Aunicellular microorganism was recovered from a hot spring (95°c) 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. choose the group in which this organism would be classified, based on the description provided.

The correct answer is Archaea.

Explanation:

The Archaea constitute a kingdom of single-celled microbes. These microorganisms are prokaryotes, which signifies that their cells are devoid of any cell core, that is, nucleus and other layer bound organelles. The Archaea are the species, which demonstrate the breaking points of life on the planet.  

They were initially discovered and demonstrated in extraordinary circumstances, like earthy hot springs and aqueous vents. They were also found in a distinct scope of overwhelmingly acidic, saline, and anaerobic conditions.
