B antibodies binding to a virus
Cprotein synthesis
Dinsulin secretion in response to high blood sugar
E proton pumping to maintain a proper pH level
F flagellar rotation for cell movement

Homeostasis can be described as a tendency of living organisms to maintain a state of stable internal environment. In other words, it is the tendency to resist any change in the optimal conditions for survival.
It is brought by several regulatory mechanisms in the body such as regulation of body temperature, regulation of pH, regulation of osmolarity etc.
