which statement about the biological domains and kingdoms is not true?
bacteria and archaea are both domains and kingdoms.
all organisms in archaea and bacteria are prokaryotes.
archea is divided into four domains.
eukaryotic cells are common to animals, plants, protists, and fungi.
bacteria and fungi serve important functions in humans and ecosystems.
clear my selection

Explanation:

• Option 1: Bacteria and Archaea are domains. In some classification systems, they can also be considered as kingdoms (e.g., in the two - kingdom prokaryote classification within the three - domain system).
• Option 2: By definition, all organisms in Archaea and Bacteria lack a membrane - bound nucleus, so they are prokaryotes.
• Option 3: There are three domains: Bacteria, Archaea, and Eukarya. Archaea is a single domain, not divided into four domains.
• Option 4: Animals, plants, protists, and fungi are all part of the Eukarya domain, so they have eukaryotic cells.
• Option 5: Bacteria (e.g., gut microbiota) and fungi (e.g., decomposers in ecosystems) serve important functions in humans and ecosystems.

Answer:

Archea is divided into four domains.
