Question

A single-celled organism is found living in a deep sea vent at the bottom of the ocean in extremely hot water. If it is examined further, which of the following is most likely to be found within it?. . It will have a nucleus and other membrane-bound organelles since it is likely a member of the domain Eukaryota.. . It will have a cell membrane since it is likely a member of the domain Archaea and the Kingdom Protista.. . It will have DNA and RNA, as well as a cell wall, since it is likely a member of the domain Bacteria.. . It will have DNA that is not contained in a nucleus since it is likely a member of the domain Archaea.

Answer 1

Answer: It will have DNA that is not contained in a nucleus since it is likely a member of the domain Archaea

The domain archaea includes the single celled microorganisms. These microbes are prokaryotic organisms that do not possess nucleus and membrane bound organelles. But contains genetic material in the form of DNA. All organisms of this domain are extremophiles that lives in the harsh environments such as hot springs and salt lakes. The organisms of archeal domain which can live and survive in hot water they are called as thermophiles, whereas those which can live and survive in the saline conditions they are called as halophiles.

On the basis of the above information, it will have DNA that is not contained in a nucleus since it is likely a member of the domain Archaea is most likely to be found within the deep sea vent.

Answer 2

I believe the last option is the correct one for the illustration of the single celled organism provides and the environment that it is found living in.
