As our all basic needs is fulfilled by aerobic respiration but when it comes to vigorous exercise when there is a shortage of oxygen , muscles starts using anaerobic respiration to full fill the need !
another example of anaerobic respiration in our body is in RBC ! Here there is no mitochondria so it has to do anaerobic respiration !
Answer:
- <u>Conventional plastics-</u>
"Plastics are typically organic polymers of high molecular mass, but they often contain other substances."
"Oil-based polymers is currently used in packaging applications. These are virtually all non-biodegradable, and some are difficult to recycle or reuse due to being complex composites having varying levels of contamination.
- <u>Biodegradable plastics</u>-
"They are largely manufactured from renewable natural resources, to produce biodegradable materials with similar functionality to that of oil-based polymers."
Explanation:
<u>Complex Issue-</u>
- Diversity of biodegradable materials and their varying properties makes it difficult to make simple, generic assessments such as biodegradable products are all ‘good’ or petrochemical-based products are all ‘bad’.
- Biodegradable packaging materials are most suitable for single-use disposable applications where the post-consumer waste can be locally composted.
