Key Concepts
-
Cell Theory
- All living organisms are composed of cells.
- The cell is the basic unit of life.
- All cells arise from pre-existing cells.
-
DNA and Genetics
- DNA (Deoxyribonucleic acid) is the hereditary material in organisms.
- Genes are segments of DNA that code for proteins and determine traits.
-
Evolution
- Change in the heritable traits of biological populations over successive generations.
- Mechanisms include natural selection, mutation, genetic drift, and gene flow.
-
Homeostasis
- The ability of an organism to maintain a stable internal environment despite external changes.
Examples of Bio Applications
