Answer:
a. The bone matrix is very dense and contains deposits of calcium salts
Explanation:
Characteristic of bone tissue
The mineralized matrix of the bone tissue has the organic component which is mainly collagen known as the ossein and an inorganic component of mineral composed of various salts .
The tissues of the bone contain an organic primarily hydroxypatite , calcium carbonate and collagen .

The answer is b. wave because that’s other ones aren’t related to that in that way.
Answer:
option d. Hypertrophy and neural facilitation.
Explanation:
Strengthening of muscles or say the capacity to generate force of muscles can be improved by training the muscles with the help of neural facilitation and hypertrophy.
Neural facilitation is the process that transfers the stimuli to the muscles
To overcome the deficiency of oxygen during training of muscles, the muscles grow in size. this phenomena is termed as Hypertrophy.
