Chаnges in envirоnmentаl cоnditiоns in freshwаter ecosystems are known to have profound effects on certain species, resulting in phenotypic changes, reductions in offspring, and potentially death. Daphnia magna, which are aquatic, invertebrate filter feeders, can be affected by a variety of disruptions due to their inability to escape unfavorable conditions. Researchers suspected that exposure to abrupt increases in salinity would cause an increased heart rate in D. magna because of increasing osmotic stress. A single species, D. magna, was exposed to varying levels of salinity (parts per thousand (ppt)) with five treatment groups and a control. Heart rate (beats per minute (bpm)) was measured using microscopic observation for a timeframe of one minute. Data analysis indicated a higher than average heart rate at the lowest salinity value with a subsequent decrease at each succeeding salinity increase. The results emphasize the importance of environmental monitoring to employ best practices within the area of lake management to prevent adverse impacts on overall food web structure. Using information from the experiment, answer the following questions: 1. Based on the information given, which of the following statements accurately describes the dependent variable? [A] 2. Which of the following represents the controlled variable for the environment? [B] 3. Which of the following statements represents the conclusion of this study? [C]
