Explanation:

Benedict's Test is can be used to detect simple carbohydrates. The Benedict's test can detect reducing sugars (monosaccharide's and some disaccharides), having free ketone or aldehyde functional groups.

The Biuret Test shows the presence of peptide bonds, which are the basis for proteins. These bonds makes the blue Biuret reagent turn purple. The rest is carried out by adding an equal amount of NaOH to a solution of the food, mix carefully and add a few drops of 1% CuSO4, without shaking the mixture.

Lipids form a translucent stain on paper while starch/glycogen turns I2/KI solution blue-black

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
