Which is a characteristic of something in the domain archaea?

a.) membrane-enclosed organelles
b.)no cell nucleus
c.) cannot live in extrememe enviorments
d.)multicellular

The correct answer is  B) No cell nucleus.

Archaea is a domain that comprises of single celled microorganisms, which are prokaryotes. These organisms can survive in extremely harsh conditions like hot springs and salt water.

Example- Methanogens.

Archea was first classified as a separate group of prokaryotes under the three domain classification system of Carl Woese in 1977 that included Archaea, Bacteria, and Eukarya.

Since they are a group of prokaryotic organisms, therefore, they are devoid of nucleus and membrane bound cell organelles.

Thus, option B) is the right answer.
