Please explain question 10 thoroughly.
Three pigment solutions are given to you. The first pigment, A, contains four -OH and two -NH groups. The second pigment, B, has two-OH groups. The third pigment, C, has a very long hydrocarbon chain with no oxygen. You are told to separate these pigments by paper chromatography using a solvent composed of 70% benzene and 30% acetone. Predict the locations of the three pigments on the paper with respect to the solvent front after they separate. Explain your answer.
The following questions are grade 12 biology questions. Answer the multiple choice questions shown in the photo. Make sure the answer is correct and matches its corresponding letter.
