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.
Answered by The Community. Making the world better, one answer at a time. A homeostatic mechanism is the property of a system, either open or closed, that regulates its internal environment and tends to maintain a stable, constant condition.For example: the hypothalamus (which is a homeostatic mechanism) senses when your body's temperature is too high or too low. Homeostasis is a term used that refers to the ability of an organism to maintain a relatively stable internal environment so that it can carry on all its metabolic proce â¦ sses to sustain life. If you did not have proper homeostasis, you would die.
