Course Introduction
Biological Science is a comprehensive course that explores the fundamental principles and concepts underlying the study of living organisms and their interactions with the environment. The curriculum covers a diverse range of topics including cell structure and function, genetics, evolution, ecology, physiology, and biodiversity. Students will develop an understanding of scientific inquiry, experimental design, and data analysis while exploring the molecular, cellular, and organismal levels of life. Through lectures, laboratory work, and field investigations, students gain a solid foundation in biological concepts and their real-world applications in fields such as medicine, agriculture, environmental science, and biotechnology.
