yes you can breath through both nostrils or at least i can .
it doesn't really matter, because both trap dirty and dust. the only difference is that you normally don't breath louder through your mouth.
Yes humans breathe through both nostrils BUT you don't to breathe through both. Its better to breathe through your nose then it is through the mouth because the hair gets rid of more particles in the arm and it warms and mosterizes the air so the air gets to the lungs better!!OMG hehehe i am writing an answer and someones gonna read it so all i have to say it like hi I'm in grade seven i am alwas overly hyper and CHOWWW!
Both, breathing through your nostrils act as a vent-like mechanism filtering out pollution from the air, and breathing through your mouth fulfills your lungs with the right amount of oxygen it needs.
To answer both of your possible questions: No. Tights are not supposed to be see through.
Atlantic puffins breathe through their nostrils, located at the base of their beaks. They have a unique adaptation where they can close their nostrils to prevent water from entering while they dive underwater to catch fish. This allows them to efficiently navigate both in the air and underwater.
With their lungs rather than through their lungs, but yes - both dolphins and kangaroos breathe with lungs.
Sure you can
No. It is more instinctive for to breath through our noses because where far more air can get from the harmful substances in the air that us. Plus it takes less effort than breathing through your mouth
Well first you do a few stretches before you run. Just do some leg twists. Then you start off as jogging and each two steps you take, you inhale then exhale. Do it how ever you feel is more comfortable to you. Then just keep up the pattern.
Yes, in a way. You may not know it, but when you breath through your mouth, you breath through your nose a little bit too. And when you breath through your nose you breath through your mouth (if its open). Dogs can do the same, usually in the summer, they breath through their mouths to cool off, right? So they need to smell, a lot, so during the summer they usually do both (unless its air conditioned).
The simple answer is no, dolphins don't have gills.
