Question 1 • Fall 24 GSE Biology B-IC

Which can modern taxonomy do?

Answer
A
design tables based on physical characteristics
B
compare the length of DNA among members of a species
C
compare the length of RNA among members of a species
D
distinguish how closely related organisms are

Explanation

Modern taxonomy uses evidence such as DNA and other molecular data to infer evolutionary relationships. This lets scientists distinguish how closely related organisms are, making “distinguish how closely related organisms are” the correct choice. Physical characteristics can also help classify organisms, but they are not the defining advantage described here.
