Answer:
Domains
Explanation:
Living organisms are divided into three domains:
Archaea
Eubacteria
Eukarya
Organisms are divided into these three domains based on genetic similarities or closeness. Archaea and Eubacteria are domains that consist of prokaryotes or prokaryotic cells.
Prokaryotes in the domain Archaea differ from those in Eubacteria because of certain characteristics like their ability to live in extreme environments and the absence of the peptiglycan in their cell walls.
Prokaryotes in the Eubacteria domain have peptidoglycan walls and RNA unique to them.
Organisms uner Eukarya, as the name suggests, have eukaryotic cells meaning the have an enclosed or membrane-bound nucleus.
