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.
Not to be confused with hemostasis. Homeostasis or homoeostasis (homeo- + -stasis) is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant.Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH).It is a process that maintains the stability of the human body's internal environment in response to changes in external conditions.xamples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH).
