Why do people think that humans and chimpanzees come from a common ancestor? Where is the proof? There is no possible way humans and chimps can mate. Although lions and tigers can.

I can't even understand the question, let alone answer it..any help?thanks!

You are given four 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:
a. Test tubes #2 and #4 contain nitrogen, but the other tubes do not.
b. The contents of test tube #3 are not soluble in water, but the contents of the other test tubes are soluble in water.
c. The contents of test tube #1 can be broken down into subunits that are all exactly identical to each other.
d. The macromolecule in test tube #2 is found to have a globular shape.
What are the identities of the macromolecules present in the four test tubes? Explain how you arrived at your decision.
