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:
The answer is the first option: Since the polar cytoplasm contains information to form germ cells, germ cells would form in the anterior region.
Explanation:
If polar cytoplasm is transplanted into the anterior end of the egg just after fertilization, pole cells will develop there at the anterior end, as much as they would normally develop if they are transplanted to the posterior end of an egg. Usually, Polar cytoplasm is localized at the posterior end of eggs through maternal genes.
