The answer is d. The population of light-colored moths decreased and the population of dark-colored moths increased.
<span>Peppered moth color variation is a good example of natural selection. During the Industrial revolution, due to pollution, trees become darker in the urban area. Light-colored moths were, thus, easy prey. The dark-colored moths were able to camouflage on dark trees and avoid predators. The phenomenon is known as industrial melanism. So, in polluted urban areas, the number of dark-colored peppered moths increased. In the clean environment, were much effective in hiding from predators and they outnumbered the dark-colored moths.</span>
If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.
Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.
The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.

The right options are;
A.The population of pink katydids will decrease.
B.The population of green katydids will decrease.
What will eventually happen to the population of the katydids is that the population of both the pink and green katydids will decrease. The predators which are the birds that feeds on the katydids (prey) will negatively influence the size of the prey populations by reducing them.
Answer:
Homology
Explanation:
Homology refers to the presence of similar or shared body structures, body parts, gene sequences, proteins, etc. among various lineages. It represents divergent evolution of these lineages from a common ancestor.
Presence of various similar structures in human and salamander reflects the fact that these two species have shared a common ancestor during their evolution. The shared ancestry between human and salamander led to the presence of various homologous body parts and identical gene sequences in them.
