That is the water vapor from our breath, that condenses to water droplets. Water vapor by itself is invisible - it becomes visible when it forms droplets.
The product of respiration that can be seen on really cold days would be the water vapour.
Photosynthesis is not really necessary for us to breath but necessary for us to live. This is because a by product of photosynthesis is oxygen and we need to have oxygen to stay alive
your guinea pig could have really bad breath either from a really bad disease or he could have been born with bad breath. my guinea has really bad breath too! Don't worry and stay calm! go to a vet and see what they say!
It depends. If you are really sportif your breath will be slower. If you don't really exersice your breath/heartbeat will be faster.
if you really want to know how your breath smells lick you hand then smell it.
Anything can smell your breath as long as it smells. P.S. This is a question that really has no purpose.
Brush your teeth and floss regularly. You can also use a tongue-scraper, it really helps. Mints/gum only covers up the smell....then it comes back worse! Mouthwash can kill the germs that cause bad breath. Look for mouthwash that does so specifically. You may also want to mention it to your dentist. If none of the above suggestions work, then there may be another reason for your bad breath. Talking to your dentist will help discover the cause of your bad breath.
no because if your really holding your breath you should be holding your nosie
Only if you hold your breath for a REALLY long time, like turning blue.
Try Grape Seed Extract Vitamins, they really work against this type of bad breath.
