We need to breathe oxygen to live.He kept telling me to breathe easy. I'd like to see him breathing easy while giving birth.The oxygen tanks allow us to breathe underwater for a while.
If you recall from basis chemistry, water is made up of 2 hydrogens and 1 oxygen. The reason why we can't breathe underwater is because the oxygen molecule is already bound to the hydrogen molecules. Oxygen in this form is useless to our lungs. Our lungs can't extract oxygen from water
Only if they're still attached to the mother's umbilical cord. And they don't actually use their lungs to "breathe". They simply receive oxygen from the mother through the umbilical cord.
"Breathe in and breathe out, for you must breathe to live."
Normally this would have to do with the origin and location of the plant. Long, thin leaves offer less resistance to water flow; these types of plants are normally found in fast, running water. Note: Not all underwater plants have narrow, thin leaves!
no but they can hold their breathe for long periods of time
you can't breathe underwater
Hippos can't "breath" underwater but they can hold their breath for long periods of time.
No, they have to surface to breathe. They can go a long time between breaths though.
Crocs as well as alligators CAN'T breathe underwater. When they dive, they hold their breath.
No, the arctic fox cannot breathe underwater.
They have gills. They do not breathe the same air that we do.
Without proper equipment no human can breathe underwater anywhere.
I will assume you are not joking. A fish does not hold it's breath it can breathe underwater using its gills.
Not very long. A shark cannot breathe out of water, a goat cannot breathe underwater, and many species of shark will eat the goat.
Of course not. Humans are only able to breathe underwater for a few seconds.
They once brathed with gills but have adapted and can be underwater for long time while holding its breathe. So they have lungs
