- Question 21>In 1668, Francesco Redi performed a series of experiments on spontaneous generation. He began by putting similar pieces of meat into eight identical jars. Four jars were left open to the air, and four were sealed. He then did the same experiment with one variation: Instead of sealing four of the jars completely, he covered them with gauze (the gauze excluded the flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (young flies) appeared in the meat.What hypothesis was being tested in the initial experiment with open versus sealed jars?A.The type of meat used affects the likelihood of spontaneous generation.B.Spontaneous generation can occur only if meat is exposed to air.C.Spontaneous generation is more likely during the long days of summer.D.Maggots do not arise spontaneously, but from eggs laid by adult flies.QUESTION 8 Morphological differences are abundant among many species.
