1. How do salts keep wet roads from freezing?

2. How does an animal’s appearance change as it grows older?

Salt raises the freezing/melting point of water.

Second question please!

Doesn't it depend on the animal, or at least the *kind* of animal? I mean, changes in mammals are completely different from changes in birds, of fish, say.

As humans age, their faces get wrinkled, and their hair thins or turn gray. How does an animal’s appearance change as it grows older?

Does that help?

Isn't it the same?

Rath, I do not know the answer. The Student Board was no help!

Well, in general, since non-human animals have shorter lifespans than humans do, their growwth pattern is very different. Many animals -- say, a dog -- will reach their full-size by the time they're a year old or so. It's even less for some animals, but for the length to be as long as 18 years is very exclusively human. Because of this, the transition from baby to adult is often far more drastic -- a bird will have a very defined stage of losing its baby feathers; a cat will lose its baby fur. A lot of times, there's color change involved, too.

Animals age, too -- again, say, a dog. As dogs get older, their hair turns grey, usually in the area directly surrounding the face. Signs of aging definitely aren't so prevalent in all animals, but that's the best example I could think of.

It's sort of hard to give an over-arching explanation, but the question seems like it's just asking for examples of ways in which changes occur, so hopefully that helps you.
