Study Notes
Unity of Biology
- The unity of biology is based on the shared ancestry of all living organisms and the conservation of genetic information.
- The unity of biology is also reflected in the universal biomolecules, such as DNA, proteins, and carbohydrates, that are found in all living organisms.
Major Themes in Biology
- A major theme in biology that explains the unity and diversity of life is evolution, which describes the change in species over time.
- Evolution explains the diversity of life by describing how species adapt to their environments and evolve into new species.
Cellular Processes
- Energy and molecular building blocks allow organisms to move, grow, and reproduce.
- These cellular processes are essential for the survival and perpetuation of life.
Scientific Inquiry
- Biologists use observations, experiments, and data analysis to make observations and pose questions.
- The scientific method is used to develop and test hypotheses and theories about the natural world.
Levels of Organization
- Biologists can study life at multiple levels of organization, including molecules, cells, organisms, populations, communities, ecosystems, and the biosphere.
- Each level of organization provides a unique perspective on the biology of life.
Cellular Structure
- All organisms are made up of cells, which are the fundamental units of life.
- Cells are the basic structural and functional units of life, and all living organisms are composed of one or more cells.
Homeostasis
- Organisms are able to regulate their own internal environments through a process called homeostasis.
- Homeostasis allows organisms to maintain a stable internal environment despite changes in the external environment.
