Question

the passage below describes an experiment. ryan 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. then he added one teaspoon of cinnamon to five of the flasks. ryan allowed the bacteria in the flasks to grow overnight in a 37°c room. the next morning, he 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 in the liquid without. identify the question that the experiment can best answer. do bacteria change color when mixed with a liquid with cinnamon or a liquid without cinnamon? do more bacteria grow in liquid with cinnamon or in liquid without cinnamon?

Explanation:

Step1: Identify the variables

The variables are presence of cinnamon and amount of bacteria growth.

Step2: Determine the research - question

The experiment aims to compare bacteria growth in liquid with and without cinnamon, so this question best fits the experiment.

Answer:

Do more bacteria grow in liquid with cinnamon or in liquid without cinnamon?
