Question

what is the chemical term for the long molecules made of smaller repeating units that make up the fibers in textiles?
select one:
○ cellulose
○ palindromes
○ silk
○ polymers
○ proteins

Explanation:

To solve this, we analyze each option:

• Cellulose: A specific polysaccharide (a type of polymer), not a general term for long molecules with repeating units in textiles.
• Palindromes: Related to sequences (like DNA or words) that read the same forwards/backwards, not a chemical term for textile - related long molecules.
• Silk: A natural fiber, not a term for the long molecules made of repeating units.
• Polymers: By definition, are large molecules made up of many repeating structural units (monomers). Textile fibers (both natural like silk, cotton and synthetic) are made of polymers. For example, silk is a protein polymer, cotton is a cellulose polymer, and synthetic fibers like polyester are also polymers.
• Proteins: A type of polymer, but the question is asking for a general term for long molecules with repeating units in textiles. Polymers is a more general term that encompasses proteins (in silk, wool), cellulose (in cotton), and synthetic polymers (like nylon, polyester).

Answer:

Polymers (the option with the label "Polymers")
