Question

Which identifies the main purpose of biological taxonomy?
classify organisms by using common names for easy identification of species by scientists
create phylogenetic trees that organize species based only on physical characteristics
use a systematic method to name, organize, and show relationships among species
create common names that can be applied to multiple organisms found in different regions

Answer 1

"use a systematic method to name, organize, and show relationships among species"

Explanation: Biological taxonomy provides a standardized, hierarchical system (including scientific names) to classify organisms and reflect their relationships (often evolutionary). The other choices are wrong because taxonomy uses scientific, not common names, and it considers more than just physical traits when determining relationships.
