Time Runni Attempte 1 Hour, 5M Birds having one-way flow of air as it moves through the lungs 24/7 Proct Fish gills having counter-current flow of water and oxygenated blood Calci Epithelial membranes always being very thin and kept moist Live Frogs using their entire body skin for gas exchange 7 Phú

Answer 1

The right answer to the question is last option. The right example of maximizing the surface area for diffusion is the frog using its skin for respiration. The oxygen diffuses directly from their moist skin into the blood vessel under their skin and since the skin's surface area is larger than the lungs, the diffusion is maximised. Epithelial membranes are thin and moist as to provide least resistance to diffusion. All the other options are incorrect as they don't relate to the maximising the surface area.

Please give a thumbs up if the answer helped you. Thank you! :)
