Size of Daphnia. Results Table #1: Effect of Temperature Variations on Heart Rate of Daphnia magna I Temperature (C) Room Temp. When the animal is warmer, the heart rate will raise – as long as the temperature isn’t sufficiently high to harm the animal. The concentration of the caffeine in the blood of Daphnia will determine the heart rate of the Daphnia. 9. Small piece of cotton wool. from COMMUNITY ECD at Kenyatta University. Controlled variables.

These are my basic results but I must disclaim that this was not done under true. The results gained from this experiment aids scientific researchers in finding out how caffeine can affect heart rate as well as human health. This results in varying demands of oxygen intake and carbon dioxide removal. Heart rate of Daphnia. Repeat procedure, raising temperature by 5 degrees each time, up to 35 degrees. The heart rate can be monitored and measured in different conditions, such as change in water temperature, or in this case, the concentration of chemicals added to the water they habitat. Predictions: • I predict that the daphnia in a higher concentration of caffeine would have the fastest heart rate as caffeine stimulates the heat therefore it beats faster It will be directly proportional to each other, meaning that the increase of the concentration of the caffeine will give an increase of the heartbeat.
