Answer:

Chromosome 21 in figure D is the result of a process known as non-disjunction

Explanation:

Meiosis is the process of cell division that serves to obtain gametes, cells with exactly half the chromosome load of the species. This process involves the equal distribution of chromosomes in each daughter cell.

Non-disjunction is an alteration in the separation of the sister chromatids during meiosis, resulting in a gamete with non-separated sister chromatids, which when joined to a normal gamete can produce an organism with an extra chromosome.

In the karyotype shown in the photo, the non-disjunction in chromosome 21 produces a trisomy, a type of aneuploidy seen in Down syndrome.

Explanation:

Water pollution is th contamination of water. There are many means through which water is contaminated such as industrial waste, agricultural waste and domestic waste et-cetra.

City A and City B get water from sunset lake and moth lake which have factories (industrial waste) and farmland (agricultural waste) nearby them, which are responsible for the contamination of river water. due to this cities can recieve contaminated water which can affect their health.

But the quality of water in City A will be best than that of City B because according to the image, City A do not have nay upstream soooooource of pollution, as factories and farmland are located at downstream.

Hence, the correct option is A.

nadezda [96]

Answer:

Change in the structure of chromosome.

Explanation:

Chromosome structure mutations are the changes that occur in the structure of chromosomes rather than just individual nucleotides. These mutations occurs due to the errors that happens in cell division that leads to the breaking in section of a chromosome, which can be duplicated or move onto another chromosome. Chromosome mutation is the process of change in the chromosomes that occurs due to the rearranged chromosome parts and  abnormal numbers of individual chromosomes.
