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.
Homeostasis describes the functions of your body which work to keep your internal environment constant within a very narrow range. Two important aspects of homeostasis are balancing the blood sugar levels and maintaining the body temperature.Your body is made up of millions of cells which need the conditions inside your body to be as constant as possible so they can work properly. However everything you do tends to change your internal conditions.he blood sugar levels in your body are coordinated by hormones, chemicals which regulate and balance the working of organs and cells. Hormones are made in endocrine glands and are carried around the body to their target organs in the blood stream.
