Answer:
The correct answer is - Archaea or archaebacteria.
Explanation:
Archaea is the domain and the kingdom of the single-cell prokaryotic organisms as they lack a nucleus. These organisms are present in extreme habitats such as hot springs, high saline water. These organisms can live in extremely aggressive environments which makes it a uniqe characteristic of this organism.
In the given condition the organism that lives in hypersaline water is most likely a member of the Archaea domain or Archaebacteria kingdom as it is found in the hypersaline waters of Southeastern Australia and unicellular organisms.
The nucleus pretty much controlls all of the cell. Just like the main office controls all of the building
