Answer:
The region of retina devoid of photoreceptor cells (rod cells and cone cells)
Explanation:
The retina is the layer of the eyeball and is packed with rod cells and cone cells responsible for night and day vision respectively. The blind spot is the region in the retina where no rod cells and cone cells are present.
Absence of these photoreceptor cells ensures that no vision is formed in this part of the retina. However, the blind spot serves as the site from where the optic nerve passes through the retina and serves to transmit the impulse to the brain.

Answer:
46 chromosomes
Explanation:
Humans are diploid organisms i.e. they contain two sets of chromosomes (each set from each parent). Each set is 23 chromosomes, hence, two sets will be 23 pairs or 46 chromosomes. This means that each somatic/body cell will contain 46 individual chromosomes.
According to this question, DNA was extracted from a cheek cell. If one could magnify the extracted material, there would be 46 individual chromosomes from each of these cheek cells, considering that cheek cell is a somatic cell.
