<em>tube 2: Lactose</em>
tube 3: Insulin
tube 4: RNA
tube 5: Lysine
Explanation:
tube 1: Fat is always not compatible with water it means hydrophobic
tube 2: For rejection of the other tubes the last molecule to assigned a tube is lactose due to we do not have a specific test information for tube 2
tube 3: The insulin has a two disulfide bonds and is the only molecule with sulphur atoms.
tube 4: The nitrogen based compounds that belongs to the RNA are binded with phosphate groups all around its chain, so the presence of phosphate indicates that is RNA.
tube 5: Because was the only one who does not hydrolyse it is an aminoacid.
finally it says that in the tubes 3, 4 and 5 has nitrogen, the only 3 compound with nitrogen are Lysine, insulin and RNA.
