Characterization and determination of the S/G ratio via Py-GC/MS of agricultural and industrial residues
Oksanka [162]

Characterization and determination of the S/G ratio via Py-GC/MS of agricultural and industrial residues.

<h3>What is the abstract?</h3>

To investigate the potential lignin values, agricultural residues (apple tree pruning, olive tree pruning, and almond shell) and industrial residues (kraft black liquor) were employed as source materials for lignin extraction via various fractionation procedures (kraft, organosolv, acetosolv and acetosolv and formosolv processes). Py-GC/MS, FTIR, and GPC were used to characterise the separated lignins. The fractionation method had a significant impact on the average molecular weight (Mw) assessed by GPC. The severe circumstances of the acetosolv and acetosolv-formosolv procedures favoured repolymerization, resulting in high Mw lignins. Because of the longer retention durations, the EKL had a smaller Mw. Except for almond shell lignin, which has the highest relative abundance of G-type phenols, all lignins have higher relative abundances of S-type phenols.

Answer:

Part A: The process of sexual reproduction is important because by this process organisms with varied genetic characteristics can be formed. Crossing over and independent assortment allow individuals to be born which are not alike to another and their parents. As a result, genetic diversity is produced.

Part B:

The process 1 is meiosis. The process 3 is development by mitosis.

The reproductive organs form sperm and egg by the process of meiosis. During this process, the number of chromosomes is reduced so that the number of chromosomes of an individual can be maintained.

The zygote converts into an embryo in a process called germinal development. The zygote replicates by mitosis to form into an embryo.
