Eubacteriaudents research unicellular, prokaryotic organisms that live in harsh environments such as volcanic hot springs, brine pools, and anaerobic black organic mud.
Which of these groups are the students most likely researching?

a) Archaebacteria
b) Eubacteria
c) Plantae
d) Protista

The correct option is A

Archae bacteria are extremophiles which thrive in extremely environment.

Explanation:

Extremophiles are organisms that inhabit extreme environments. They thrive in hot niches, ice, and salt solutions. Some of them grow in toxic waste, organic solvents and heavy metals. Extremophiles include members of all domains of life which are bacteria, archea,and eukaryotes. Out of these three members of extremophiles, archea are the main group of microorganisms to thrive in extreme environments. This is because the archea are skilled in adapting to different extreme conditions than bacteria and eukaryotes.

Archea are hyper thermophilic microorganisms.

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
