help please i will medal and fan
1. Explain how this experiment disproves the theory of spontaneous generation. (3 points)

Answer 1

Instructions: Read the article below and answer the following questions.
"Francesco Redi was a scientist that performed an experiment to determine whether maggots formed from rotting meat. Versions of his experiments are described below.

Meat was placed in two beakers. One of the beakers was left open to the air. The other beaker was covered with a fabric that only allowed air to get in. As the meat rotted, flies landed on the meat in the open beaker but were unable to get to the meat with the fabric over it. After a few days, maggots appeared on the meat in the open beaker, but not in the closed beaker.

In the next experiment, rotting meat was placed in two beakers. Dead flies were placed in one beaker, and live flies were placed in the other beaker. Both beakers were sealed, allowing no air in. Maggots appeared in the beaker with live flies, but not in the beaker with dead flies."

Answer 2

First, Redi found that flies only came from flies. Specifically, if he allowed meat to be exposed to flies, then maggots developed. If he put the meat under a mesh so that flies could not reach the meat, no maggots were seen in the meat. Thus most people then assumed that large animals only were produced by reproduction.

Next, there was a discussion on whether bacteria were spontaneously produced. Louis Pasteur showed that a sterilized broth, even if it were to be in contact with the air (through an ingenious "s" shaped open tube that trapped bacteria before it got to the broth...like the trap in your sink) would remain free of bacteria.

So.... the above as well as the discovery of the periodic table about the same time as Pasteur (showing the world was real, that atoms were real, that matter was real), better microscopes (leading to the cell theory), and really just common sense finally convinced people that under present conditions on earth, life does not arise spontaneously.
