The Control
From my previous lab, i'm assuming it's the same, there are 4 tests: monosaccharaide, starch, lipid, and protein. If a sugar cube is to be placed into the unknown solution and then tested by the 4 tests, there would be NO affect: * Note: Some will think that placing a sugar cube into the solution will change the results of the monosaccharaide test, but there won't be. Remember, the monosaccharide only tests positive in the presence of a monosaccharaide, but sucrose is a DISACCHARIDE, so there will be no affect. As for the other tests, they are indicators of starch, lipids, and proteins, again, nothing else. Therefore, sugar has no affect on the results whatsoever.
lipid
No, UTIs do not affect the accuracy of pregnancy tests.

Scientific tests can help determine substances that appear similar but react differently under the same circumstances. By observing the reactions of the substance using an experiment, you can determine what that substance is made from.

A control is a known setup for a given experiment that is known to have no effect on the outcome, that it will remain constant throughout all tests. It is part of a test group that does not change, so as to compare results in the end.
The factor that your results or tests are "dependant" on. As in you could not get the correct experiment without it
