la verdad no se la repuesta si me la hubiera sabido si te la hubiera dicho
Answer: melanin
Explanation: Further, other cells contribute to the function of the epidermis. Melanocytes are cells that produce melanin, a compound involved in skin pigmentation produced in response to ultraviolet (UV) light exposure (6). Melanin can absorb energy from UV light to shield underlying tissues from damage.
Answer:
Primary consumers
They eat the majority of prey
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.
<span>Diffusion and osmosis
Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration. This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.
Osmosis is the passive movement of water. <span /></span>
