Bones are composed of a type of connective tissue called osseous tissue, immature bone cells that produce bony tissue are called osteoblast, large bone cells that digest bone tissue to shape the bone and smooth it out are called osteoclast, and mature bone cells are called osteocytes.

Explanation:bones are made up of 15% water,30% collagen fibres and 55 % mineral salts.

The collagen makes the bone soft and flexible.the mineral salt makes the bone fragile and strong.

The osseous tissue contains the osteogenic cells which are stem cells.they are differentiated into osteoblasts.osteoblasts build bones and are important in the external matrix of the bone.osteoclast forms osteocytes,which are the main bone cells.

Osteoclast breaks down older tissues in order to keep the bone strong.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

the titanic would be the correct answer
