in order to keep a resting membrane potential, the active transport of the sodium and potassium pump must function to keep:
krek1111 [17]

The active transport of the sodium and potassium pump must work to maintain: A high concentration of sodium outside the cell and a high concentration of potassium inside the cytosol in order to maintain a resting membrane potential.

Active transport in cellular biology refers to the movement of molecules or ions across a cell membrane against the concentration gradient from a location of lower concentration to a region of higher concentration. Cellular energy is needed for active transport to achieve this movement.

The electrical potential differential across the plasma membrane of a cell during its non-excited condition is referred to as the resting membrane potential of the cell. The value of the electrical potential difference inside a cell compared to the extracellular environment is often used to indicate the difference across a cell membrane.

Okay. About 71% of the Earth's surface is water. And salt water holds about 96.5% of all the Earth's water. The remaining 3% of freshwater is found in Glaciers and ice caps making it difficult to use because it is frozen. Other places freshwater can be found is: Lakes, swamps, rivers and the atmosphere. I hope this helps!
