Question

what are the three domains of life based on rrna comparisons?

eukarya, archaea, and monera

bacteria, archaea, and eukarya

plantae, animalia, and monera

bacteria, protista, and archaea

Explanation:

This is the standard three-domain system of biological classification established through rRNA sequence comparisons, which distinguishes prokaryotic Bacteria, prokaryotic Archaea, and eukaryotic Eukarya as the highest taxonomic groups of life. The other options include outdated or incorrect taxonomic groups (like Monera, Protista, Plantae, Animalia) that do not fit the rRNA-based three-domain framework.

Answer:

B. Bacteria, Archaea, and Eukarya
