Answer: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.
Answer:
a
Explanation:
There are two major differences between mitosis and meiosis. First, meiosis involves not one, but Two cell divisions. Second, meiosis leads to the production of germ cells, which are cells that give rise to gametes. Germ cells are different from somatic cells in a critical way. Whereas somatic cells are diploid, meaning they have two copies of each chromosome, germ cells are haploid. The haploid nature of germ cells is vital to the process of sexual reproduction.
