Answer:

Hi There! :P

Explanation:

A controlled experiment is simply an experiment in which all factors are held constant except for one: the independent variable.

Which statement describes Redi's experiment, which helped disprove spontaneous generation?
Lelu [443]

Answer:

He examined covered and uncovered meat to determine that maggots came from eggs.

Explanation:

Prior to Redi's experiment and other supporting experiments, it was formerly believed that life could emanate from non-living things, for example, the generation of maggots from rotting meat.

In 1668, a scientist called Francesco Redi disproved the idea of spontaneous generation. He did this when he experimented that the maggots from meats are only as a result of eggs laid by flies when they perched on the meat.

He placed the meat in two jars; an uncovered jar and another in a covered jar with a cloth, after several days, the uncovered jar had maggots on the meat, while the covered jar had no maggot on the meat, but on the cloth. With this experiment, he was able to demonstrate that the maggot arose from the eggs of the flies, not the meat itself which is nonliving and hence, disproved the idea of spontaneous generation.
