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.
Sublimation is the phase transition of a substance directly from the solid to the gaseous phase without passing through the liquid phase.
Here are the three forces that exist between two NH3 molecules:
1- Dispersion forces - these forces exist between ANY two molecules, regardless of anything else.
2- Dipole-dipole interactions - NH3 is a polar molecule with a permanent separation of charge. Each molecule behaves like a tiny magnet and has + and - poles so 2 NH3 molecules attract each other. Dipole-dipole interactions are stronger than dispersion forces in small molecules.
3- Hydrogen bonding - H is directly bonded to the extremely electro negative atoms N, O, or F, hence hydrogen atom is nearly stripped off electrons due to the large electro - negativity difference. Hydrogen being a small atom further reduces in size even allowing it to approach other molecules very closely. Here N,O,F gathers more partial negative charge.
Due to the close approach between the molecules and the strong partial charges, hydrogen bonding is generally more important than dipole-dipole interactions.
So the main intermolecular force must be hydrogen bonding.
Answer:
Explanation:
Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Im pretty sure the answer is distance and mass
