Describe what biologists do —that is, how they approach problems and why they do experiments. Use the following information when answering the corresp onding question(s). In 1668, Francesco Redi did 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 experi ment with one variation: Instead of sealing four of the jars completely, he covered them with gauze (the gauze excluded flies while allowing the meat to be exposed to air). In both experiments, he monitored the jars and recorded whether or not maggots (you ng flies) appeared in the meat. 32) What hypothesis was being tested in the initial experiment with open versus sealed jars? A) Spontaneous generation is more likely during the long days of summer. B) The type of meat used affects the likelihood of sponta neous generation.
