question 92

Multiple Choice

In 1668, Francesco Redi did some experiments to disprove spontaneous generation. He began by putting pieces of meat into identical jars. Some jars were left open to the air, and some were sealed. He then did the same experiment with one variation: instead of sealing the jars completely, he covered them with gauze (which kept out flies while allowing the meat to be exposed to the air) . In both experiments, he checked if fly maggots appeared in the meat or not. What hypothesis was being tested?

• A) Spontaneous generation is more likely to occur during the hot days of summer.
• B) Maggots do not arise spontaneously but from eggs laid by adult flies.
• C) The type of meat affects whether spontaneous generation occurs.
• D) Spontaneous generation can occur only if air is present.
• E) Flies will develop from rotting meat if the meat is exposed to air.
