Question

(show all your works and measure that you answer all questions from part a to part c. thanks you)

use a picture below to answer all questions below:

a. Introduce the hypothesis that is being tested in exercise 2 of the fermentation lab. Briefly explain how you will be testing your hypothesis.

b. Provide a graph of your results from Table 2. Be sure to label the axes, provide an appropriate title, legend, and figure number.

c. Describe your results (but leave the analysis/interpretation for the next section): Are the rates steady (e.g. is the slope the same over the time period, or does it increase quickly, then decrease, etc.)? Which substrates had the highest and lowest amounts of fermentation?

3. Formulate your hypothesis. Remember, the hypothesis must be testable 4. Write your prediction indicating what you expect to observe as the result of this experiment (if/then) 5. Design your experiment and enter the number of tubes you need for a properly contr eriment and enter the number of tubes you need for a properly controlled in the following table.

Answer 1

3). Alcohol can be produced by the fermentation of sucrose by the baker's yeast. Initially, the organism reproduces by aerobic respiration, if all the available oxygen is utilized, then the organism starts fermentation.

If respiration occurs, CO2 gas is produced. If the respiration is aerobic, the amount of gas produced is less and if the respiration if anaerobic, the amount of gas produced is anaerobic.

Hypothesis: The test tubes inoculated with the higher concentration of yeast ferments alcohol at a faster rate, so more carbon dioxide is produced.
