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.
11. Homeostasis is the body process that attempts to maintain balance of internal environment variables such as pH, temperature, and blood sugar levels because cells and organs function properly in only a narrow range of conditions. 12.All cells have a cell membrane.he body attempts to maintain internal temperatures within this range though the process of homeostasis. However, in cases of exposure to extreme heat or cold, the homeostatic balance is disturbed, and cell die-off, organ damage, or even death can result. 2.
