15. In another experiment, a scientist puts yeast with both glucose and galactose as a nutrient source. Predict how the yeast would use the nutrients, and justify your prediction with evidence from the experiment completed in

this activity.

Fermentation occurs in glucose whereas no fermentation occurs in galactose.

Explanation:

Yeast will use the nutrients such as glucose and galactose from the process of respiration. Yeast will break down the nutrients with the help of oxygen produces high amount of energy. This energy is used by the Yeast for their growth. In the presence of yeast glucose quickly undergoes fermentation while no fermentation occurs in the medium having galactose.

the index of refraction of the second medium is higher. i just took the test trust me !
