In this lab, biology students were directed to use indicators as chemical detection tools, to analyze a variety of foods for the presence of carbohydrates, lipids or proteins. one group of students was given four unmarked containers of sugars: glucose, sucrose, fructose, and galactose. how could they use the standard lab tests to find the sucrose? a) they could use the benedict's test; sucrose would have a positive benedict's test and the other sugars would not. b) they could use the biuret test; it would not have a positive reaction for sucrose but it would for the other three sugars. c) they could use the benedict's test; it would not have a positive reaction for sucrose but it would for the other three sugars. d) they could use the iodine test; because sucrose is not a monosaccharide, it would have a positive iodine test and the others would not.
