Biology is the study of life, from the molecules inside cells to the diversity of organisms and ecosystems. This book begins with the chemical and molecular basis of life, then explores how cells function, use energy, and transmit genetic information. It also examines how organisms develop, evolve, and interact with their environments, and introduces key tools in biotechnology, medicine, and scientific research. Together, these units offer a concise overview of how life operates at every level.
