The zebra story about the bird poop and the charcol was great! I have to remember that to tell to the step-kids. But I do have to say, that animals have a basic color of skin as m^e said, and there are different variations of zebra, so it would all depend. The others, well, I have no clue but it's cool to here the theories. And it's true you learn something new everyday. I never knew hockey rinks were painted and taped. Great topic!

Can you tell by looking at the colour of their nose? Do the black-skined ones have black noses and the white-skinned ones white noses? Or maybe their hooves are different, too?

Why is that the earth, sun and all the solar bodies are of the shape if a circular object? is it because of the velocity and the path of its moment. can you answer soon enough

Sorry, your physics failed you. Increasing pressure increases the boiling point. That is why pressure cookers cook faster. The water doesn't boil until a higher temperature is reached. It is the same reason why you shouldn't take off the radiator cap on a hot engine. You release the pressure, and that returns the boiling point to normal, and the superheated water boils over. What you need to do is lower the pressure to lower the boiling point.
