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.
Close suction drains play very crucial in surgical wound healing. It is important that the wound suction drain works properly because the proper healing of the wound depend on it. If the wound suction drain do not work properly, it will be difficult to obtain accurate recording of the volume and the contents of the drainage that is coming out from the wound. Thus, it will be difficult to monitor for excessive bleeding, infections and things like that which may prevent proper healing.
