9. The science of classification, organizing and naming living organisms.
12. Any unit of biological classification, including species, genus, family, and so on.
14. A tool used for identification that presents pairs of contrasting characteristics leading to the identification of an organism.
15. Structures in different species that have a similar function but different evolutionary origins.
17. A taxonomic rank below family, grouping species with similar characteristics and genetic relatedness.
18. The study of the diversity of life and the evolutionary relationships among organisms.
19. A taxonomic rank below phylum, categorizing organisms based on shared traits.
20. A rank in the taxonomic hierarchy below class, grouping organisms with similar characteristics and evolutionary relationships.

1. Structures in different species that share a common ancestry.
2. Nomenclature: The system of naming species using a two-part scientific name(genus and species).
4. The study of evolutionary relationships among organisms.
5. A diagram representing the evolutionary relationships among a group of organisms.
6. A method of classification based on evolutionary relationships and shared ancestry.
8. The highest taxonomic rank, grouping organisms into broad categories based on fundamental characteristics.
10. The study of the form and structure of organisms.
11. A taxonomic unit below the kingdom, grouping organisms based on body plan and structural characteristics.
13. The system of naming organisms or the rules and conventions for naming species.
