Bones are hard and contain mineral salts.
It is because bone has functional and developmental commonality with the class of connective tissues.Like other connective tissues:Bone provides structure and support;.Bone is derived from embryonic mesoderm;Bone contains substantial amounts of non-living, non-cellular tissue.
The perioisteum is the connective tissue covering the bone.
Bone tissue is a connective tissue with a stony hard matrix due to the presence of mineral salts, primarily calcium and phosphate, that provide strength and rigidity to the structure. Bones are important for supporting the body, protecting organs, and serving as attachment points for muscles.
High mineral content (calcium salts).
To prepare hard water, simply dissolve calcium and magnesium salts like calcium chloride or magnesium sulfate in regular water. The concentration of these salts determines the hardness of the water. The dissolved salts will increase the mineral content of the water, making it hard.
Osseous tissie
Bone is a composite material, like fiberglass (something hard [and thus brittle] in a matrix of a more flexible substance. In fiberglass the glass makes the (fishing rod) strong, the plastic makes it tough. In bone, the calcium salts make it strong and hard, the connective tissue makes it tough.
Mineral salts from calcium and phosphorus compounds are essential for making bones hard and strong. calcium is the most essential mineral to make bones strong but not all bones are as hard as you think some bones are "Spongy" but we just dont notice it. hope this helps if you need to know this....
Osseous tissue is the hardest tissue of the skullcap. The cells are arranged in concentric circles around the nutrient canal and the matrix is hard due to the calcium salts.
The type of connective tissue matrix that is hard due to calcium salts and forms the hip bone is known as bone tissue, specifically osseous tissue. This matrix is mineralized, primarily composed of hydroxyapatite crystals, which provide strength and rigidity. Bone tissue also contains collagen fibers that contribute to its structural integrity and flexibility. Overall, this unique composition allows bones to support the body and protect vital organs.
Calcium is a relatively hard mineral with a Mohs hardness of 3. It is commonly found in bones and teeth, providing strength and structure to these tissues.
Some bath salts soften hard water.
