(a)
Interpretation:
The shifting baselines has to be explained also the plastic items used for packaging have to be identified.
Concept Introduction:
Polymers are macromolecules which are formed a by number of repeating units called monomers.
(b)
Interpretation:
The plastic items that are contamination in water ways have to be identified.
Concept Introduction:
Polymers: Monomers combine together to form polymers. Monomers are the repeating units of small molecules which link together to form polymers and the process is called as polymerization.
Polymers are macromolecules which are formed a by number of repeating units called monomers.
