Question

in 1668, francesco redi did experiments to study the idea of spontaneous generation. he put pieces of meat into identical jars, that 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 with meat in jars (open, sealed, gauze - covered) was to test spontaneous generation. The first option states maggots come from fly eggs, not spontaneously. The second focuses on air for spontaneous generation, but Redi's setup was about fly access. The third is about flies from meat with air, but Redi's key was testing if maggots (larvae) come from spontaneous generation or fly eggs. So the first option matches his hypothesis.

Answer:

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