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.
In animal cells (like humans) anaerobic respiration happens mostly on muscle cells through a process called Fermentation that happens outside the Mitochondria. The end products of this process are ATP (less than in aerobic respiration) and Lactic acid.est Answer: Anaerobic respiration occurs in muscle cells when they do not have access to enough oxygen to complete aerobic respiration to generate all the ATP they need. In human muscle cells, the end product is lactate/lactic acid. Source(s):
