A unicellular microorganism was recovered from a hot spring (95oc) in wyoming. the cells lack a nucleus, have a cell wall that lacks peptidoglycan, and have 70s ribosomes. analysis of the plasma membrane reveals that the lipids contain long-chained branched hydrocarbons with ether linkages. please choose the group in which this organism would be classified, based on the description provided.

Answer 1

The organism belongs to the class Archea, which is a domain and kingdom of single-celled organisms, which lack a nucleus, peptidoglycan layer in the membrane, and bears 70s ribosomes. Archea are prokaryotic and are different from bacteria and eukaryotic organisms.
