What is the advantage of breathing through the nose rather than the mouth?

The advantage of breathing through the nose rather than the mouth is that when using the nose, this can create a back flow of the air we exhale in the lungs rather than the mouth. And in the same time, the nose filters the dirt that we may inhale than the mouth in which it does not.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
