Answer:
The correct answer is option a. "oxygen".
Explanation:
Fermentation is the biological process behind the creation of beer. Saccharomyces cerevisia, the yeast used for beer's production can perform both aerobic cellular respiration and fermentation. In the presence of oxygen, Saccharomyces cerevisia would undergo aerobic cellular respiration and will broke glucose to carbon dioxide and will produce energy. In the absence of oxygen, the yeast would undergo fermentation and the glucose will be converted into ethanol (alcohol). If after the brewing procedure the alcohol content is almost zero, it is possible that oxygen is present in the fermentation reaction apparatus. Under the presence of oxygen Saccharomyces cerevisia will undergo aerobic cellular respiration not fermentation.

Answer:
If the decolorization is left on too long in the gram staining procedure,gram positive organisms will be stained Purple color and gram negative organisms will be stained with no purple color.
Explanation:
Gram staining is used to identify bacterial species which are either gram positive or gram negative.
The cell wall of gram positive bacteria contain thick layer of peptidoglycans which hold the stain crystal violet and thus it becomes purple color where as the cell wall of gram negative bacteria contain thinner layer of peptidoglycans which allows the washing of crystal violet stain and thus the cell wall is not stained with purple color.
