in 1668, francesco redi did experiments to study the idea of spontaneous generation. he put pieces of meat into identical jars (some were open, sealed, or covered with gauze), and observed if maggots appeared in the meat. what hypothesis was redi testing?
you can respond once
maggots do not arise spontaneously, but arise from eggs laid by adult flies.
spontaneous generation can occur only if air is present.
flies will develop from rotting meat if the meat is exposed to air.

Explanation:

Redi's experiment involved jars with meat in different states (open, sealed, gauze - covered) to test spontaneous generation. The first option aligns with his hypothesis that maggots come from fly eggs, not spontaneous generation. The second option is incorrect as his experiment wasn't about air for spontaneous generation in that way. The third option misinterprets the source of flies (from eggs, not meat directly).

Answer:

A. Maggots do not arise spontaneously, but arise from eggs laid by adult flies.
