the 200mL beaker started with an average temperature of 43.5oC it then gradually fell to 41oC after 45 seconds‚ then rapidly decreased in temperature by 2oC every 15 seconds. At the 90 second period it decreased by 4oC from 35.5oC to 31.5oC it then steadied out falling by 1oC per 15 seconds until the 120 second stop mark. For the 500mL beaker the temperature difference between the 15 second intervals were very different being more gradual with the temperature on average falling from 1 – 1.25oC per

Purpose Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries‚ even when the surrounding temperature varies and is of higher or lower temperature than what is normal. The purpose of thermoregulation is to balance thermal inputs and thermal losses in the body so as to maintain a relatively constant core temperature of approximately 36.7 degrees celsius. If this was unable to take place the body may not be able to functions properly and it could result

Sex Education in the Philippines Basically‚ it is one of the few words that catch our attention. Whenever we see the word “sex” in magazines‚ newspapers and other print materials‚ we tend to stop at some point and become interested to read the article where it is written. It’s not because we simply feel the urge to read about sex but perhaps the “questioning self” wants to clarify and discover the truth about this matter. In liberal democracies‚ sex is viewed as a normal activity for both adults

Thermochemistry Thermochemistry is the study of heat evolved and absorbed during the chemical reactions. The system is the interest of the universe; the surroundings are the rest of the universe in which the exchange of the energy with the system takes place. Both‚ the system and the surroundings make up the universe. Heat flow is the transfer of heat from a warm place to a cooler one. System to surroundings: Surroundings to system:

The Empirical Formula of Magnesium Oxide. Focus Question – Can the mass of magnesium combusted in excess oxygen be used to determine the empirical formula of magnesium oxide? Hypothesis – Combustion of Magnesium will generate data which can be used to calculate the EF of Magnesium Oxide Experimental Report: Data Collection and Processing Qualitative Observations: * The Magnesium burnt with a very bright flame. (as seen in figure 2 below) * White smoke was formed and some

To investigate the effect of different caffeine concentration on the heartbeat rate of Daphnia at room temperature. Introduction: Caffeine is found‚ and produced in many plant species to function as a natural pesticide‚ and as an inhibitor of seed germination of other nearby coffee seedlings to give it a better chance of survival. Caffeine is able to paralyze and kill certain insects upon feeding on the plants that produce caffeine. Coffee‚ tea and cocoa are common caffeine-containing

How does temperature affect the rate of reaction for Lipase? As the temperature increases‚ so will the rate of enzyme reaction. However‚ as the temperature exceeds the optimum the rate of reaction will decrease. I predict that at temperatures above 70°C the enzyme lipase will become denatured and at temperatures below 10°C the enzyme will become inactive. Since lipase operates within the human body I’d also predict that its optimum temperature would be around human body temperature which is approximately
