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.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
