Hello there!
Let's take for example plastic, plastic would take a good while for it to decompose. It wouldn't make sense for it to be "food produce" because food does decompose very quickly. Wood could be the answer, but wood wouldn't take that long for it to decompose, all it could use is some constant water and rain, and then the wood would then give old and just decompose. But even thought that is the case, wood cuttings would be the answer.
Vegetable peels would not take a long time.Most likely, they are probably to fastest in this list above. So, based from your options, your correct answer would be (wood cuttings).
(option a) would be your answer.
I hope you found this helpful
Explanation:
Two important ways by which humans have affected the carbon cycle, especially in recent history, are: 1) the release of carbon dioxide into the atmosphere during the burning of fossil fuels, and 2) the clearing of trees and other plants (deforestation) that absorb carbon dioxide from the atmosphere
A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis
• high solubility for the solute and low solubility for the carrier liquid.
• density difference vs. the carrier liquid greater than 150 kg/m. ...
• mid-level interfacial tension (5–30 dyne/cm)
• high resistance to thermal degradation.
