Question

polymer
many __________ (subunits or
building blocks) that __________

sketch an example of a polymer in the space above

Explanation:

A polymer is made of many monomers (subunits or building blocks) that are linked together (through processes like polymerization). For example, a protein is a polymer made of amino acid monomers linked by peptide bonds, or a nucleic acid like DNA is a polymer of nucleotide monomers linked by phosphodiester bonds, or a polysaccharide like starch is a polymer of glucose monomers linked by glycosidic bonds.

Answer:

First blank: monomers; Second blank: are linked together (or "join together", "polymerize", etc. depending on context); Example sketch (description): For a polysaccharide like starch, you could draw a chain of hexagon - shaped glucose molecules (monomers) connected by lines (representing glycosidic bonds) to show the polymer structure. For a protein, draw a chain of different - shaped amino acid monomers (with the typical amino acid structure of an amino group, carboxyl group, and R - group) connected by peptide bonds. For DNA, draw a double - helix - like structure with nucleotide monomers (each with a phosphate group, deoxyribose sugar, and a nitrogenous base) connected in a chain and the two chains hydrogen - bonded together.
