Water
Whales alter their bouyancy depending upon the amount of air that they have in their lungs.
Ice will not sink in water as it is lass dense than wateras its volume is more. boats, trash, oil, people (with the lungs full of air), anything that is less dense than the water.
Because you dont breath when you drink water
Yes. I put my goldfish in water strait out of the sink. We have a well so I dont know about city water, but I know that you can put well water strait out of the sink. Hope this helps.
explain why certain bugs can walk on water? is because they have webbed feet.
Absolutely. Everything that breathes air has lungs.
no they dont float like normal people
The lungs can't have water in them. Just to keep them moist. But if they did have, i dont know, 86 percent water, just for say, you would like so called "drown" on land I guess.
In fresh water a human is more dense than the water around him or her causing them to sink slowly. In salt lake the water is more dense than the human because of the fact that it has salt in it causing the human to float. Also have you ever noticed that if you fill your lungs with air the in fresh water you will float, but if you fully deflate your lungs you will sink? pretty cool huh?
Your lungs expanding and closing.
