Principles of Biology Exam Preparation Guide
Course Introduction
Principles of Biology introduces students to the foundational concepts of biological science, exploring the structure and function of cells, genetics, evolution, and the diversity of life. The course emphasizes an understanding of how living organisms interact with each other and their environment, as well as the molecular and cellular processes that underlie life. Through lectures, laboratory experiments, and discussions, students gain insights into the scientific method, develop critical thinking skills, and build a strong basis for advanced study in the biological sciences.
