Answer:
Calcium salts give bone its a. tensile strength. b. torsional strength. c. flexibility. d. compressional strength.
The answer is Option D (Compressional strength)
Explanation:
Calcium is the most abundant mineral in the body, most of the calcium in the body are found in the bones and teeth. Calcium helps the body with not only building strong bones and teeth, but also assisting the body in sending and receiving nerve signals. If blood calcium gets too high or too low, the muscles and nerves will not function.
Bone which serves as a storage area for calcium are mostly made of the protein collagen, forms the skeletal framework of all vertebrates, and it plays a major role in calcium balance in the blood. Bone exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts. Functions of bone includes structural support of the body, protection of internal organs, attachment of the muscles, production of blood cells.
Calcium salts form crystals that give bones great strength. Bone mineral is formed from carbonated hydroxyapatite. Calcium hydroxyapatite is a naturally occurring mineral form of calcium apatite, it contains magnesium and carbonate and it is identical to the substance in teeth and bones. The collagen fibers give bone its tensile strength, and hydroxyapatite give bone its compressive strength.
Answer:
The solutions are classified according to their ability to scatter light rays.
We can't just use this property because some true solutions also contain undissolved solute.
Explanation:
Tyndall effect refers to the ability of a solution to scatter light rays. True solutions do not scatter light rays while false solutions scatter light rays.
Colloid particles are not large enough to be seen with naked eyes unlike suspensions. We should not confuse a colloid with a suspension because in a suspension, the dispersed solutes are seen with naked eye.
