Why are calcium, magnesium, phosphorus, and fluorine important to human health?
a. lipids that support bones
b. minerals that support bones
c. vitamins that support bones
d. proteins that support bones

I believe the answer you're looking for is B.) Calcium, Magnesium, Phosphorus, and Fluorine are all essential nutrients for the body and they are all Elements on the Periodic Table.

Hope this helps!

Yeah, the answer is definitely b.assuming that you're a high school student or middle school student, you probably don't need your parents' to pick out your clothes anymore. and i don't know how it works at other schools, but i know that at my high school, you don't get to pick the book you read for an english assignment. your teacher picks that. the decision of what after-school job i should get, i would definitely make with from my parents and other people that i trust. ultimately, the decision is up to me, but i would need advice from people who are more experienced.

The answer would be age 18.
