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

Most prokaryotes, I think, have the best ability to live in extreme conditions. If you take this into consideration, what kind of organisms are most likely to be prokaryotes—more specifically, extremophiles?

Answer 2

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

Step-by-step explanation:

Living organisms have been grouped into a large group called DOMAIN. The domain consists of three set of organisms classified mainly based on their possession of a membrane bound nucleus. The three domains are: Eukarya, Archaea, and Bacteria.

According to the question, a single-celled organism found living in a deep sea vent at the bottom of the ocean in extremely hot water is most likely to be a ARCHAEAN. Archaea members are adapted to living in extreme regions of the earth e.g highly cold and hot temperatures. Hence, if this organism is an archaean, it will be prokaryotic (a similar characteristics with domain bacteria). Prokaryotic organisms are so named because they lack a membrane bound nucleus that harbors their genetic material (DNA).
