Yоu аre given fоur test tubes cоntаining purified biologicаl macromolecules. The test tubes are unlabeled except for a number between 1 and 4. You are told that one test tube contains a protein, one contains a lipid, one contains a carbohydrate, and one contains a nucleic acid. You then perform some tests on the macromolecules and collect the following information:- Test tubes #2 and #4 contain nitrogen, but the other tubes do not.- The contents of test tube #3 are not soluble in water, but the contents of the other test tubes are soluble in water.- The contents of test tube #1 can be broken down into subunits that are all exactly identical to each other.- The macromolecule in test tube #2 is found to have a globular shape.- Test tube #4 also contains phosphorus. What are the identities of the macromolecules present in the four test tubes?
