Study Notes
Unity and Diversity of Life
- The primary theme that explains the unity and diversity of life is the shared ancestry and evolution of all organisms.
Levels of Organization
- The molecular level of organization allows biologists to study the molecular biology of a cell.
Hereditary Information
- The primary unit that encodes hereditary information in organisms is the gene.
Scientific Method
- Biologists use the scientific method to make observations, pose questions, and form conclusions.
Origin of Life
- The primary form of life that emerged more than 3.7 billion years ago on Earth is prokaryotic cells.
Energy and Life Processes
- Energy is important to life as it allows organisms to move, grow, and reproduce.
Biological Composition
- All organisms are made up of cells that process hereditary information encoded in genes.
Organismal Level
- Biologists study the anatomy and physiology of plants and animals at the organismal level of organization.
