which of the following statements concerning cells of bacteria and archaea is correct?
○ archaea contain small membrane-enclosed organelles; bacteria do not.
○ chromosomes in both archaea and bacteria contain dna.
○ mitochondria are present in some bacteria and all archaea.
○ archaea contain a membrane-bound nucleus; bacteria do not.

Explanation:

Both archaea and bacteria are prokaryotes, meaning they lack membrane-bound organelles (including nuclei and mitochondria). Their genetic material is stored in chromosomes composed of DNA, which is a shared characteristic of all cellular life forms. The other options are incorrect: archaea have no membrane-enclosed organelles, neither group has mitochondria, and neither has a membrane-bound nucleus.

Answer:

B. Chromosomes in both archaea and bacteria contain DNA.
