The experiment was done to reveal how workouts supplements like C4 can affect the development of humans. Other experiments like this one can also be used to show how some substances may affect the development of humans. In the experiment the independent variable was the amount of the C4 that was placed into each well in the experiment, and the dependent variable was the zebrafish embryos after they were exposed to the C4. In addition, 2 controls were set up, containing a ocean/embryo solution, and the control was used to compare the effects between the solutions containing C4 and the solutions containing no C4. Furthermore, 2 controls were used because 2 experiments were conducted one containing a larger solution of C4 and the other containing a trace amount of C4. The hypothesis stated that if the zebrafish embryos were exposed to concentrations of C4, then there would be a higher mortality rate in the groups containing concentrations of C4. The hypothesis …show more content…
Also, some of the the zebrafish in the control group died, which was peculiar as to why they died if they weren 't exposed to anything. The control group had the highest survival rate compared to the groups containing C4, and the lower concentration groups had more surviving zebrafish embryos than the higher concentration groups, which had no living zebrafish embryos. In addition, the experiment produced only one hatched zebrafish, which was found in the 0.32 mg/mL concentration of C4. The exact cause of the massive die off of the zebrafish embryos is unknown. In the deceased embryos there was no movement inside of them and the pigment was darker than the surviving embryos. The surviving embryos had a rapid heart rate which was observed in the embryos, it was hypothesized that they could have died from the pre longed rapid heart rate that was
