Question

A microbe has been found in the boiling hot waters of a deep ocean hydrothermal vent. It cannot be readily stained or cultured in the laboratory before its rRNA can be sequenced. Wh hypothesis can you offer regarding its identity? a. Fungus b. Bacterium C. Archaea d. Algae

Answer 1

Ans- Archaea and bacteria are both single-celled prokaryotic microorganisms, but the Archaea domain microorganism cell wall does not contain peptidoglycan. Archae often live in extreme environments conditions like hot deep-sea vents, cold antarctic oceans, high salt concentration. The rRNA sequence of archaea is closer to eukaryotes than bacteria.

So in this question, microbes found in hot boiling water of the deep ocean hypothermal vent, the possible microbe is Archaea. Archaea cell wall does not contain peptidoglycan, so it's difficult to stain.

the correct o option C Archaea is the right answer
