Answer:
(d) Cell wall
Explanation:
The cell wall is a structure located on the outside of the cell membrane in the cells of plants, bacteria, fungi, and algae. It is a resistant, tough and flexible layer, which has the vital function of supporting the osmotic pressure inside the cell, preventing the cell from lysis when water enters. Besides, it has the function of giving rigidity, support and defining the shape of the cell.
The RODS detects shades of grey and are responsible for peripheral vision, while the CONES are responsible for colour vision and seeing fine details.
Rod cells are photoreceptor cells that are located on the retina of the eyes. Rods cells are usually concentrated at the outer edge of the retina and they are use in peripheral vision. Cones on the other hand are photoreceptor cells which are responsible for colour vision and they work best in bright light.

Answer:
d. multiple alleles and codominance
Explanation:
ABO blood group is controlled by three alleles instead of the usual two. Hence, it is an example of multiple alleles. These three alleles are IA, IB and i. IAIA genotype leads to production of A antigen hence A blood group. IBIB genotype leads to production of B antigen hence B blood group. When they are present together (IAIB) both A and B antigens are produced resulting in AB blood group. Hence ABO blood group is also an example of codominance.
Both IA and IB are dominant over the i allele. So IAi and IBi will produce A and B blood group respectively. ii genotype leads to O genotype.
