Question

Which of the following statement provides the weakest supporting evidence for the idea that all organisms on earth share a common ancestral origin of life?

• A. All cells on Earth contain cytoplasm.
• B. All cells on Earth are capable of metabolizing glucose using the process of glycolysis.
• C. The DNA of all cells on earth is composed of different combinations of the same 4 nucleotide bases.
• D. All cells on Earth use DNA as their genetic material.

Answer 1

Answer: (B)

All cells on Earth are capable of metabolizing glucose using the process of glycolysis.

Even though the statement holds true for most of the prokaryotic and eukaryotic organisms. The existence of a certain number of prokaryotes, that utilize oils for their energy requirements, some use Sulphur while others oxidize Hydrogen to meet their energy requirements.

So, the correct answer is 'All cells on Earth are capable of metabolizing glucose using the process of glycolysis'
