Roughly ages 10-19 but could even be considered 21
Assuming that this question is referring to fermentation using yeast to convert sugars to alcohol and carbon dioxide. The reaction will stop after a certain percentage of alcohol is produced. This percentage is usually 10-13 percent. The yeast cannot survive in this environment and will die. So alcohol and carbon dioxide production will cease.
DNA is a transforming actor
The correct option is D. There are four different nitrogenous bases in DNA molecules; these bases are joined together by different forces including hydrogen bonds. In DNA molecules, there are two hydrogen bonds between adenine and thymine while there are three hydrogen bonds between cytosine and guanine. Thus, the hydrogen bonds between cytosine and guanine is the stronger.
