D) failed homeostasis.

Question

Quizplus · Accepted Answer

The difference in sodium ion concentration between the extracellular and intracellular fluids is an example of chemical disequilibrium. This gradient is maintained by cellular mechanisms like the sodium-potassium pump, which actively transports sodium out of the cell and potassium into the cell, creating a chemical concentration gradient across the cell membrane.
