The skeletal system stores minerals and maintains mineral:
c) homeostasis
The correct answer is c) homeostasis. Homeostasis refers to the body's ability to maintain stable internal conditions despite external changes. In the context of the skeletal system, it plays a crucial role in regulating mineral levels such as calcium and phosphorus. These minerals are essential for various bodily functions including muscle contraction, nerve signaling, and bone strength. By storing and releasing minerals as needed, the skeletal system helps maintain the mineral balance in the body, which is vital for overall health and functioning.
