elixir [45]

Answer:

(Bone deposition),

(Bone resorption),

Remodeling

Periosteal ,

Nedosteal,

The compact bone,

Spongy bone.

Explanation:

The constant, dynamic process of continual addition of new bone tissue (bone deposition) and removal of old bone tissue (bone resorption) is a process called bone remodeling. This ongoing process occurs at both the periosteal (outer) and nedosteal (inner) surfaces of a bone.

It is estimated that about nedosteal of the adult human skeleton is replaced yearly. This process does not occur at the same rate everywhere in the skeleton. For example, the compact bone in our skeleton is replaced at a slower rate than the spongy bone.

Which of the following is not a negative consequence of upward urban growth? a. pollution b. creation of a “heat island” c. incr

Murrr4er [49]

Solution: C. Increased use of surrounding land

Upward urban growth will increase pollution as the number of people will increase. The increase in population and obstruction of free movement of air because of upward urban growth will result in a "heat island". Since the number of inhabitants is going to increase with upward urban growth, waste management will also become an issue.
