Please Help me I need this

Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.

Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.

Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.

If I wanted to test whole milk using all of the indicators (biuret, benedicts, iodine and brown paper bag), what results would y

stellarik [79]

Whole milk will give a biuret positive, Benedict positive, iodine negative and brown paper bag test positive results.

<h3>Explanation:</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.
