Introduction to Biology Study Guide Questions
Course Introduction
Introduction to Biology provides a comprehensive overview of the fundamental principles that govern living systems. This course explores the structure and function of cells, genetics, evolution, ecology, and the diversity of life forms. Students will gain an understanding of the scientific method, biomolecules, metabolic processes, and how organisms interact with their environments. Emphasizing both theoretical concepts and practical applications, the course lays a solid foundation for further studies in biological and health sciences.
