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.
This is strong evidence for the hypothesis that the chroloplast originated ais a symbiotic cyanobacteriam that became permanentely incorporated into its host.the complete genome sequence of cyanobacteria and of the higher plant arabidopsis thaliana leave no doubt tha chroloplast originated through endosymbiosis from a cyanobacteriam
The Structural Organization of
Cells. The cell is the smallest matter that still absorbs the characteristics
of life. All cells have three basic parts, a plasma membrane splits each cell
from the environment, permits the flow of molecules across the membrane, and
consist receptors that can affect the cell’s activities. A DNA-containing
region occupies a portion of the interior. The cytoplasm contains
membrane-bound compartments (except bacteria), particles, and filaments & end
ash; all bathed in a semifluid substance. Eukaryotic cells are defined by their
possession of a membrane-bound nucleus. Prokaryotic cells have no defined
nucleus; the only representatives are bacteria.
