This scientist experimented with raw meat:one was sealed and the other was left to be exposed to flies; maggot growth was observed ONLY in meat that was exposed.
A
Francisco Redi
B
Antony Von Leewenhoek
C
Louis Pasteur
D
John Needham
Explanation: 

Detailed explanation-1: -Redi went on to demonstrate that dead maggots or flies would not generate new flies when placed on rotting meat in a sealed jar, whereas live maggots or flies would. This disproved both the existence of some essential component in once-living organisms, and the necessity of fresh air to generate life.

Detailed explanation-2: -In 1668, Francesco Redi, an Italian physician, did an experiment with flies and wide-mouth jars containing meat. This was a true scientific experiment-many people say this was the first real experiment-containing the following elements: Observation: There are flies around meat carcasses at the butcher shop.

Detailed explanation-3: -In 1684, Redi published a book called Observations on living animals that are in living animals where he included drawings of over 100 parasites and the locations they were found. The theory of spontaneous generation states living organisms arose from nonliving material and was a widely accepted theory.

Detailed explanation-4: -In 1668, Francesco Redi published the first set of experiments challenging spontaneous generation. In these experiments, he demonstrated that maggots arise from the eggs of flies rather than directly from rotting meat. He did so by taking several jars and placing raw meat inside of them.
