Sarah wanted to find out if temperature has an effect on the growth of bread mold. She grew the mold in nine Petri dishes containing the same amount and type of nutrients. Three were kept at 0 C, three were kept at 90 C, and three were kept at room temperature, 27 C. The containers were examined and the growth of the bread mold was recorded each Friday for five weeks. Which of the following is her hypothesis? * If there are different types of nutrient used, then that will cause difference in the amount of bread mold. If the temperature changes, then the amount of bread mold will change. If the amount of nutrients is changed, then the amount of bread mold will change. If the number of containers change, then the amount of bread mold will change.
