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.
Why is homeostasis important to organisms? A: By maintaining homeostasis, organisms remain healthy, strong and stable, with protection from the attacks of foreign organisms, such as viruses, bacteria and fungi. Homeostasis enables organisms to remain balanced while living in constantly changing environments.
