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 is the regulation of conditions in the body such as temperature, water content and carbon dioxide levels. Diabetes is a condition where the body cannot regulate its blood glucose levels. <. >. 1. 2. 3.
