<span>Farmer Brown might be hesitant to clone his corn because cloning eliminates the ability to sexually reproduce and provide genetic variability. There will be no variability in genes in these clones, because given that they are exact copies of their "parent," they will all be identical, without any difference or variation. This farmer doesn't want that to happen, which is why he is hesitant to take Farmer Green's advice.</span>

The rough uneven surface gets scattered;)
Answer: The lungs are well supplied with blood due to lots of capillaries covering the alveoli, constantly maintaining a large diffusion gradient, air is able to pass easily down this gradient due to the alveoli having very thin walls (one cell thick).
or
The alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this: they give the lungs a really big surface area. they have moist, thin walls (just one cell thick)
