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.
This adjusting of physiological systems within the body is called homeostaticregulation .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.ome of the functions you will learn about inthis book are not specifically about homeostasis (e.g. how muscles contract), but in order for all bodily processesto function there must be a suitable internal environment. Homeostasis is, therefore, a fitting framework for theintroductory study of physiology.
