~~16. while watching a special on animals, brianna discovers that hares tend to lose heat through their ears. based on this and what is known about surface-to-volume ratios, propose an explanation as to why hares that live in hot climates (such as the desert) have large, extended ears

The hares live in the desert. They have an exposure of extremely hot temperatures and this is the reason that hares have special adaptation for surviving in hot temperatures. They have large ears with higher number of blood vessels.

When the temperature of the surrounding environment is slightly less than  the temperature of hare's body as when it moves from a hot place to a shady place, the blood vessels on the outer part of the ear widen which is called as vasodilation.

This results in loss of heat from the body through ears due to cooling surrounding.

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
