BiologyMultiple Choice
A researcher analyzed four different samples of macromolecules, where all macromolecules in each sample are of the same type. The researcher measured the percent of carbon, oxygen, hydrogen, nitrogen, phosphorus, and sulfur atoms in each sample. The results are shown in Table 1.
Which of the following claims is best supported by the data in Table 1 ?
A) Sample B contains protein.
B) Sample A contains nucleic acids.
C) Sample C contains nucleic acids.
D) Sample D contains protein.

ENone of the above
Explanation:
To determine which claim is best supported by the data in Table 1, we need to analyze the percentages of different atoms in each sample. Looking at the table, we can see that Sample B has the highest percentage of nitrogen atoms (15%), which is a characteristic of proteins. This supports the claim that Sample B contains protein.
On the other hand, Sample A has the highest percentage of phosphorus atoms (10%), which is a characteristic of nucleic acids. This supports the claim that Sample A contains nucleic acids.
Sample C has the second highest percentage of phosphorus atoms (8%), which is also a characteristic of nucleic acids. This supports the claim that Sample C contains nucleic acids.
Lastly, Sample D has the highest percentage of sulfur atoms (5%), which is another characteristic of proteins. This supports the claim that Sample D contains protein.
Therefore, the claim that is best supported by the data in Table 1 is as follows:
A) Sample B contains protein.
B) Sample A contains nucleic acids.
C) Sample C contains nucleic acids.
D) Sample D contains protein.
The correct answer is A. Sample B contains protein.
