An experiment to investigate the effect of temperature on the rate of reaction of the Enzyme Trypsin. Aim: This investigation was on the effect temperature has on the rate that the enzyme trypsin hydrolyses its substrate‚ a protein found in milk (casein). This investigation was conducted under controlled conditions‚ the temperature being the changeable variable. Trypsin and its substrate (powdered milk which is a source of the protein casein) were heated in a water bath. The contents of the two

Memorandum To: Urban Planning Department From: Name Subject: Rise of Temperature in Urcity Date: Introduction Agricultural areas all over the world are feeling the effects of suburb expansion. The cities growth is having an effect on the ability of land‚ water‚ and animals. With city growth will create problems such as climate‚ land‚ and geographical changes (Hillel‚ 1995). Critical Findings The agricultural areas of UrCity are being forced further out into the desert basin due

The short story ‘Spilled Salt’ is about a mother‚ called Myrna‚ whose son‚ Kenny‚ has been convicted to go to prison‚ then he comes back one day‚ and she does not know how to react about his homecoming. Myrna starts wondering how it all started and why she does not want to see her son anymore. She ends up deciding that she does not want to see Kenny again‚ and packs her stuff to go away for a week‚ and leaves a note behind for Kenny‚ saying that she does not want to see him again‚ and she wants‚

demand or increase in the pumping of freshwater wells is higher than the rate at which freshwater naturally produces. The production rate for freshwater takes time and depends on a few factors such as the climate‚ precipitation‚ surface runoff‚ and temperatures affect the rate at which freshwater accumulates. When over pumping occurs and the underground freshwater process is slow‚ ocean water replaces the absent ground water and thus areas suffer saltwater intrusion in the aquifers. Wind powered pumps

internal temperature so that the body processes can take place efficiently. The process ensures an equilibrium system is attained for all the body processes. The body temperature of an average individual is 37˚ C. this temperature fluctuates depending on activities one does. A human being is in constant movement unless they are asleep. As such‚ the temperature may increase or decrease thereby varying from this average. Some of the factors that may lead to increase in the body temperature include digestion

Abstract This experiment was designed to answer the question does temperature affect the amount of osmosis? The hypothesis predicted was that the higher the temperature the more osmosis would occur‚ but too high the osmosis would halt due to enzyme and substrate overheating and losing shape. After research and class time it was concluded that osmosis is a passive transport and would not require energy or enzymes due to it going from high to low concentrations with the gradient

Salt Marshes‚Mangroves‚and Coral Reefs Salt Marshes • Salt marshes are found along low lying coastlines where boggy ground is flooded by sea water either daily or less frequently. • Many UK salt marshes have been reclaimed for farm land‚ but those that remain provide valuable habitats where salt-tolerant plants grow and birds nest. Salt marshes also pay a vital role for coastal protection‚ they contain creeks which allow tidal waters to flow both in and out which reduces the wave energy

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 what distance will be required for the steam to reach a mean temperature of 100 oC? Question 2: Consider a horizontal‚ thin walled circular tube

Goldfish and Water Temperature Goldfish and Water Temperature The subject of my observation is a goldfish that is kept in a 2 gallon fishbowl positioned on a window side table. I have noticed that the goldfish is more active in the earlier morning and later evening than during the afternoon hours. Because the table is near a window that faces northeast‚ the fishbowl receives direct sunlight during the time between eleven o’clock a.m. and four o’clock p.m. The goldfish activity decreases around
