A scientist observes two cells. Cell 1 and Cell 2 both contain DNA (genetic material) and ribosomes. However, Cell 1 contains a nucleus and other membrane-bound organelles, which Cell 2 does not. What is the correct classification for each of the cells?

• Cell 1 = Eukaryotic, Cell 2 = Prokaryotic

• Cell 1 = Prokaryotic, Cell 2 = Eukaryotic

• Cell 1 = Eubacteria, Cell 2 = Archaea

• Cell 1 = Archaea, Cell 2 = Eubacteria

Based on cell size and complexity, prokaryotic cells would be expected to —

• have more ribosomes than most eukaryotic cells

• have fewer ribosomes than most eukaryotic cells

• be affected more by DNA mutations compared to eukaryotic cells

• be affected less by DNA mutations compared to eukaryotic cells
