Quizplus · Accepted Answer

The lack of a nuclear membrane and presence of methane production are both characteristics commonly found in organisms belonging to Domain Archaea. Additionally, some species of archaea have been found in the rumen of animals, making this classification even more likely. The absence of peptidoglycan in the cell wall rules out Domain Bacteria as an option, and the lack of fungal features rules out Kingdom Fungi and the possibility of Eukarya as a domain.
