It depends on the DNA that is compared to another species to decide if the species are related or not. Like the human and the rhesus monkey they are very related because all of the genetic codes have the same DNA except for one.
External respiration takes place in the lungs, where oxygen enters the blood and carbon dioxide enters the alveolar air. Internal respiration takes place in metabolizing tissues, where oxygen diffuses from the blood and carbon dioxide diffuses from the cells.
<h3>What is respiration?</h3>
Respiration is recognized as the movement of oxygen from the outside environment to the cells within tissues, as well as the removal of carbon dioxide in the opposite direction.
External respiration takes place in the lungs, where oxygen enters the blood and carbon dioxide enters the alveolar air.
Internal respiration takes place in metabolizing tissues, where oxygen diffuses from the blood and carbon dioxide diffuses from the cells.
Thus, in this way, external respiration and internal respiration are co-dependent.

D) individual birds with the mutation are more likely to survive & reproduce than birds without the mutations.
This is because the mutation is increasing their ability to catch and eat insects, thus increasing their chances of survival. Due to natural selection, birds with this mutation are favored because of their environment and they will most likely survive.
Held together by hydrogen bonds between pairs of bases.
