Student V and student W wanted to do metabolism experiments with student V doing a fermentation experiment and student W doing an aerobic respiration experiment. Student W used 6 test tubes with balloons tied to the top of each test tube, but in each test tube student W put germinated beans. Student W used the same temperatures as student V. After 45 minutes, student W noted that there was no inflation of any balloon. Why did this happen?

IS IT A FACT OR A BLUFF? 1. Bacterial genetic material is composed single stranded DNA as compared to human DNA which is double stranded. 2. Just like humans, all microbes need oxygen to grow and reproduce. 3. There are no living microbes in volcanic vent and in hot spring because microbes die at very high temperature. 4. Most bacteria growth is retarded at low temperature. 5. Bacterial ATP production happens in the mitochondria which is the powerhouse of the cell. After identifying your answer whether fact or bluff, you need to give justification to your answer. You Justification should be given in not more that 50 words.
