Transcript of Zebrafish Experiment

Zebrafish There are plenty of data claiming that alcohol is bad for the human body. But what effect does it have on something as small as zebrafish? Hypothesis and Prediction if we gave zebrafish alcohol, we hypothesize that they would be affected the same way that alcohol affects humans, resulting in more living fish in the control dish than in the experimental dish containing alcohol by the end of the experiment. About the experiment Purpose :To see the effects of alcohol on zebrafish Background Info. Alcohol has been known for years for causing problems in many parts of the human body, including the brain, heart, liver, and more. Embryogenesis Although there are many positive and negative factors that affect an organism's embryogenesis, we will explore to see if alcohol will have a positive effect or negative effect on the development of zebrafish. It's so bad that even schools are requiring new, incoming freshmen to take a supercool survey/tutorial on the ways alcohol can affect our fun college lives. Experimental Design Results & Discussion 1. Hypothesis and Prediction Under the alcohol condition, development of embryonic-cell and growth would be significantly disrupted. Under the alcohol exposure, the survival rate in the experimental (alcohol) group would be lower than the control group. 2. Errors in the Experiment a. Carnivorous Protists' Invasion of culture Common Dinoflagellates are not harmful, but protists that derive their food source by heterotrophic systems obtain their nutrients by digesting other organisms. Phylum Mastigophora Phylum Sarcodina Phylum Dinoflagellate Conclusion Neither the hypothesis nor the prediction was fully supported by the results. Possible improvements could be made to avoid errors encountered in this experiment. We had two Petri dishes of Deer Park water and alcohol was added to one of the dishes. 20 supposively healthy embryos were placed in each dish. On day 4, Paramecium was added as a food source, and some of the water/alcohol was replaced with fresh supplies.
