Answer:
The air pressure at Mt. Everest is much less than the air pressure at sea level because air pressure decreases with altitude. This is because at higher altitudes, there is less air pushing down from above. An addition, gravity is weaker, as it is farther from Earth's center. Because of this, air molecules can spread out more at higher altitudes, resulting in decreasing air density.

Answer:
Protein synthesis, increases, brittle, fracture, dimineralisation, ossification, 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 loses calcium and other minerals(dimeneralisation). The bones of the skeleton become thinner and weaker, resulting in insufficient ossification, a condition called osteopenia.
