Answer :True
Phenol red fermentation tube is very
simple basic medium with Phenol red indicator.
It has no source of sugar or Carbon except for the sugar added to
the medium.
Hence, it is made with sugar of choice for which we need to see the
fermentation. Thus, each organism can be checked for fermentation
of different sugars.

Activity 3: Yeast Fermentation of Different Carbohydrates? Experiments test the predictions made by a hypothesis. The hypothesis should be stated very clearly and unambiguously. If the results of the experiment were predicted by the hypothesis, the results support the hypothesis (NOT “prove the hypothesis is true"). If the results are different than those predicted by the hypothesis, then the hypothesis is retested, modified or discarded. Many times an experiment is actually testing the Null Hypothesis. The null hypothesis states that...
