Answer:B. Place a piece of bread in a plastic container and leave it for three days. Observe what would happen to the bread.#1. What do you see on the bread? After three days, I saw fuzzy, white stuff growing all over the bread. It looked like a thin layer of cotton. Some parts were darker, almost greenish. It smelled musty and sour.#2. What brought them there?I think tiny living things called mold spores landed on the bread. The warm and damp environment inside the container gave them the perfect place to grow and multiply, making the bread look and smell the way it did.FOLLOW M3 FOR MORE ANSWERS!
