Answer:

b. they require more oxygen per unit of volume.

Explanation:

Large animals have a specialized organs for exhalation and inhalation of gases due to the requirement of large amount of oxygen for cellular respiration.

UkoKoshka [18]
The answer is <span>analogues structures evolved from two different ancestors.</span> 


A convergent evolution is a phenomenon of independent evolution of similar traits in species that are in different lineages. These traits are called analogues structures. They are similar in form or function but were not present in the last common ancestor of those species. So, the appendages of cockroaches and turtles are analogues structures with the similar function - creeping movements, and they are the result of the convergent evolution, but they evolved from two different ancestors.
