In 1859, Louis Pasteur designed an experiment to address spontaneous generation. He used a curved-neck flask that allowed the air inside the flask to mix with air outside the flask, but prevented solid particles, like microorganisms, from entering the body of the flask. Broth boiled inside the experimental curved neck flasks remained clear for up to a year. But when Pasteur broke off the curved necks, the broth became cloudy and contaminated within a day. Pasteur reasoned that the contamination was due to microorganisms in the air. Based on the results of Pasteur's experiment, formulate a conclusion regarding the expected results in the third flask?
