Question

In the mid-1600s, Francesco Redi performed a classic experiment to test the concept of spontaneous generation. As a control, he placed rotten meat in two open containers. The experimental jars also contained rotten meat, but he covered the openings with pieces of cloth. Flies landed on the meat in the open jars, but were not able to reach the meat under the cloth. Over time, maggots covered the meat in the control jars, but no maggots appeared in the experimental jars. Which of the following did Redi's results most likely show?
