actually does not. In most reactions C and D start to react to form A and B at a certain point as you can see in the equation c C + d D → a A + b B. These two reactions occur until the rate of reaction in both equations become equal (meaning the speed of the production of C and D in the first equation is equal to the speed of the production of A and B in the second equation) resulting in a

Research An object that is falling through the atmosphere is subjected to two external forces. The first force is the gravitational force‚ expressed as the weight of the object. The weight equation which is weight (W) = mass (M) x gravitational acceleration (A) which is 9.8 meters per square second on the surface of the earth. The gravitational acceleration decreases with the square of the distance from the center of the earth. If the object were falling in a vacuum‚ this would be

According to “Science fair projects” an enzyme becomes unstable at higher temperatures and the shape of the enzyme changes. The enzyme is also used to remove hydrogen peroxide from clothing in the textile industry. This would make sense because when an enzyme encounters a substrate molecule

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable

between temperature and light absorbance. The higher the temperature of the water surrounding the beetroot‚ the more coloured the water around the beetroot was. This is shown in the graph by: at 0°C‚ the water surrounding the beetroot was fairly pink and had an averaged amount of 0.074 absorbency. At 80°C‚ the water surrounding the beetroot was very pink almost red‚ and had an average of 0.982 absorbency. Conclusion The hypothesis was that beetroot left to diffuse at a higher temperature will have

Introduction Cell respiration is the process of a cell converting sugars into ATP (energy) in the mitochondrion. It is an essential process which enables organisms to survive and function (Biology Online‚ 2010). Not only does it produce ATP‚ but also carbon dioxide (though decarboxylation)‚ NADH and FADH and in the case of some organisms‚ alcohol. Saccharomyces cerevisia‚ a bacterium commonly known as yeast‚ is used in various aspects of life‚ from winemaking to baking. It respires both anaerobically

“A Distant Episode” written by Paul Bowles recalls the story of a professor who is captured by the Reguibats‚ a nomad tribe. As the story began‚ it focused on the professor and his journey to find an old friend; however it took a turn when the professor was turned over to the tribe. This short story has similar aspects when comparing it to The Heart of Darkness‚ by Joseph Conrad. The ideas of cultural imperialism‚ the climax and the idea of people going insane are resembled in both pieces of literature

performed to investigate the effects of temperature on the growth rate pine seedlings. Experiment 1 A batch of 60 pine seedlings (Batch I) was grown in a greenhouse under controlled temperatures. Ten plants were grown at each of six temperatures from 50 C to 300 C. These plants remained at their original temperatures 24 hours each day for two weeks. All other conditions were the same for all seedlings. The growth rates are shown in Table 1. Table 1. Growth rates for pine seedlings in Batch I Experiment

The goal of this experiment was to explore how temperature would influence the rate of cellular respiration of beans. It was hypothesized that as the temperature of the beans increased‚ the rate of cellular respiration would increase as well. In this experiment‚ the independent variable was the temperature‚ which gradually increased as time went by‚ and the dependent variable was the rate of cellular respiration‚ which was shown by the change in the amount of CO2 and O2 in the container. During the
