Aunicellular 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. choose the group in which this organism would be classified, based on the description provided. protista

Archaea.

Explanation:

The three domains of life are archaea, eubacteria and eukarya. The bacteria and archaea are prokaryotes whereas the eukarya is include in the eukaryotes according to the biological classification.

The archaea are found under the extreme environmental conditions. The nucleus and peptidoglycan layer is absent in archaea and they have 70S ribosomes. They have ether linkages in their plasma membrane structure. The new organism must belong to archaea as it shows all these characteristics.

Thus, the correct answer is archaea.

. fibrinogen is soluble in water and is found in high concentrations in the blood, where it waits until needed to form a clot
