Answer:
True
Explanation:
Meiosis is the kind of cell division that results in the production of daughter cells with each cell having half number of chromosomes as the parent cell. Meiosis is the cell division employed by reproductive cells to produce gametes/sex cells. Meiosis occurs in two stages i.e. Meiosis I and II. The chromosome number reduces by half in gametes in order to ensure that after fertilization of both male and female gamete, the resulting organism has the correct set of chromosomes. e.g diploid organism produces haploid gametes which fuses to produce a diploid organism again.
Mitosis is another type of cell division that results in identical daughter cells. They are identical in the sense that they possess the same number of chromosomes as the parent cell that divided. For example, a diploid cell undergoes mitosis to produce two diploid daughter cells.
Small bone fractures that develop in response to repetitive, cumulative trauma are known as stress fractures. These are fractures where bones are injured by overuse, they are commonly found in the spine, vertebrae, leg bones, feet, and the pelvis. They result from the accumulated trauma from repeated submaximal loading, such as running or jumping

Answer:
Endosteum plays an important role in bone repair, bone remodelling and appositional bone growth.
Explanation:
Endosteum consists of a soft and thin connective tissue that lines the cavity of femur and humerus. Some of the major functions of endosteum are as follows:
Bone remodelling: Endosteum can stimulate the bone resorption that leads to the formation of new bone from the outside.
Bone repair: Hematoma, at the time of bone injury causes the division of endosteal cells and helps in bone repair.
Appositional bone growth: Endosteum that line the osteoblast cell can secrete bone matrix and increases the bone diameter.
