The order for the necessary enzymes that act to repair a thymine dimer by nucleotide excision repair is Endonuclease, DNA polymerase I, DNA ligase. Thymine dimer repair may be done by two mechanisms; Photoreactivation repair, the pre enzyme activated by blue light breaks the dimer restoring the normal base pairing. The other method is excision repair; where the uvr system excises the dimer, and the gap is filled in by the proof-reading activity of DNA polymerase I.

Explanation:
Whales use their lower jawbone to the middle ear. whereby they can ear clearly while they are in the water. Human ears and dolphins ears they work the same . They receive sound directly from the air.
In similar way dolphins and human ears are placed in basic anatomical location which is same as on the head. Without a medium hearing is not possible.
The medium sound for human is air. Sound travels 343 meters per second in air and 147 meters per second in water. The most effective way of transmitting sound waves is through water.
We can say that the sound will be fast to travel in medium if the molecules are closer.
