(6 points) A friend asks you: “Do bacteria arise by spontaneous generation?” You answer “No” and that “Life only arises from other life”. You tell your friend that bacteria are cells and alive and can multiply in enriched beef broth. To illustrate and demonstrate that spontaneous generation does not occur you design and perform the experiment shown in the table. As part of your explanation answer the following questions: Why was the broth boiled? What predictions can you make about the growth of microorganisms in each flask? What is the basis reason for each prediction as related to the experimental condition? What are controlled variables, why they are important, and describe at least two controlled variables in the experiment? What is the purpose of a positive control in an experiment, which flask is a positive control and your reason? How do the experimental results refute the doctrine of spontaneous generation of bacteria? 3 Flask 1 is open to the air Flask 2 is sealed so that no air enters Flask 3 has a Flask 4 is a swanhorizontal neck that is neck flask left open to open to the air, but the air the air entering is sterilized The broth in the flasks was boiled to sterilize it 7.
