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 oC, 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 would NOT be a sultable way to measure growth of bread mold in this experiment?
the diameter of the bread mold spots
the color of the bread mold spots
the number of spots of bread mold
the size of the bread mold spots
