Study Notes
Definition and Scope of Biology
- Biology is the scientific study of life, a natural science with a broad scope.
Unifying Themes in Biology
- All organisms are composed of cells that process hereditary information encoded in genes, which can be transmitted to future generations.
- Evolution is a major theme that explains the unity and diversity of life.
- Energy processing is essential for life, enabling organisms to move, grow, and reproduce.
- All organisms have the ability to regulate their own internal environments.
Levels of Organization in Biology
- Biologists study life at multiple levels, from the molecular biology of a cell to the anatomy and physiology of plants and animals.
- The evolution of populations is also a level of organization in biology.
Subdisciplines in Biology
- Multiple subdisciplines exist within biology, each defined by research questions and tools used.
Scientific Method in Biology
- Biologists use the scientific method, making observations, posing questions, and seeking answers.
