Final answer:
Starch hydrolysis and lipid hydrolysis are laboratory tests used to detect the presence of carbohydrates and fats, respectively.
Step-by-step explanation:
Starch hydrolysis and lipid hydrolysis are two laboratory tests for the presence of carbohydrates and fats, respectively. In the starch hydrolysis test, iodine solution is added to a starch solution, and the formation of a blue-violet color indicates the presence of starch. In the lipid hydrolysis test, a change in the appearance of the medium is observed when lipids are hydrolyzed.
