Answer:
Declining crude birth rates.
Explanation:
Birth rate may be defined as the number of births takes place per year per thousand of the population. The birth rate and death rate may change the population dynamics.
The developing countries shows the expanding population graph as they have more number of people of the reproductive age. The advancement in the medical field results in the decline birth rate that causes the decline of the nature resources.

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>
