LIFE SCIENCE

Detailed explanation-1: -Answer and Explanation: The broadest classification level in biology is the first level, which is domain. All living things on Earth belong in one of three domains: Archaea, Eubacteria and Eukaryota. Archaea and Eubacteria are both domains that consist of prokaryotes, or types of bacteria.

Detailed explanation-2: -The three domains are the Archaea, the Bacteria, and the Eukarya. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.

Detailed explanation-3: -Domain is the highest taxonomic rank in the hierarchical biological classification system, above the kingdom level. There are three domains of life, the Archaea, the Bacteria, and the Eucarya.

Detailed explanation-4: -A domain is a larger, more inclusive category than a kingdom. Under this system, there are three domains-domain Bacteria (corresponding to domain Eubacteria), domain Archaea (corresponding to kingdom Archaebacteria), and domain Eukarya (corresponding to kingdoms Fungi, Plantae, Animalia, and kingdom “Protista”).
