Life Science
Pre-Test Questions
Course Introduction
Life Science is an interdisciplinary field that explores the structure, function, growth, origin, evolution, and distribution of living organisms. This course provides a comprehensive introduction to the key concepts of biology, including cell theory, genetics, ecology, and physiology. Students will examine the scientific methods used in life sciences to investigate processes at the molecular, cellular, organismal, and ecosystem levels. Through a combination of theoretical knowledge and practical laboratory experiences, learners gain an understanding of the relationships between organisms and their environments, the complexity of biological systems, and the relevance of life science in addressing real-world challenges such as health, sustainability, and biodiversity.
