How did Louis Pasteur's experiments lead to new scientific understandings of germs? Experiments with cooking food showed that disease-carrying germs in food could be killed when heated.
Experiments with different magnification lenses showed that germs were real and could be observed.
O Experiments with animals showed that dominant genes could lead to risks of disease.
Experiments with shallow dishes showed that groups of germs could be grown so they could be seen without
microscopes

The correct answer is : Experiments with cooking food showed that disease-carrying germs in food could be killed when heated.

Explanation:

Louis Pasteur's experiment with cooking shows that the microbes or germs that cause spoilage of food and disease after eating to an individual, could be killed by the heating process.

His experiment shows that microbes cause food and liquid spoilage which can be prevent by the process of the pasteurization or heating that kill such germs.

Thus, the correct answer is - Experiments with cooking food showed that disease-carrying germs in food could be killed when heated.
