DNA has a negative charge because of the phosphate ions in its chemical backbone.
Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector. The receptor receives information that something in the environment is changing. The control center or integration center receives and processes information from the receptor.
The Importance of Homeostasis. Among the most important features of the human body that we must be aware of is homeostasis. Homeostasis is not a collection of organs, but a synthesis of bodily functions that collectively keeps the entire body stable. In order to keep homeostasis at optimum it must have access to adequate supply of energy. Our bodyâs energy comes from the sun.
