Vlad [161]

Answer:

12

12

24

Explanation:

<em><u>Musca</u></em> <u><em>domestica</em></u> is the scientific name of an animal popularly known as Housefly.  From the question, it is  known that this organism has a haploid chromosome number of 6.

In a diploid chromosomes, the number of chromatids that will be present will be twice of that in haploid.

Since haploid (n) = 6, diploid (2n) will be; 2 × 6 = 12

Somatic cells on the other hand also exhibit diploid number of chromosomes, again it means we will have (2n) = 2 × 6 = 12

In metaphase cell, cells do make sure they complete the S'phase of the cell cycle before cellular division.Therefore, the DNA present in the chromatids in the S'phase actively engage in chromatids doubling, as a result, 24 chromatids (i.e 12 × 2= 24) exists in the metaphase cell.

What type of container is best for protecting the riboflavin content of milk
Arisa [49]

Answer: Cardboard containers are best for protecting the riboflavin content of milk.

Riboflavin or vitamin B2 acts as a coenzyme in the metabolism of flavin mononucleotide and flavin adenine dinucleotide. The riboflavin is destroyed by irradiations and ultraviolet rays and therefore the milk is sold in opaque containers which are stable to heat. The tetra pack used now days is made up of cardboard and best suitable for using as a container to protect the riboflavin content of the milk.
