b. the matrix of the bone contains osteoclasts and chondroblasts
c. narrow channels pass through the matrix to allow for muscle attachment.
d. the matrix of bone is mostly collagen with very little calcium.
e. all of the above are characteristics salts

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 organic matrix is about 20 percent of the net weight of the bone and is composed mainly of collagen , hence collage is the main structural component of the bone matrix .
