| What is taxonomy | A systematic process of classifying living organisms into different groups based on their physical traits and genetic relationships |
| What is taxonomic name for modern humans | Homo sapiens |

| What is binomial nomenclature | Where organisms are commonly referred to according to the most specific taxonomic level |

| What are the characteristics that every organism in the domain archaea share | They are similar to bacteria, but they have a cell wall but with a different composition compared to the domain bacteria, have unusual lipids in the cell membrane that are found in no other organism on earth, and are thermophiles |
| What are the characteristics that every organism in the domain eukarya share | Most are multi-cellular, they have a nucleus, and membrane-bound organelles |
| What are the 4 kingdoms of Eukarya | Protista, Plantae, Fungi, and Animalia |
| What are 2 modes scientists used to identify and classify organisms | Dichotomous Keys and cladograms |
