Question

a single-celled organism is found living in a deep sea vent at the bottom of the ocean in extremly hot water. If it is examined further, what is most likely to be examined within it?

Answer 1

how that microbe bear such high pressur? that we can examine.

Answer 2

its probably some sort of bacteria so preety much all the caracteristics of a bacteria: circular DNA, nucleoide, ect

Answer 3

Generally, with questions like these the key word is "deep sea" or "extremely hot." You know, since it's a single celled organism, that we're talking about the prokaryotes - as issyb93 mentioned, they have circular DNA + nucleotides (as well as cell walls, no membrane-bound organelles or a nuclei, etc.) , but to be specific - you may want to differentiate between the two groups of prokaryotes, the eubacteria and the archaebacteria. Extreme conditions, like the ones aforementioned, are associated with the archaea.

Archaea have non-peptidoglycan cell walls, some also have histones in their DNA, and in this case - think about what adaptations are needed to live in this environment. For example, the Taq polymerase is a specialized, heat-resistant DNA polymerase famous for its application in PCR. What else would be needed for the organism to survive?

Sorry to ramble there a little, but apart from that, you would have most of your "regular" prokaryotic characteristics, including ribosomes, proteins, amino acids, carbs, and anything else needed to survive.

Answer 4

Can be a termophile... .-.
