Collateral blood flow is an enlargement vessel that opens to cause a detour around a blockage. When an artery in the brain is block (TIA) open collateral vessels can allow blood to bypass the blockage to restore blood flow to the affected area. <span />
The chromosomal mutation in the zygote can be traced back to "Chromosome 6 in the egg cell".
<u>Option: B</u>
<u>Explanation:</u>
In germ cells i.e. egg or sperm cells, the mutations in chromosome often happen during the meiosis phase. The number of chromosomes in egg cells or sperm cells must be haploid, so that diploid chromosomes form zygote on fertilization. Chromosome mutation in meiosis leads in an additional set of chromosomes or structural defects in the chromosome.
Chromosomal mutations are often caused by chemical agents or by mutagens.
The homologous chromosomes are segregated from sister chromatids throughout cell division, any abnormality at this point allows the chromosomes to be unequally divided or not disjuncted, same is observed in the situation seen in egg cell chromosome 6.
The chemical information for making proteins is carried in the DNA, which is found on the chromosomes in the cell nucleus.
As of now Sudbury has some of the cleanest air in all of Ontario. That’s hard to believe given the city once emitted 2.5 million tonnes of sulfur dioxide per year due to the Lumber industry. In the 1980s, the “Sudbury” became known as a unit of pollution, against which other industrial cities were measured. It’s now become known as a unit of restoration.
