I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then

Everything Happens For a Reason Both The Odyssey by Homer and Oedipus Rex by Sophocles‚ were based in the context of ancient Greek culture but each was written during different time periods. The Gods played an enormously influential role in the lives of the Ancient Greeks. The Odyssey was written during the Greek Heroic Age (1500-1100 B.C.E.) and Oedipus Rex was estimated to be written around the 430s B.C.E. during the Age of Pericles when Athens was at its height of political and cultural power

Effect of Temperature on Cricket Respiration Crickets are ectotherms that rely on their environment as a source of heat for their metabolism. Warmer temperatures allow crickets to respire at a greater rate.

The objective: In this experiment‚ I decided to find out how temperature would affect endothermic reactions compared to exothermic reactions. An endothermic reaction absorbs energy in the form of heat. This reaction feels cold because it is taking heat away from its surroundings. It also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice

Question 1: A 50 mm diameter‚ thin wall metal pipe covered by 25 mm thick layer of insulation (ki = 0.085 W/m.K) and carrying a superheated steam at atmospheric pressure is suspended from the ceiling of a large room. The steam temperature entering the pipe is 120 oC‚ and the air temperature is 20 oC. The overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and

The Effect of Temperature on the Enzyme Catalase Stephen Francis Biology 183 Abstract This experiment was performed to determine the resultant effect of temperature change on the reaction between the enzyme catalase and hydrogen peroxide. This experiment was performed by measuring and comparing the amount of oxygen bubbles produced and the absorbance of the catalase and hydrogen peroxide solution over time at room temperature‚ 2°C‚ 50°C‚ and 60°C. The overall result of this experiment proved

Effect of temperature and humidity on the transpiration rateof the whole mushrooms P.V. Mahajan * ‚ F.A.R. Oliveira‚ I. Macedo Department of Process and Chemical Engineering‚ University College Cork‚ Ireland Abstract Water loss or transpiration is an important physiological process that affects the main quality characteristics of fresh mushrooms‚such as saleable weight‚ appearance and texture. A loss in weight of only 5% may cause fresh produce to lose freshness and appear wiltedand it is an

Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers

part of the treaty had to get involved. Alliances get nations involved even though the other nations might not want to get involved. In alliances the countries should get ready to fight immediately if one of their allies has gone to war. In World War 1 alliances changed everything. In 1914 Austria-Hungary declared war on Serbia. The reason was due to a Serbian resident who decided to kill Archduke Franz Ferdinand. This war could have been between two countries only and it

WHAT HAPPENS WHEN DOGS ARE LEFT IN CARS? There are many occasions when we make the mistake of leaving our dogs inside the car when we do errands or if we simply buy something from a convenience store. We think that it is safe for our dogs to be inside the car as he cannot run and get hit by another moving car‚ safe from being lost‚ or from any other incidents that may arise. But is he really? What happens when dogs are left in cars? Are we sure that they are safe? No. Parked cars are considered
