Answer:
The correct answer will be option-B.
Explanation:
Viral polymerases are the enzymes which play an important role in the viral genome transcription and replication.
Retrovirus is the single-stranded RNA viruses which replicate through a DNA intermediate and therefore requires the <em>RNA-dependent DNA polymerase or reverse transcriptase</em>. Reverse transcriptase encodes DNA from the strand of RNA which can be replicated and helps in the reproduction of the virus.
Thus, option- B is the correct answer.
The hawk, a carnivore (animal meat-eater), is predating on the rabbit, an herbivore (plant-eater). So the hawk can be seen as the predator and the rabbit as the prey.
But another type of relationship important in Ecology is consumers. So producers are the plants that feed a food web. That makes the rabbits the primary consumers (herbivores) of these plants. Then the hawks become the secondary consumers (carnivores) of the primary consumers, by eating the herbivores.
Hope that this makes sense!
The answer is A. G1 phase -DNA replication
<span>The answer depends of the kind of non-randommating. If the non-random mating is the kind of positive assortative mating then it tends to increase the frequencies of homozygous genotypes. Positive assortative mating when individuals mate with other individuals like themselves. If the non-random mating is the kind of negative assortative mating, then the effect is the opposite as of the positive assortative mating, this is it tends to decrease the homozygous genotypes.</span>
