Multiple Choice

Please use the following information to answer the question(s) below.
The contamination of soils with heavy metals has become more common as a result of the burning of fossil fuels, industrial activities, and agricultural fertilizer application. These heavy metals can be toxic depending on the concentrations that accumulate in an organism. A scientist hypothesizes that biological magnification of heavy metals in fragment-dwelling, insect-eating birds should be greater in forest fragments with relatively more edge habitat because edge-dwelling bird species may forage for insects in contaminated areas outside of the forest. Forest fragments with more interior habitat would not have as much biological magnification because insect-eating interior bird species would have less exposure to insects that contain heavy metals.
-The scientist finds that the heavy metal concentration in the insect-eating birds of a fragment does not depend on the relative amount of edge habitat of that fragment. Which of the following describes how experimental error may have influenced the results?
