Daphnia Chemical Heart-Rate Report
Budget: $30 – $250 USD
I have completed the experimental phase of a study that monitors the heart rate of Daphnia magna while they are exposed to a series of common chemicals. I now need a concise, publication-ready lab report that focuses on how the heart rate changes under each chemical condition.
Chemicals tested
• Alcohol
• Caffeine
• Nicotine
• A standard nasal-spray formulation
• Adrenaline
• Acetylcholine (Ach)
All raw observations are already logged in minute-by-minute spreadsheets. Your task is to turn these numbers into a clear scientific narrative:
• Summarise the protocol (Daphnia handling, microscope setup, concentration ranges, timing).
• Present the heart-rate data before, during and after exposure for every chemical, using neat tables and at least one figure per compound (Excel or R plots are fine).
• Highlight and interpret any notable increases, decreases, or recovery patterns; do not delve into advanced statistics beyond simple rate comparisons—I only need the direct change curves.
• Discuss plausible physiological mechanisms that could explain each trend, referencing recent literature where helpful.
• Conclude with a short section on limitations and suggestions for future work (e.g., temperature or light trials that I may add later).
Please deliver a fully formatted document (Word or Google Docs) plus the original graph files so I can tweak visuals if needed.
