Question

In the classification of organisms by kingdom, all prokaryotes are grouped together in the kingdom Monera. Genetic research, however, led to the separation of prokaryotes into two domains, Archaea and Eubacteria. Which of the following best describes similarities between Archaea and Eubacteria?
Answer

Both are able to withstand extreme temperatures and lack of oxygen.

Both can undergo binary fission and are autotrophs.

Both have single-stranded, helical DNA and cell walls.

Both lack membrane-bound organelles and are single-celled.

Answer 1

Answer:

D. they both lack membrane-bound organelles and are single-celled

Explanation:

Answer 2

The answer is Both lack membrane-bound organelles and are single-celled.

Prokaryotes are unicellular organisms. The main difference between them and eukaryotes is the absence of nucleus and organelles in prokaryotes and their presence in eukaryotes. That is why they belong to different kingdoms. On the other hands, Archaea and Eubacteria differ in the composition of their cell wall. Archaea's cell walls are made of  uncommon lipids while Eubacteria have cell walls made of peptidoglycan.
