Daphnia and ethanol
Webalcohol will block neurotransmitters, thus inhibiting neurotransmitters and decreasing heart rate. Similar results were seen in an experiment testing the effects on the ventricles of rats. The introduction of ethanol both decreased the frequency of heartbeats (Bebarova et al. 2010). A possible theory on why alcohol decreases activity is due to http://www.ss-pub.org/article/study-on-the-effect-of-alcoholic-beverages-on-the-heart-rate-of-daphnia-daphnia-magna/

WebDaphnia, also known as water fleas, are small aquatic crustaceans that are commonly used as model organisms in scientific research. One area of research involving daphnia is the effect of ethanol on heart rate. Ethanol, also known as alcohol, is a psychoactive drug that is commonly consumed in beverages such as beer, wine, and spirits. WebThe ethanol increased the Daphnia’s BPM from the control being 268.5 to resulting in 333 BPM. I believe that the reaction to ethanol should vary depending on the Daphnia. However, in most cases the ethanol should have decreased the BPM of the Daphnia. 3. What effect did caffeine have on the Daphnia? Why?
