The fact that they can breed but cannot produce fertile offspring shows that they are different species. T<span>hey may have different characteristics which means they cannot breed </span>successfully, too.
I hope this helps! :-)

Answer:
D. partial pressure of oxygen
Explanation:
Partial pressure refers to the force applied by an individual gas per unit area in a mixture of gases which is measured in mm of Hg. The partial pressure determines the movement of the gas molecule in the system.
In the given scenario, the oxygen transport through the blood along with other gases like carbon dioxide and other minute concentration but the gaseous exchange between the lungs and the blood, between the blood and the tissues depends on the partial pressure of the oxygen. The oxygen moves from the higher pressure to lower pressure therefore partial pressure is the determining factor.
Thus, Option-D is correct.
The correct answer is (D) Penguins and ducks develop in a more similar way since their common ancestor is more recent than the common ancestor of penguins and bats or ducks and bats.
The birds such as penguins and ducks develops in a similar way since their common ancestors are more recent as compared to the common ancestors in case of penguins and bats or in case of ducks and bats. The birds and bats do not share any recent common ancestors according to the phylogenetic tree.
