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.
The carbon dioxide produced as a by-product when yeast perform alcoholic fermentation on the sugar in the bread mix is the gas that causes dough to rise. The sugars in produce like barley, grapes and other grains and fruits is what allows yeast to produce the bubbles and alcohol in beer, wine and other liquors.ome organisms do not need as much energy as others and sometimes the conditions do not allow for aerobic respiration run successfully. In these situations it may be necessary for organisms to run a process known as anaerobic (literally meaning without oxygen) respiration.
