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?

Both can undergo binary fission and are autotrophs.

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

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

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

Answer 1

can you rule any out?

Answer 2

I think that they both can survive extreme temperatures, they both are unicellular, they both reproduce asexually (through binary fission)...

Answer 3

"Both can undergo binary fission and are autotrophs"

are they also autotrophs?

Answer 4

I think that they both are autotrophs...

Answer 5

no, a lot of bacteria (eubacteria) are heterotrophs.

Think about what makes fit into the "prokaryote" category, what makes them different from eukaryotes?

Answer 6

Honestly IDK...

Answer 7

do prokaryotes have a membrane-bound nucleus or membrane-bound organelles, are they ever more than a single cell?

Answer 8

I think that prokaryotes are always single celled. And prokaryotes cells don't have membrane-bound organelles.

Answer 9

yes

Answer 10

So the answer is A??

Answer 11

No, Archea and bacteria both lack membrane bound organelle.

Answer 12

I'm confused now!
