Answer 1

b. evaporating d. the short legs

Answer 2

For the 2nd question I think the answer is d

a dog having short legs confers no advantage (that I can think of )so it wouldnt undergo natural selection.

People might want dogs with short legs cause theyre cuter? Just like how you might breed dogs for a certain coat color

and 1st questioni think its evaporation : more sun=more evaporation?
