Scenario: Physiological phenomena are complex and involve many temperature-dependent physical and chemical processes. The rate of a physiological process increases as the temperature rises until a point is reached at which the biological system involved is damaged. For most physiological processes, the rate generally increases by a factor of between two and three for each 10°C increase within the temperature range the animal can tolerate (its physiological range). This task is designed for you to explore the effects of temperature on these biological rate processes in an ideal model organism, Daphnia sp., by measuring heart rate. Task: You are required to write a short scientific report based on the practical investigation (Practical 3) into the effect of temperature on Daphnia sp. heart rate. This should include all conventional sections, namely the abstract, introduction, methods, results and discussion. Appropriate references should be included in the reference list that follows the discussion.
