Which phrase describes a polymer? a. a branching structure containing 10 carbon atoms and 22 hydrogen atoms b. a crystal containing many sodium ions and many fluoride ions c. a long chain of carbon atoms with hydrogen atoms attached to them d. a molecule containing six carbon atoms arranged in a ring structure e. a single atom of calcium bonded to two atoms of chlorine

Answer is: C. a long chain of carbon atoms with hydrogen atoms attached to them.

Starch is example of polymer.

Main component of bread is flour and main component of flour is starch.

Starch is a polymeric carbohydrate consisting of a large number of glucose units bonded by glycosidic bond. Starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.

Another example, polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomer styrene.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
