Question

question 3
which of the following statements is correct?
o achaea are part of the same domain as bacteria in the classification of life.
o archaea are older organisms than eukaryotes.
o archaea are typically multicellular organisms.
o archaea are made up of eukaryotic cells.

Explanation:

• Domain classification: Archaea and Bacteria are in separate domains. So the statement “Achaea are part of the same domain as bacteria in the classification of life” is wrong.
• Cell type: Archaea are prokaryotes (not made of eukaryotic cells). So the statement “Archaea are made up of eukaryotic cells” is wrong.
• Cellularity: Archaea are typically single - celled organisms. So the statement “Archaea are typically multicellular organisms” is wrong.
• Evolutionary timeline: Archaea are among the oldest forms of life. Eukaryotes evolved later. So the statement “Archaea are older organisms than eukaryotes” is correct.

Answer:

Archaea are older organisms than eukaryotes.
