Solution
Homeostasis is the maintenance of a constant or unchanging "normal" internal environment during unstressed conditions.
Steady state is also defined as a constant internal environment, but this does not necessarily mean that the internal environment is at rest and normal. When the body is in a steady state, a balance has been achieved between the demands placed on the body and the body's response to those demands.
While homeostasis refers to the entire internal environment, the term steady state can be restricted to describing specific mechanisms. A cell is in homeostasis because every mechanism that keeps it alive is in a steady state. For example, an enzyme complex called sodium/potassium ATPase (also known as the sodium/potassium pump) uses energy from the hydrolysis of ATP to "trade" sodium ions for potassium ions, thus maintaining a constant internal concentration of potassium. Potassium concentration can be said to be in a steady state.
