Questions: Identify the two domains listed below which contain cells that lack a membrane-bound nucleus? Archaea Eukarya Bacteria

The two domains that contain cells lacking a membrane-bound nucleus are:

1. Archaea
2. Bacteria

Explanation:

• Archaea: This domain consists of prokaryotic cells, which do not have a membrane-bound nucleus. Instead, their genetic material is located in a nucleoid region.

• Bacteria: Like Archaea, Bacteria are also prokaryotic and lack a membrane-bound nucleus. Their DNA is similarly found in a nucleoid region.

• Eukarya: This domain includes eukaryotic organisms, which have cells with a membrane-bound nucleus. Therefore, Eukarya is not one of the domains that lack a membrane-bound nucleus.

In summary, the domains Archaea and Bacteria both consist of prokaryotic cells that do not have a membrane-bound nucleus.
