Use a new glucose strip and record Data: Conclusion: According to my data, pH levels do, in fact, affect the results of Lactex. I say this because in my experiment, pre-enzyme, my solutions were all negative except for the soda. I used the test strips to determine if they were negative or positive solutions. After I put in the enzyme, Lactex, my results changed. Vinegar, Antacid, and Soap all became positive solutions after I put in the enzyme.
Caffeine & Alcohol Effect on the Water Flea Heart Rate Abstract In this study, water fleas (Daphnia magna), a semi-transparent freshwater crustacean, are used to study the effects of caffeine and alcohol on heart rate. There was a control group used along with the alcohol and caffeine to ensure the results were more accurate. The prediction was the introduction of alcohol and each increased concentration of alcohol, would decrease heart rate and the introduction and subsequent increased concentrations of caffeine would increase heart rate. The results of this experiment proved the prediction to be correct with the alcohol, but the results from the caffeine were hardly noticeable. Methods & Materials
Alcohol and Caffeine vs. Daphnia heart rate Abstract This experiment was performed to observe the effects of alcohol and caffeine on the heart rate of a Daphnia magna. There was a control group used along with the alcohol and caffeine to make sure we got accurate results. It was predicted that the increasing concentrations of alcohol would decrease heart rate and the increasing concentrations of caffeine would increase heart rate, based on pervious experiments. The results of this experiment proved the predictions to be valid and helped to make educated decisions about the effects of alcohol and caffeine in any living organism. Introduction Caffeine is a stimulant and diuretic.
As soon as the men were taken off the drug the side effects went away. The scientists concluded that the steroid was the main factor of the side effects and if the steroid was not used then there would be no side effects and changes in health. Again I used the JSTOR database to locate this journal. The results for "anabolic steroids" was so great that I decided to use it for the rest of my sources. This time I used the

Research suggests that creatine improves strength and performance in teenagers who were already in shape and highly-trained for their sport. It is safe, but users should always look at label directions and follow manufacturer's suggestions when considering creatine. Although the supplement can help build muscle, creatine has many negative affects on the human body. Studies have shown that the long term use of creatine is not healthy. It can lead to many different factors such as: chronic heart failure, heart disease, bone density, depression, dialysis, high cholesterol, spinal cord injury, or memory loss.
HYPOTHESIS : What is the Dependent Variable measured: ______________________________________ What is the Independent Variable used: __________________________________________ Predict the effect of each situation/solution on the heartbeat: Make a Hypothesis for each Cold Water Hot Water 1% Ethanol Sugar Water MATERIALS • 4 Daphnia in culture liquid (per table) • Transfer pipette • a clean depression slide • Compound microscope • a small container for “used” Daphnia PROCEDURE – follow below or the modify to YOUR teacher’s instructions Keep the light for your microscope OFF as much as possible to avoid overheating your Daphnia! 1. Using a clean pipette, carefully transfer a Daphnia and ONE drop of liquid onto a slide. Keep the drop small so that the Daphnia can’t swim out of your field of view. 2.
Screening could be the thing that could keep workplaces run efficiently. According to Santa Clara University, with having genetic screening it lowered the work-related diseases plus having the screens would also benefit society as a whole by reducing the health care costs covered by Medicare and Medicaid, public assistance, and social security payments. On the negative side of genetic screening if one was in line for a job requiring strength that wasn’t strong enough one would not get the job. This is fair in my opinion. I think that screens should occur with the interview, during the time of the job, and after the job just to be alert for what shows up and what is on the way.
The mucous tube insulates and prevents the glow worm from dehydration. At night inside the tube it moves back and forth breaking through the tube to repair its web or to feed on trapped insects. During the day the glow worm hides inside its safety haven to avoid daylight predators. Ironically the glow worm is not actually a worm but a larvae. Early settlers from the British Isles applied the common name 'glow worm' as a substitute for the English glow worm Lampyris noctiluca, which was actually a beetle.
A very minute amount of contaminated blood is enough to infect a human with the Ebola virus, so those working in the Hot Zone must always be careful for the smallest little tear that might allow it into their space suits. I enjoyed reading this book. I thought the message was exact and it kept me turning pages! I never knew what was going to happen next and just recalling in the back of my head how it was all true! How astonishing!
