What are the 6 Kingdoms? | 1. Bacteria
2. Archaea
3. Animalia
4. Plantae
5. Fungi
6. Protista |
How are Adaptations different from Variations? | Adaptations= Advantage
Variations= Change |
What are 3 examples of Fungi? | Mushrooms, molds, and yeasts |
What is unique about the kingdom Archaea? | They can live in extreme environments. |
