Prokaryotic cells, contains unique rrna ,live in extreme environments ,cell walls contain no peptidoglycan membranes ,composed of branched hydrocarbon chains- the characteristics listed above describe the domain a) archaea b) bacteria c) eukarya d) monera

The correct answer is: Archaea.

Different domains are based on difference on the rRNA sequences. Archaea are prokaryotic cells that live in extreme environments (such as high temperature or high salt environments), with cell walls that has no peptidoglycan membranes (in contrast to bacteria) and cell walls are comprised of branched hydrocarbon chains. Eukarya are eukaryotic cells. Monera is not a domain but rather a kingdom.
