Match the function of bone on the left with a an example of that function in use on the right. A. Muscles exert force against bones B. The body's mass is suspended from bones and rest upon bones C. The lungs are surrounded by the ribs D. Calcium is released from bones to restore the calcium levels in body fluids

First let's add the missing piece of information

1. Protection

2. Electrolyte balance

3. Movement

4. Support

The answers

A. 3

B. 4

C. 1

D. 2

Explanation:

 A. Muscles exert force against bones -3. Movement

Muscles puts a force on bones during contraction to cause body movement and lifting of objects.

B. The body's mass is suspended from bones and rest upon bones -4. Support

This provides support.

C. The lungs are surrounded by the ribs -1. Protection

The lungs are protected by the rib cage (12 sets of ribs) connected to the spine and around the lungs for protection.

D. Calcium is released from bones to restore the calcium levels in body fluids -2. Electrolyte balance

The bones is rich in calcium. It is deposited at high blood levels and released at low blood levels as it is controlled by PTH, vitamin D, and calcitonin.

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