The theory of spontaneous generation was a theory that was supported over time by new facts and data. b theory that was never tested. c theory that was disproved by redi and pasteur d theory that can never be disproved

The correct answer is (c) The theory that was disproved by Redi and Pasteur.

Pasteur disproved this theory wrong by performing an experiment; he invented the swan-necked flask to create an environment in which the organisms cannot grow. After sterilizing a nutrient broth in these flasks, he removed the swan necks of the controls to allow the growth of organism. Microorganisms grew only in the controls, not in the swan necked flask. This disproved the theory of spontaneous generation.

Redi stated that the theory is valid by showing the growth of maggots on the meat piece. He stated that the growth of maggots is only possible when the flies layer eggs on the meat. This also disproved the theory of spontaneous generation.

d bonding propertys
