Explain why chemists
refer to the joining of monosaccharides molecules to form disaccharides as a "dehydration
synthesis" reaction. (aka: condensation reaction).

It is referred to as a hydration/condensation reaction because this reaction involves the production of a water molecule as a by-product of the formation of the glycosidic bond. When two monosaccharides join, the 4’ C of one monomer forms a covalent bond the 1’ C of the other. One Carbon loses an –OH while the other a –H during the formation of this bond. An H+ and an OH- then combine to form a water molecule.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus. this is so because calcium carbonate is the main component in the shells.

explanation:

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
