Answer:
Birds require high levels of oxygen and, therefore, high rates of gas exchange due to flight demands. Avian resting oxygen consumption is high compared to that of mammals and other vertebrates, and this increases even more during the flight.
Explanation:
Compared to mammals, birds have specific adaptations of the respiratory system that result in higher levels of oxygen exchange.

Explanation:
<h2>Mutation will occur </h2>
Explanation:
Base excision repair operates for small DNA damage such as deaminated bases
- DNA glycosylase plays an important role in cleavage of glycosidic bond of abnormal base (does not cleave phosphodiester bond)
- Uracil is incorrectly paired with guanine then mutation will occur
- The original GC base pair will change into AT base pair(transition of GC to AT)
- Transition is a mutation in which one purine(adenine or guanine) is substituted for other or one pyrimidine(cytosine or thymine or uracil) is substituted for other
