prepared for the experiment‚ one at room temperature and the other two at 15°C and at 5°C. The room temperature water bath was prepared by filling a basin with tap water about ¾ full so that when the subject’s face is submerged‚ the water will not spill. A thermometer was used in order to obtain the temperature of the water. The temperature obtained was at 26°C. The water baths having temperatures of 15°C and 5°C were also prepared the same way as the room temperature water bath only with the addition of

What effect does temperature have on the oxygen production of enzymes in an animal’s liver? A temperature which is too high would be able to produce little to no oxygen because of the extreme temperature. Just like a temperature too high‚ a temperature which is too low would also produce little to no oxygen for the same reason. Animals that have livers are considered warm-blooded‚ with very warm temperatures; therefore it would make sense for a warm temperature to produce the most oxygen; but one

intricately woven into each other. Good morning respected teachers and my dear friends ...today I Nikita am going to speak about how human activities are affecting flora and fauna? We are facing a serious crisis in biodiversity‚ the variety of animals‚ plants and their habitats. We humans are part of this biological diversity and depend on it in many ways. The rate that animal and plant species are becoming extinct‚ and the pace at which ecosystems are being destroyed‚ are increasing every day. But

3 Factors that Influence Rate of Return Any bondholder‚ or any investor for that matter‚ will allow three factors to influence his or her required rate of return. The three factors are the following: real (pure) rate of return‚ inflation‚ and risk premium. These three factors equal the risk free rate which is the rate of return of an investment with no risk of financial loss. This is also the rate that investors would expect from an absolutely risk-free investment over a period of time.

solution used. This would make both my results and conclusion invalid and unreliable. I also made sure that the temperature of the water bath was at the correct temperature and I kept on checking the temperature of both my amylase‚ and starch using a thermometer. I made sure both solutions were at the same temperature at all times throughout my experiments‚ so that temperature would not have an effect on my results. This would help me obtain more reliable and accurate results. Also‚ I made sure that I was

experiment was conducted to see where these micro-organisms were present and how widespread and abundant they were. Method: In the experiment‚ there were 3 environments in which agar plates were used to get bacteria and fungi. Environment No.1 was inside the lab with the laboratory air‚ environment No.2 was outside the lab in the open air and environment No.3 was taken from scalp scrapings from the students involved. In environment 1‚ 6 agar plates were produced. The 6 plates were separated into groups

Temperature and Thermometers The Temperature of an object is a measure of the hotness or coldness of that object. An alternative way to think of temperature is to say that “the temperature of an object is a number – on some manmade scale – that indicates the hotness of the object”. ‘Hotness’ in turn is a measure of the kinetic energy of the molecules of the material. Note: You must use the term ‘hotness’.* The SI unit of temperature is the Kelvin (K)* Relationship between degrees Celsius

Effects of pH on fungal amylase activity BI 211 November 25‚ 2011 Introduction In recent years‚ the uses of microorganisms have become a huge importance to industry and sparked a large interest into the exploration of enzyme activity in microorganisms. Amylase is one of the most widely used enzyme required for the preparation of fermented foods. Apart from food and starch industries‚ in which demand for them is increasing continuously‚ amylase is also used in

Lab activity 1: Effect of temperature‚ concentration‚ and pressure on equilibrium Introduction Our ongoing discussion has been on systems at dynamic equilibrium: for a reversible reaction‚ the rate of the forward reaction is equal to the rate of the reverse reaction. What happens if equilibrium is disturbed? In this lab activity‚ we are going to examine the effect of changing reaction conditions on the position of equilibrium. Part I: Effect of temperature We will consider the equilibrium
