Which of these fields is used to classify organisms? question 3 options: genetics taxonomy anthropology botany

Hello.

Taxonomy is used to classify organisms.

Genetics is is the study of genes, heredity, and genetic variation. This has nothing to do with classifying organisms (yet).

Anthropology is the study of various aspects of humans within past and present societies. (Source: "Wikipedia") As we can tell, this also has really nothing to do with classifying organisms, just studying aspects.

Botany, also called plant science, plant biology or phytology, is the science of plant life and a branch of biology. (Source: "Wikipedia") Given this information, it has nothing to do with classifying organisms, only studying plants.

Based on our definitions and citations, we can safely assume your answer is
"Taxonomy."

I hope this helps!
