<span>All things that are found within the Earth are one way or another, composed of carbon. Carbon is very abundant within metals that are dug from the Earth and they can also be seen making up parts of the human body’s bones to make it light weight. Most scientists believe that throughout the evolution of Earth, carbon has always been present and makes up most of the materials that have existed before. </span>

Explanation:
In general, tumors occur when cells divide and grow excessively in the body. Normally, the body controls cell growth and division. New cells are created to replace older ones or to perform new functions.
Answer:
(<u>Bone deposition</u>),
<u>(Bone resorption</u><u>)</u>,
<u>Remodeling</u>
<u>Periosteal</u><u> </u>,
<u>Nedosteal,</u>
<u>The compact bone, </u>
<u> Spongy bone.</u>
Explanation:
The constant, dynamic process of continual addition of new bone tissue (<u>bone deposition</u>) and removal of old bone tissue (<u>bone resorption</u>) is a process called bone <u>remodeling</u>. This ongoing process occurs at both the <u>periosteal</u> (outer) and<u> nedosteal </u>(inner) surfaces of a bone.
It is estimated that about <u>nedosteal</u> of the adult human skeleton is replaced yearly. This process does not occur at the same rate everywhere in the skeleton. For example,<u> the compact bone</u> in our skeleton is replaced at a slower rate than the <u>spongy bone.</u>
