Whole milk will give a biuret positive, Benedict positive, iodine negative and brown paper bag test positive results.
<h3><u>Explanation:</u></h3>
Whole milk is obtained from mainly the dairy animals like cow, Buffalo etc. It contains different ingredients of diet and is considered as an ideal balanced diet for infants.
The Benedict's test is a test to identify the presence of reducing sugars. Milk contains reducing sugar lactose. This is why milk gives Benedict's positive result.
Biuret test also gives positive result because it is a test for protein and milk contains enough of this. The protein in milk is called casein.
The brown paper bag test is a test for lipid and its positive because the milk contains enough lipid. It depends on milk source.
The iodine test is a test for starch and milk isn't a good source of starch. So iodine test isn't positive.
