The house fly, Musca domestica, has a haploid chromosome number of 6. How many chromatids should be present in a diploid, somati
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.

Answer:

C. Meiosis produces new combinations of chromosomes.

Explanation:

Compared to mitosis, meiosis divides TWICE and has EIGHT stages of rather than mitosis with the regular four stages.

The end result in Meiosis produces haploid cells in which half of the amount of chromosomes are produced in each individual cell, therefore Meiosis produces new combinations of chromosomes.

A. is incorrect because Meiosis does NOT create genetically identical cells.

B. is incorrect because Meiosis creates a HALF set of chromosomes (or just half than the original amount).

D. is incorrect because DNA is not produced during meiosis.

Your patient has recently completed her first round of chemotherapy in the treatment of lung cancer. when reviewing this morning
dimaraw [331]

When there is myelosuppression, the suggestive finding is there is a decrease in the platelets and red blood cells. Also called the bone marrow suppression, myelosuppression is a common side effect of the treatment of chemotherapy. When this side effect happens, there is a decrease in the production of blood cells. The result which may be the effect of myelosuppression is a decrease in one, two or all three types of blood cells. Most patients of chemotherapy experience a decrease in red blood cells. Another effect is the decrease of white blood cells by most patients. Myelosuppression will be subcategorized as neutropenia when chemotherapy results to the reduction of neutrophils which is a specific type of white blood cells. Thrombocytopenia is the term for a drop in platelet numbers. This kind of suppression is not that common.  Only 10 percent of cancer patients undergo the negative effects of this kind of suppression.
