The bones of the skeleton become and susceptable to . Second, bone (loses calcium and other minerals). The bones of the skeleton become thinner and weaker, resulting in insufficient , a condition called .

a. Protein synthesis

b. Increases

c. Brittle

d. Fracture

e. Demineralizes

f. Ossification

g. Osteopenia

Explanation:

Aging affects bone in two ways. First, the tensile strength of bone decreases due to a reduced rate of PROTEIN SYNTHESIS by osteoblasts. Consequently, the relative amount of inorganic minerals in the bone matrix INCREASES The bones of the skeleton become BRITTLE and susceptable to FRACTURE. Second, bone DEMINERALIZES (loses calcium and other minerals). The bones of the skeleton become thinner and weaker, resulting in insufficient OSSIFICATION , a condition called OSTEOPENIA

Aging occurs in people as they grow older due to a reduction in the density of their bones. The mineral content of the bones tend to decrease thereby making the bones brittle and more susceptible to fracture( breaking of the bones)

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
