Testing for Sugars‚ Lipids‚ Proteins‚ and Starches in Various Samples Introduction The purpose of this experiment is to define and classify macronutrients identify macronutrients in solutions of unknown composition‚ perform chemical testing methods on foods to test for the presence of macronutrients‚ and recognize experimental controls. Nutrients are divided into two categories‚ micronutrients and macronutrients. Micronutrients are required in small quantities and include vitamins and trace

SOFTWARE TESTING SOFTWARE TESTING Testing is the process of executing a program with the intent of finding errors. TESTING PRINCIPLES All tests should be traceable to customer requirements. Tests should be planned long before testing begins. The Pareto principle applies to software testing. Stated simply‚ the Pareto principle implies that 80 percent of all errors uncovered during testing will likely be traceable to 20 percent of all program components. TESTING PRINCIPLES Testing should begin

TESTING FOR MACROMOLECULES Describe the positive test for starch. Explain how you know. The positive test for starch is adding iodine solution. In the experiment‚ the starch solution had the most dramatic reaction with the iodine solution. It turned to an opaque bluish-purple solution while other samples all turned to a colour related to orange and yellow other than the vegetable oil. But the vegetable oil was more translucent than completely opaque. Describe the positive test for
