Question

the passage below describes an experiment. read the passage and then follow the instructions below. dillon mixed bacteria into a nutrient - rich liquid where the bacteria could grow. he poured four ounces of the mixture into each of ten glass flasks. in five of the ten flasks, he also added one teaspoon of cinnamon. he allowed the bacteria in the flasks to grow overnight in a 37°c room. then, dillon used a microscope to count the number of bacteria in a small sample from each flask. he compared the amount of bacteria in the liquid with cinnamon to the amount of bacteria in the liquid without cinnamon. identify the question that dillons experiment can best answer. does temperature affect how much bacteria can grow in liquid? do more bacteria grow in liquid with cinnamon than in liquid without cinnamon?

Explanation:

Dillon's experiment has two groups - one with cinnamon added to the liquid and one without. He compared the amount of bacteria in both types of liquid. So the question it can best answer is about the effect of cinnamon on bacterial growth.
