Study Notes
Unifying Themes in Biology
- The unifying theme in the field of biology is the concept of cells, genetics, and evolution
Composition of Organisms
- The fundamental unit that all organisms are made up of is the cell
Characteristics of Life
- The ability to move, grow, and reproduce are characteristics of living organisms, which are made possible by cellular processes and functions
Levels of Organization
- Biologists study life at various levels of organization, including:
- Molecular level (e.g., DNA, proteins)
- Cellular level (e.g., cell structure, function)
- Organismal level (e.g., anatomy, physiology)
- Population level (e.g., ecology, evolution)
- Ecosystem level (e.g., interactions between organisms and their environment)
Scientific Inquiry
- Biologists use observations and questions to drive scientific inquiry and discovery, often employing the scientific method to test hypotheses and theories
