👉 Biology, the study of life and living organisms, encompasses the intricate processes that govern growth, development, reproduction, and survival from the molecular level to entire ecosystems. At its core, biology explores how genetic information encoded in DNA directs cellular functions and shapes an organism's traits. From infancy through adulthood, biological systems undergo continuous changes: early life is marked by rapid cell division and differentiation, crucial for development; adolescence involves hormonal surges that drive puberty and physical maturation; and aging, a complex process influenced by genetics, environment, and lifestyle, leads to the gradual decline in physiological functions and increased vulnerability to diseases. Understanding these biological processes is essential for advancing medical science, improving health, and enhancing our overall comprehension of life itself.
