- How did louis pasteur help disprove spontaneous generation?What would the results of Pasteur's swan-neck flask experiment have looked like if they supported the theory of spontaneous generation? B. What did Pasteur's experiments not prove? C. How would the presence of endospores in Louis Pasteur's nutrient solutions have affected his conclusions about spontaneous generation?How did the experiments of Redi and Pasteur refute the hypothesis of spontaneous generation?
- John Tyndall mostly duplicated Pasteur's spontaneous generation experiments with the swan-necked flask: occasionally however, an experiment failed due to A) Othe absence of nutrients B) O the appearance of dust. C) O the presence of fermentative microbes. D) O the lack of oxygen. E) O the presence of endospores.Why was Van Leeuwenhoek's discovery of the unknown such a milestone achievement for the progress in microbiology?Who were Robert Koch and Louis Pasteur?
- Choose the false statement: (Regarding Pasteur’s famous experiment) The swan necked flasks were important because they allowed the broth to remain sterile, while still remaining open to the atmosphere. Pasteur’s work with the swan neck flasks was only of importance to the food industry; his work occurred long before anyone, including Pasteur, had any awareness that diseases could be caused by microscopic agents. The swan necked flasks were used to prove that life could only arise from pre-existing cells.What are the control group in the swan neck experiment of Pasteur and what did it show?What does the theory of spontaneous generation propose? How did Pasteur, Tyndall, and Cohn finally settle the spontaneous generation controversy?
