Question

scientists group organisms into three domains: archaea, eubacteria, and eukarya. in which domain are animals classified and why? a. archaea, because animals live a long time b. eukarya, because animal cells contain genetic information inside of nuclei c. eubacteria, because animals make their own food d. eubacteria, because animals have one cell

Explanation:

Animals are multicellular eukaryotes. The domain Eukarya includes all organisms with eukaryotic cells (cells that have a nucleus containing genetic information). Archaea are prokaryotes often found in extreme environments. Eubacteria are also prokaryotes. Since animals have eukaryotic cells (with nuclei housing genetic info), they belong to Eukarya.

Answer:

B. Eukarya, because animal cells contain genetic information inside of nuclei
