Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of plants’ stems. which is most likely to result in the greatest amount of error in their scientific experiment?

In doing research or experiments, it is necessary that the variables applied on the test subjects are the same. In the problem, the factor that will most likely result in the greatest amount of error will be the plant subjects. Different plants have different growth rates, and their growth can be affected by the many variables such as sunlight, disturbance, location, etc.

The correct answer is  "c".  it is "c" because melting is an endothermic change, and endothermic get's energy from surroundings.
