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.
Compare and contrast the different experiments of Refi,Needham,Spallanza,and Pasteur
Describe one experimental difference between the experiments of Spallanzani and Pasteur (i.e. what was
different between the 2 experiments in terms of their procedures).
