E) All of the choices are correct. 18) The Golgi apparatus stores, modifies, and packages proteins and other products of metabolism. A) True B) False. 19) When a cell is deprived of oxygen, its lysosomes tend to burst and release their contents into the cell.
The preferred crystal is sodium chloride. Any other compound which is insoluble in the silicone, soluble in a solvent that does not dissolve the silicone, and which as a residue is harmless to the body, could be used instead. Water is the preferred solvent. Any other solvent which dissolves the crystals and not the silicone, and which leaves no deleterious residue, could be used instead. The properties of this foam will be improved, for the reasons stated above, by using a plurality of crystal sizes.
Polydimethylsiloxane (PDMS) belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones. PDMS is the most widely used silicon-based organic polymer, and is particularly known for its unusual rheological (or flow) properties. PDMS is optically clear, and, in general, inert, non-toxic, and non-flammable. It is also called dimethicone and is one of several types of silicone oil (polymerized siloxane).
