Answer:
a. osteoblasts
b. osteoid
Explanation:
Osteoblasts are the fundamental cell of bone tissue. They are the cells that synthesize the bone matrix called osteoid from which it is made from the skeleton of bone fish, to the skeleton of humans. Since the bone skeleton is an evolutionary paraphiletic characteristic (it is present in several taxonomic groups that have evolved from the same ancestor).
Osteoblasts are responsible for the development and growth of bones during the juvenile stage of individuals and are also responsible for maintaining adult bone and regenerating bone when it breaks.
Osteogenesis is the process of differentiation of osteoblasts. The cells from which osteoblasts differ are called osteoprogenitors. The differentiation of osteoprogenitor cells, which come from the mesoderm, periosteum or bone marrow, is induced by growth factors called bone morphogenetic proteins (BMPs), capable of inducing the growth of bone, cartilage or connective tissue. When an osteoprogenitor cell receives a BMP signal, it quickly begins to express the genes to generate collagen, osteonectin and alkaline phosphatase, among other compounds necessary for bone growth. When the bone grows, it ends up wrapping some of the osteoblasts and they lose their ability to replicate, at that time they are dedicated to bone maintenance and not to their synthesis and are called osteocytes.
Cell division during mitosis is necessary for replacing damaged or dying cells, as well as repairing damaged or worn-out cells that occur naturally. The main mechanism behind growth is this kind of cell division.
<h3>
What are the consequences if mitosis stopped in the body?</h3>
Without mitosis, there wouldn't be any cell division or growth. The fact that genetic information cannot be passed on is most essential. All cell processes would be significantly impacted.
You might also suffer serious consequences, as your heart would have to beat by itself, among other things. Your bones or your brain wouldn't be immediately impacted, but your blood cells would.
Therefore, Every cell in your body would stop replicating itself if mitosis halted, which would induce a heart attack.
