Which of the following is incorrect about molecular taxonomy?

Molecular taxonomy compares DNA, RNA, and protein sequences.
It helps determine evolutionary relationships between species.
It relies only on external features for classification.
It is useful in identifying microorganisms.
3

Molecular taxonomy is based on genetic and molecular data rather than external morphological features alone.

Which of the following statements about classification is correct?

Classification helps in identifying relationships among organisms.
Classification is only based on physical characteristics.
Classification does not help in biodiversity conservation.
Classification is unnecessary in modern biological studies.
1

Classification helps in understanding evolutionary relationships and organizing biodiversity.

Which of the following statements about taxonomic hierarchy is incorrect?

Genus includes multiple species with similar characteristics.
Order is ranked below Family in the taxonomic hierarchy.
Phylum consists of multiple Classes.
Kingdom is the highest rank in the taxonomic hierarchy.
2

Order is ranked above Family in the taxonomic hierarchy, not below it.
