Classify each material as a polymer or a composite. plywood ,plastic, concrete ,fiber glass ,paper ,nylon

A polymer is a single chained molecule that is  made up of repeating subunits called monomers. In contrast, a composite is a material that is made from combining two or more molecules with similar physical or chemical properties to produce a hybrid molecule.

Plywood- it is a composite made from sticking together thin strips of wood with glue to ake stable sheets.

Plastic- a polymer made of repeating units called monomers of some kind of organic compounds.

concrete- is a composite made from mixing water cement and rocks. The mixture is not repeating and can branch in different ways which discounts it from being a polymer.

fiberglass- is a composite made that has no repeating units but made from plastic and glass fiber.

paper- is a polymer made of a repeating units of a specific monomer.

nylon- is a polymer manufactured by reacting repeating units of monomers.

Explanation:

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
