explain why air-breathing could evolve in water-breathers, but water breathing would not re-evolve in air breathers?

QUESTION 6 Mammalian lungs are very different in structure compared to amphibian lungs. The lungs of mammals have highly complex branching patterns of airways. The lungs of amphibians are simpler and more sac-like. Over all, the lungs of mammals are capable of much greater rates of gas exchange compared to amphibians. Why is this? O The more complex structure provides more surface area across which gas exchange can occur. O A complex structure means that gases have more contact time with gases compared to a simpler structure. O Mammalian lungs are usually much bigger relative to their bodies compared to amphibian lungs. O The respiratory membranes of mammals are able to diffuse gases across them much faster than amphibians. QUESTION 7 Click Save and Submit to sve and submit.
