You are given 4 test tubes containing purified biological 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
Test tube #3 is not soluble in water, but the other tubes are soluble in water
The contents of tube #1 can be broken down into monomer subunits of C, H, and O in a 1:2:1 ratio
Test tube #4 contains phosphorus, but the other tubes do not

Based on the data you collected choose the correct identity of each test tube.
