1. what do we call the naming system of an organism?

Explanation:

1. The earliest biological classification split all life into two groups based on visible traits.
2. This 18th-century scientist created the modern taxonomic framework.
3. Taxonomic levels range from broadest, most inclusive to narrowest, most specific groups.
4. Answers are based on the standard taxonomic hierarchy structure and relationships between levels.
5. These are the three highest, most inclusive groups in modern classification.
6. Answers are based on key cellular and ecological traits defining each domain.
7. These are the major groups below the domain level in modern classification.
8. This is the formal term for the science of classifying organisms.
9. Rules follow the binomial nomenclature standard set by Linnaeus.
10. This is the specific term for the two-part scientific naming system.

Answer:

1. Kingdom Plantae (plants) and Kingdom Animalia (animals)
2. Carolus Linnaeus
3. Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
4. - Contains the most organisms - Domain

• Found above order - Class
• One level smaller than kingdom - Phylum
• Smallest & most specific - Species
• Level smaller than family - Genus
• 2 levels found between domain & class - Kingdom, Phylum

1. Bacteria, Archaea, Eukarya
2. - No Nucleus - Bacteria, Archaea

• Single celled - Bacteria, Archaea, some Eukarya
• May have cell walls - Bacteria, Archaea, some Eukarya (plants, fungi)
• Cells are found in most places - Bacteria, Eukarya
• Complex cells - Eukarya
• Autotrophs/heterotrophs - All three domains (Bacteria, Archaea, Eukarya)
• Single & Multicelled - Eukarya
• lives in extreme environments - Archaea

1. Animalia, Plantae, Fungi, Protista, Eubacteria, Archaebacteria
2. The science of classifying and naming organisms
3. Two words, Italics, Genus category, First letter capital of first word, Species category
4. Binomial nomenclature
