Not the tailbone; probably not arm or leg bones- ribs are pretty important, so are the spine and the skull

I think there may be slightly more females in YA than males, about the same as in the world itself.  It depends on the category - seems to be more males in some categories, more females in others.

Male piercings are gay. I believe boy piercings may be regulated but not sure. In the boys case it would point to early onset gayness.

None. Males and females are essentially the same during development until a hormonal event causes males to develop male genitalia. Because of this, we have some of the same physical characteristics and thus males have nipples.

Hmmm.  If the pectoral girdle (that would be the rib cage) were as stable as the pelvic girdle, then breathing would hurt because the rib cage would not be able to expand.  Every time you breathed, you would throw up, which might entertain the third graders in an exploratory class (come to think of it).

No... you cannot make your bones smaller.\n\nAnyway, you want strong bones and dense bones. If you do less activity, your bones will be less dense and more activity, more dense. You'd want dense bones, which is healthy, b/c when you get older bone loss is a serious problem for women. So, when you're young, you need to build up bone mass.\n\nI wouldn't worry about your ribs. The boys are not looking at your ribs. :)

It's all speculation, but in general, larger animals have deeper voices. Male humans are about 20% bigger than females, on average.

that's not true not all girls are sexually active...and according to research boys are more active.

Usually boys / men because they have a larger lung capacity (on average)

Men typically have more muscle mass than females.  These muscles consume a lot of oxygen, which is carried by red blood cells.  More oxygen requirements = more red blood cells.

Either we have BBBGGG or GGGBBB. In both cases, there are 3! ways of arranging boys, and 3! ways of arranging girls. So 3!*3!*2 = 72.

Testosterone boosts growth in humans. Men have more testosterone which is why they are usually bigger. As men grow their larynx grows and the Adam's apple bulges.\n\nA larger larynx is also why men usually have deeper voices.
