Question

francesco has performed an experiment where he covered one jar and left another uncovered to observe what would happen, what aspect of living things did this confirm? 1. first, prepare meat to put inside the covered jar and the uncovered jar. he ensured the meat was put with a cloth that let air in. 2. after a few days, the meat in the uncovered jar was full of maggots, but the meat in the covered jar was not. there were no maggots on the cloth covering the covered jar. 3. he concluded that flies had laid eggs on the meat in the uncovered jar. the meat in the covered jar had no maggots. he knew that flies could not land on the meat in the covered jar, so they were not able to lay eggs. he concluded that maggots did not come from the meat itself and could not produce maggots.
options:

• all organisms respond to their environment
• all organisms contain dna
• all organisms use energy
• all organisms come from other organisms.

Explanation:

Francesco Redi's experiment tested the idea of spontaneous generation. By covering one jar of meat (preventing flies from accessing it) and leaving another uncovered, he showed maggots only appeared in the uncovered jar, proving maggots came from fly eggs, not spontaneous generation. This demonstrates that living organisms originate from other living organisms.

Answer:

All organisms come from other organisms.
