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.
Silicone sealant does not dry. The process here is a polymerization of the silicone with moisture in the air to form a new semi flexible compound. At 45 degrees, the air is devoid of most moisture, so it will take a much longer time for polymerization to take place.bviously this depends on the thickness of sealant ! If the layer is only 4 or 5 mm. it will 'dry in about 20- 30 Min's. but not fully 'cure' for about 72 hours.
