Question

gina made a poster for plastic recycling week and included this information on her poster.
what corrections should gina make? check all that apply.
□ gina should put \cellulose\ under \synthetic.\
□ gina should put \plastic\ under
atural.\
□ gina should put
ubber tires\ under \synthetic.\
□ gina should put \starch\ under
atural.\
□ gina should put \dna\ under \synthetic.\
□ gina should put
ylon\ under
atural.\

Explanation:

• DNA: It is a naturally - occurring polymer found in living organisms. So, it should be under "Natural".
• Rubber tires: Natural rubber is a polymer, but rubber tires often use synthetic rubber (a synthetic polymer) due to enhanced properties. So, rubber tires should be under "Synthetic".
• Cellulose: It is a natural polymer found in the cell walls of plants. So, it should be under "Natural".
• Nylon: It is a synthetic polymer made through chemical processes. So, it should be under "Synthetic".
• Starch: It is a natural polymer (a polysaccharide) produced by plants. So, it should be under "Natural".
• Plastic: Most plastics are synthetic polymers made from petrochemicals. So, it should be under "Synthetic".

• Gina should put "rubber tires" under "Synthetic."
• Gina should put "cellulose" under "Natural."
• Gina should put "nylon" under "Synthetic."
• Gina should put "starch" under "Natural."
• Gina should put "plastic" under "Synthetic."
