Biological regulation is the process by which living organisms control various internal functions and maintain stability in response to changing external conditions. This regulation is essential for maintaining homeostasis, or the balance within an organism's internal environment. It involves complex interactions between genes, proteins, and other molecules that work together to coordinate and control physiological processes such as metabolism, growth, and immune responses. Understanding biological regulation is important in fields such as physiology, pharmacology, and genetics, as it can help researchers develop new treatments for diseases and improve overall health and well-being.
