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:
All the given statements given about carbon are true.
Carbon is an element which has atomic number 6 and valency as 4. Thus, it can form 4 bonds at a time.
It can satisfy its valency by forming one, two, three, or four bonds at a time with another element including carbon itself.
For example, C₂H₆, C₂H₄, HCN et cetera.
Carbon has a unique property of catenation that is, it can form long chains of interconnected carbon atoms.
