Study Notes
The Study of Biology
- Biology is the scientific study of life
- It is a natural science with a broad scope and unifying themes
- All organisms are composed of cells that process hereditary information
- Evolution explains the unity and diversity of life
- Energy processing is crucial for movement, growth, and reproduction
- Organisms can regulate their internal environments
- Biologists study life at various levels of organization
- There are multiple subdisciplines within biology
- Each subdiscipline is defined by its research questions and tools
- Biologists use the scientific method for observations and questions
- They study molecular biology, anatomy, physiology, and evolution
- The scientific method is used for making observations and posing questions
