An analysis of a cell indicated a high lipid content in the membranes, a high protein content in the vesicles being mobilized and
transported throughout the cell, and a high carbohydrate content within the cytoplasm. The researcher performing the analysis
concludes that the compounds must serve different roles in the cell. However, a chemical analysis of these three compound types
is also performed. Which comparison BEST illustrates the similarity and difference in the elemental makeup of these molecules?
A)
