Answered

The three-domain system classifies life into three domains: Archaea, Bacteria, and Eukarya. Archaea comprises prokaryotic organisms that often inhabit extreme environments and possess unique biochemical and genetic features distinguishing them from bacteria. Bacteria includes prokaryotic organisms with a wide range of habitats and metabolic diversity. Eukarya encompasses all eukaryotic organisms, which have complex cells with membrane-bound organelles and nuclei. This classification system emphasizes genetic relationships and evolutionary history over traditional morphological traits.
