Why does aerobic respiration produce more ATP than anaerobic respiration?
erik [133]
Aerobic respiration produces more ATP than anaerobic respiration because aerobic respiration occurs when oxygen is present and is then able to produce ATP as normal with a profit. However, anaerobic respiration has a lack of oxygen, which leads to either fertilization, only producing enough ATP to keep the cycle going and the cell surviving, (not creating any excess/profit ATP).

bixtya [17]

Answer: The NEGATIVE CONTROl is the test tube that is filled with ONLY distilled water.

Explanation:

A negative control of an experiment is carried out alongside the main primary experiment except that the treatment is changed to something that is predicted to have no result. In the negative control, the student does not expect any response. This would help the student compare the result of a new experiment against an already known existing results.

Analysing the experiment carried out by the student, She filled two test tubes with distilled water and placed a piece of Elodea in one of the tubes, leaving the other without a plant. The other test tube that contains only distilled water is the negative control because she wasn't expecting any result from it. It's also served as a control sample to the primary experiment. This is observed as she blew in each tube to add carbon dioxide, which caused the distilled water to become more acidic. This would help the student know that the that experimental results are valid and to ensure that time is saved.
