Classify each label into the proper domain. This prokaryotic domain is most closely related to domain Eukarya. Organisms consist of cells with a nucleus and other membrane-bounded organelles. Organisms in this domain were the first to produce O_2. These prokaryotes are often found in “extreme” environments. All three domains arose from a common ancestor; this domain was the FIRST to appear. Endosymbiont theory proposes an explanation for how this group of organisms arose.
