Explanation:

1. The scientific method steps include problem - question, research, hypothesis formation, testing, and conclusion. Asking others for opinion is not a core step.
2. Redi's experiment aimed to disprove spontaneous generation regarding maggots in meats. His problem was whether spontaneous generation was a valid explanation for maggots in meats.
3. Redi hypothesized that maggots come from eggs laid by flies, not spontaneous generation.
4. He tested his hypothesis by having a controlled experiment with two jars, one covered and one uncovered.
5. The variable in his experiment was the covering of the jars (one covered, one uncovered).
6. Redi concluded that living things come from other living things, disproving spontaneous generation.

Answer:

3. b. Maggots come from eggs laid by flies.
4. a. He placed food in two jars, covering one jar and leaving the other uncovered.
5. b. Covering one jar and leaving the other uncovered.
