Want this question answered?
the slime layer
to provide a protective layer or coating for the sample if the sample is a reactive sample. forming a protective layer or coating would prevent decomposition of the sample during the IR reading process.
Lithosphere
Mononuclear cells
There could be many slogans for ozone layer. Ozone protection, Life protection is one of them.
Clevenger apparatus is used to determine the volatile oil content in a given sample. The oil layer settles on top of the aqueous layer.
i think mechanism is that,,thin layer chromatography is basically separation of mixture,and sample might adsorb on silics surface.here is adsorption mechanism
Sediment trapping and the growth and metabolic activities of matlike cyanobacteria colonies contribute to the creation of stromatolites. Small particles of calcium carbonate settle onto the sticky matlike colonies of cyanobacteria forming thin layers of calcium carbonate. The cyanobacteria then build up over the calcium carbonate layer (so as not to be buried and killed) producing another sticky surface where more fine particles of calcium carbonate can be trapped.

The upper layer that is floating on the surface of Zinc Furnace bath will be pulled out by a mechanism called drossing and the collected matter is Zinc Dross.
Methane gas is hard to collect and destroy in large quantities. The gas that isn't collected will most likely rise and damage the o-zone layer. (Methane is a main cause of global warming).
Salt is collected after the saline water evaporates to leave the raw salt dry. Water is collected in a large area for the thin crust of salt and requires a flat large pan to scrape the top thin salt layer.
