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: It would be approximately 22% thymine.
I believe it is A!
the punnet square would be:
B B
b Bb Bb
b Bb Bb
and since capital letters represent dominance and black is dominant, it would be 4 black guinea pigs!
