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.

Answer:
we'll use () to indicate the different boxes
( ) (r) (r)
(R) (Rr) (Rr)
(R) (Rr) (Rr)
You will have a 2 by 2 cell for your answer. One set of your test (rr) will go across the top as is shown and the other will be vertical (RR) as shown. Go down the line and put the letter you see at the top in each box and then do the same going across.
