Study Notes
Unifying Themes in Biology
- A unifying theme in biology is the concept that explains the unity and diversity of life, highlighting the shared characteristics and differences among all living organisms.
Organization of Life
- The fundamental unit of life is the cell, which is the basic structural and functional unit that all organisms are made up of.
Biological Processes
- Organisms are able to move, grow, and reproduce due to the presence of cellular structures and processes that facilitate these functions.
Levels of Organization
- Biologists can study life at various levels of organization, including:
- Organismal level
- Organ system level
- Tissue level
- Cellular level
- Molecular level
Scientific Inquiry
- Biologists use observations and questions to make sense of the natural world and to develop hypotheses and theories.
- Observations are used to collect data, while questions are used to guide further inquiry and experimentation.
