 What does it mean to be a good mathematician?

As students build their mathematical proficiency, they become more confident  to learn and use math. And anyone who has great skills is also a good mathematician even if they do other jobs.

science - Bones

Bones

What are bones.?   Bone is the substance that forms the skeleton of the body.  Muscles pull against bones to make the body move. Bone marrow, the soft, spongy tissue in the center of many  bones, makes and stores blood cells.

How does our body make them.? 

Bones kinda do have a similar life cycle as a living being. They start as cartilage that is like a plastic/rubber padding. As a young life form is being born by in a mammal or a mother’s womb. The skeletal system begins to form a framework of cartilage. Before birth, there is a certain amount of hardening of bones/limb bones to allow the human being to somewhat stand properly after a few months or so on. Even so, the greater part of a skeleton framework is cartilage at birth. After birth, the bones or cartilage in the skeleton begins to harden. The continues throughout life forms life until old age, a small amount of cartilage is left and bones are now old and brittle. Also, the process of hardening is called ossification. 

- Ossification/ Hardening is a process of adding new bone materials/cells called osteoblasts.

How do they grow/repair.?

Bones grow and are repaired by the process of getting elderly. Bones also repair themselves naturally. Here’s how bones heal:

1. Immediately after a fracture occurs, a blood clot and callus form around it.

2. New threads “threads” of bone cells start to grow on both sides of the fracture line toward another. 

3. Eventually, the fractures close up and the callus is absorbed by the new cells. This process may take from six weeks to a year.

Bones grow and get healthy with the help of Calcium, Iron, Vitamin D, Protein, and fluoride.
