Our hypothesis is based on the performance of students in the tests given the amount of time they studied last night before the exam. The testable version of the hypothesis will be whether the students studying 20 minutes per night, every night, get higher scores on the test. To test the hypothesis, Mr. Montanari needs to do a survey of his students to find out the time of study and the duration of study before the examinations. By analysing and interpreting the data, he can either reject or accept the hypothesis. Hypothesis will get rejected:
1. when there's at least one case where the individual might have not studied before the examination but still managed to score the highest.
2. when there's at least one case where the individual might have studied in the day time but still managed to score the highest.
3. when there's at least one case where the individual might have studied for 20 minutes per night for every night but got an average score in the test.
The correct answer is C, Oxygen.
During aerobic cellular respiration, oxygen combines with hydrogen ions and water is released as a by-product of respiration.
Explanation;
Cellular respiration allows organisms to release energy stored in chemical bonds of glucose, and other nutrients. The energy in glucose or other nutrients such as fats is used to produce ATP, which cells use to supply their energy needs. During aerobic respiration (in presence of oxygen), oxygen is reduced and water is produced together with carbon dioxide as by-products.

be a bacteria because of it.
