Compare how a cell maintains homeostasis with how the human body maintains homeostasis
grigory [225]
Cells maintain homeostasis by consistently developing energy. Without energy, cells would fall into disorganized, unorderly processes and eventually cell death would occur. Cells also maintain homeostasis through diffusion and the plasma membrane, but regulating substances that enter and leave the cell.

The human body maintains homeostasis through body temperature, hydration, and food intake
