Explanation:
Answer:
Visibility
Explanation:
The depth at which an Emperor Penguin can dive is dependent on the extent to which sunlight can penetrate the ice water according to research. The extent of at which light can penetrate the ice water is also dependent on the degree of ice cover on the ocean. As a result of this, <em>as the depth of dive of an Emperor Penguin increases, visibility also decreases as light penetration reduces. In order words, lack of sunlight would reduce visibility as the diving depth of the Emperor Penguin increases.</em> That is why most deep dives have been found to occur in spring time when light penetration is high as a result of sunlight availability.
Answer:
D.Subduction zones are near plate boundaries
Explanation:
Subduction zones are plate boundaries where two plates meet ,one plate is thrust beneath the other.Due to this earthquakes and Volcanic eruptions occurred. this geohazard affects millions of people around the globe, specifically at edge of the Pacific Ocean.This edges consists of many subduction zones. Megathrust is the largest earthquake occurred at the interface between the boundaries of the two plates.
As both the genes get equally expressed in the human blood group genes, both the proteins or characters expressed by those genes get prominent in the phenotype of the organism.
<h3><u>
Explanation:</u></h3>
In case of human blood type, there are co dominance between the genes coding for A blood group and B blood group. Absence of both of them produce the O blood group and presence of both of them produce the AB blood group.
The gene for A blood group codes for enzyme α-1,3-N-acetylgalactosamine transferase which attaches the N Acetylgalactosamine to surface of RBCs which are actually the A antigens.
The gene for B blood group codes for α-1,3-galactosyl transferase which attaches galactose to surface of RBCs which are actually B antigens.
Presence of both of these genes make both N Acetylgalactosamine and galactose to be present on RBC membrane. This is why co dominance occurs in case of AB blood group persons.
