>increase </u>inside the cell.
During an action potential, the potassium level inside the cell decreases, and the sodium level inside the cell increases. That is to say, there is an outflow of potassium and an inflow of sodium ions.
Action potential usually occurs when an electrical signal disrupts the balance of Na+ and K+ within a cell membrane, briefly depolarizing the concentrations of each.

The given statement is False, it should read, "A theory and a law are already both supported by evidence and are equal, but they have different functions."
In the scientific method, a "Theory" and a "Law" are already both supported by evidence, but they serve different purposes.
The role of "Theory" in the scientific method is to provide a justification for the data collected through observations and results. As more data is gathered, it may be altered, enhanced, or even dismissed. While a "law" typically refers to an observed natural event that is true no matter how it is tested. It doesn't explain why the incident or event actually happened.
