When the bone food into the bone

you nose and erase are supported

Your body breaks down food into protein in which the protein will then help to heal any problems your body has, like a broken bone. Protein can also help your bones to gain more strength, if your bones are stronger they are less likely to break. 

For the second question, I think you're asking what are your nose and ears supported by, and if you are I think the answer would then be "cartilage."

I hope these answers helped you. :)
