In the 1600's, the Italian scientist Francisco Redi performed experiments that showed that flies did not spontaneously generate from raw meat.
because they always appear where meat is rotting
they land on dead meat then eat it then lay their eggs upon the dead meat an lay maggots
Meat comes from animals. It has no national origin. This is like asking what country food comes from. Wherever there are animals, there is meat, and there is always something that eats it, including birds, insects, and bacteria. All carnivores and predatory animals eat meat.
The bologna meat gets its name from the city in Italy that shares its name. Since the 14th century pork meat which is was bologna is was eaten and traded.
The part of the cow that fajita meat comes from is the plate. Traditionally, fajita meat is made from skirt steaks which is made from the plate of the cow.
Redi's experiment proved that maggots do not spontaneously generate from decaying meat, but rather come from the eggs of flies. This refuted the prevailing theory of spontaneous generation.
Flies are attracted to meat and will lay eggs on the meat, where they quickly hatch into maggots. But the flies are not indigenous to the meat.
Yes, if flies lay eggs in exposed rotting meat their larva will feed themselves until developed and then turn into new flies. If the rotting meat is not exposed the flies will not be able to lay eggs and there will be no emerging flies.
Redi's experiment proved that maggots did not spontaneously generate from decaying meat, contradicting the popular belief of spontaneous generation at the time.
Redi's theory, known as spontaneous generation, proposed that living organisms could arise from nonliving matter. In his famous experiment with the meat and fly larvae, Redi demonstrated that maggots do not spontaneously generate on rotting meat but instead come from eggs laid by flies. This experiment helped to disprove the idea of spontaneous generation.
no it doesnt
Francesco Redi did an experiment in 1668 that disproved a belief that maggots spontaneously generated on rotting meat. His experiment was to place meat into sets of jars: one set he left open to the air, one set he covered with very fine gauze, one set was completely sealed. Maggots appeared on the meat in the open jars; flies laid eggs on the gauze but no maggots appeared because the scent of rotting meat provides no nourishment; nothing appeared on the meat in the completely sealed jars. Redi believed in spontaneous generation of many things, just not fly maggots. He is credited with beginning the experiments using controls method used now.
Flies come to it because of the smell hoping to find some rotting meat and when they land on the flower they pollinate it
Rotting meat doesn't create flies. Rotting meat attracts flies that lay their eggs on the meat. These eggs hatch and maggots emerge and proceed to feed off the rotten meat. After a period as a chrysalis, the maggots change and emerge as adult flies.
Redi did an experiment seeing what maggots come from by putting meat into jars and left 1 open 1 covered with netting and one sealed the only one that didn't get maggots was the one that was sealed proving that maggots come from flies.
Redi used a jar, meat and gauze. The gauze kept the flies off the meat. Redi's hypothesis was that if you kept flies away from the meat, maggots would not appear, because the flies did not lay eggs on the meat.
