Question

an organism has the following characteristics: cell wall, heterotrophic, unicellular, and prokaryote. what kingdom does it belong in?
○ animalia
○ protista
○ plantae
○ eubacteria

Explanation:

1. Analyze Animalia: Organisms in Animalia are eukaryotes, multicellular (usually), heterotrophic, and lack a cell wall. The given organism is prokaryotic and unicellular, so not Animalia.
2. Analyze Protista: Protists are eukaryotes (have a nucleus), can be unicellular or multicellular. The given organism is prokaryotic (no nucleus), so not Protista.
3. Analyze Plantae: Plants are eukaryotes, multicellular (usually), autotrophic (most), and have a cell wall. The given organism is prokaryotic, unicellular, and heterotrophic, so not Plantae.
4. Analyze Eubacteria: Eubacteria are prokaryotes (no nucleus), unicellular, can have a cell wall, and many are heterotrophic. This matches the characteristics of the given organism (cell wall, heterotrophic, unicellular, prokaryote).

Answer:

D. Eubacteria
