False
Biologists study life at multiple levels of organization, from molecular biology to the anatomy and physiology of plants and animals, and evolution of populations.
True
All organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations.
True
Evolution does not explain the unity and diversity of life.
False

Cellular Structure and Heredity
- All organisms are composed of cells
- Cells process hereditary information encoded in genes
- Genes can be transmitted to future generations
Evolution and Diversity of Life
- Evolution does not fully explain the unity and diversity of life
- Life on Earth emerged over 3.7 billion years ago
- Life on Earth is immensely diverse
