1 Printing Inks are NOT opaque! They are slightly translucent, which means the color of the paper effects the color. So PANTONE Blue 072 looks one way on white paper, but on natural, off-white, or colored papers it would pick up some of the color of the paper.  Transparent White is NOT white ink....
Anaerobic respiration occurs in the absence of oxygen, unlike aerobic respiration. Some organisms such as certain types of bacteria carry out anaerobic respiration as the main or only kind of respiration, while other organisms such as ourselves only carry out anaerobic respiration under special circumstances.
Individual human cells are also facultative anaerobes: They switch to lactic acid fermentation if oxygen is not available. Summary: 1. Aerobic bacteria inhales oxygen to remain alive. 2. Anaerobic bacteria dies in the presence of oxygen, and therefore avoids O2. 3. Aerobic respiration produces energy with the help of a complex process in the cells. 4. Anaerobic respiration produces crystals, and causes pain in muscled areas. 5.
