Course Introduction
Principles of Biology Practice Exam
Principles of Biology provides an introduction to the fundamental concepts and processes that underlie all living organisms. Topics include the structure and function of cells, genetics, mechanisms of evolution, diversity of life, and basic principles of ecology. Emphasis is placed on understanding how living systems interact at molecular, cellular, organismal, and ecosystem levels. The course also explores the scientific method, experimental design, and the application of biological principles to real-world issues such as health, biotechnology, and environmental sustainability.
