Study Notes
Unifying Theme in Biology
- The theory of evolution by natural selection explains both the unity (similarities among species) and diversity (variety of species) of life forms.
Genetic Information Processing
- DNA (deoxyribonucleic acid) within cells encodes hereditary information that is processed to produce proteins through transcription and translation.
Organismal Functions
- Metabolism allows organisms to transform energy and matter, enabling them to move, grow, and reproduce.
Levels of Biological Organization
- Biologists study life at various levels, including:
- Molecular (biochemistry and genetics)
- Cellular (cell biology)
- Tissue (histology)
- Organ (anatomy)
- Organism (physiology)
- Population (ecology)
- Community (ecosystem dynamics)
- Biosphere (global environmental interactions)
Research Methods in Biology
- Biologists utilize observations and the scientific method to propose questions, often employing tools like microscopes, experiments, and field studies for empirical data gathering.
