Investigating the effects of Caffeine on the heart rate of Daphnia Shrimp. Aim: In this experiment we are trying to find out how varying the concentration of caffeine can affect the heart rate of Daphnia shrimp. Prediction: I predict that caffeine will increase the heart rate of the shrimp . Introduction: I believe the results will comply with my prediction. Caffeine is a compound found in especially tea and coffee plants and acts as a natural pesticide. Caffeine is a central nervous system

Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around

the mission was to launch the second part of the TDRS-B to improve the older version. A TDRS-B is a satellite that transports data from space to Earth. It was also supposed to have the first non-astronaut in space for the Teacher in Space Program. But 73 seconds into the launch the Challenger exploded killing all seven crew members. It will still continue to be known as a great disaster in NASA that affected many of their ways of doing things. The purpose of the Challenger mission was to improve

The question being answered was what kind of effect the increase in concentration of Convollaria roots had on the rate of fermentation. The hypothesis was that the antimicrobial activities in Convallaria majalis’s roots would hinder the process of yeast fermentation because it will cause self- destruction or death in the

Hypoglycemic Effect of Kyllinga Triceps in STZ Induced Diabetic Rats Kyllinga triceps is a medicinal plant found in India.The present study was conducted to evaluate the hypoglycemic activity of the plant in Streptozotocin (STZ) induced diabetic rats. These diabetic rats were given Kyllinga triceps extract (KTE‚ 100mg/kg & 200mg/kg) and Glibenclamide (0.5mg/kg) for 28 days. The effects of both treatments on the body weight and blood glucose were determined. Both doses of extract and Glibenclamide

Jamaica Kincaid supports the idea of the imperialists attempt to delete indigenous native culture in “On Seeing England for the First Time” where she speaks about how the big breakfast that “no one [Kincaid] knew liked eating” was “Made in England” and therefore implemented into their culture.
