Energy. It allow the plant or animal to make cellular respiration happen.
Gills enhance diffusion between aquatic creatures' blood and the surrounding water. They have a large surface area to increase the area available for gas exchange and a lot of capillaries to increase the bloodflow through the gills.
I assume the question is referring to peppered moths in which case
The black species of peppered moths which previously stood out against the white tree bark will now blend in because of the layer of soot covering the trees, causing their numbers to rise. Furthermore the white moths which used to blend in will now be chosen against and their populations will fall.
Answer:
In eukaryotes, it is well known that polyadenylation is required to produce the mature messenger RNA (mRNA) molecule and it provides stability to the mRNA during translation initiation. In prokaryotic organisms, polyadenylation is required for the degradation of the mRNA in a mechanism that involves three steps: endonucleolytic cleavage, polyadenylation and exonucleolytic degradation. Moreover, it is also important to note that no evidence of polyadenylation has bee reported in some prokaryotes including the halophilic bacteria Haloferax volcanic (Slomovic et al. 2005).

The visual pathway is as follows
Retinotectal Pathway
1. Retina
2. Superior Colliculus
Retinogeniculostriate Pathway
1. Retina
2. Thalamus (LGN)
3. Primary Visual Cortex
The left Lateral Geniculate Nucleus receives info about the right visual field where the neurons in the LGN project their axon to primary visual cortex. In a person is unable to process right side of the visual field, there is issue in the left LGN of the visual pathway
