Anaerobic prokaryotes use to obtain energy. archaea and eubacteria are prokaryotic in nature. one of the differentiating characteristics between them is that eubacteria have in their cell walls.

The correct answer would be fermentation and peptidoglycan.

Explanation:

Anaerobic prokaryotes perform fermentation to get energy. Fermentation can be defined as a metabolic process, which includes the breaking of large organic molecules into simple molecules in the absence of oxygen.  

Thus, the correct answer is fermentation.

The cell wall of archaebacteria is build of polysaccharides and proteins whereas the cell wall of eubacteria is made up of peptidoglycan molecules. Peptidoglycan is not present in the cell walls of archaea.

Thus, the correct answer is 'peptidoglycan.'

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
