What are the functions (jobs) of the skeletal system?

The function of the skeletal system is to protect our vital organs, to give our bodies a shape, it works with the muscles to allow us to move, and it stores nutrients like calcium that makes bones hard.  

hope this helped.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

it is a limiting nutrient limited by a single nutrient in the ecosystem, & the single goes very slow.
