I found the missing choices:
A. Mitochondria are typically above 50 microns in size, whereas
eukaryotic cells are typically smaller than 10 microns.
B. Mitochondria contain multiple linear chromosomes similar to those
found in eukaryotic cells.
C. Eukaryotic cells appeared on Earth around 1.5 billion years ago,
whereas chloroplasts appeared on Earth only 2.5 million years ago.
D. The 70S ribosomes of chloroplasts are more similar to the 70S
ribosomes found in prokaryotes than the 80S ribosomes found in
eukaryotes.
The correct answer is D. <span>The 70S ribosomes of chloroplasts are more similar to the 70S ribosomes found in prokaryotes than the 80S ribosomes found in eukaryotes.
