Science Coursework Trypsin Investigation Aim I am going to prove that temperature effects the rate in which the enzyme Trypsin breaks down milk substrate into amino acids. Investigation "We strongly recommend the use of Vanish Stain Removal Tablets in conjunction with a 900 spin wash at 70°C" This was found on a milk carton of a well-known drinks company‚ Nesquick. The major food group constituent of milk is‚ of course‚ milk. For my Science Investigation‚ I am going to test different temperatures

another; effect and reaction. The two different types of energy are kinetic and potential energy. Kinetic energy is the energy a moving object has because of its motion. The kinetic energy of a moving object depends on the object’s mass and its speed. The kinetic energy of a moving object can be calculated from this equation: Kinetic energy (in joules) = ½ mass (in kg) x [speed (in m/s)]² KE= ½ mv² In this equation ^‚ the symbol v represents speed.

Revolution”. The pre-industrial revolution period was characterized by a simple process of manufacture‚ small scale investment‚ local markets and small number of persons employed. All this led to close proximity between the manager and the managed. Due to personal and direct relationship between the employer and the employee it was easier to secure cooperation of the latter. Any grievance or misunderstanding on the part of either party could be promptly removed. Also‚ there was no interference by the

is the kinetic energy of the entire system? KETOT = KEwheel+KEweight = (1/2)(I)(w2)+(1/2)(m*v2) =(0.5* v2)(m+1/2M) =0.5*(2.2^2)*(3+(.5*15)) J b) If the system started from rest‚ how far has the weight fallen? H = KETOT/MG = 0.5*(2.2^2)*(3+(.5*15))/(3*9.8) m c) What is the angular acceleration at this point? Remember that a = αR‚ or α = a/R Solve for acceleration by using vf2=vi2+2ax (vf=2.2‚ vi=0‚ x=(answer

Vitamin C Molecule Investigation Thomas Philpott Introduction Vitamin C (ascorbic acid) is an essential component of human nutrition‚ as it is an antioxidant that the body requires. Having a deficiency in Vitamin C can lead to scurvy‚ a disease characterized by abnormalities in human bones and teeth. Fruits and vegetables are common sources of Vitamin C‚ notably oranges and citrus fruits. Cooking and the application of heat destroy the vitamin so such fruits must be raw in order to obtain the

Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with

The Reign of Edward VI The reign of Edward VI saw great religious upheaval from a Protestant religion that was Catholic in nature to a more clearly defined and radical quasi-Calvinism. In that sense religious policy hardened. But the policies and ideal never became deeply entrenched and accepted throughout the country and often only existed to serve the interests of those who enacted them‚ and not the future stance of the church. Under Somerset the changes involved merely creating a Protestant

kingships; Henry VI and Edward IV. The first kingship was an extremely weak one with Henry VI who seemed to show a clear lack of interest in ruling the country‚ and then came Edward IV who was a strong king that sorted out the mess that Henry VI had left behind. However‚ throughout both reigns‚ the nobility seemed to stay the same; the majority of them were over mighty and caused unrest. My essay is going to discuss the impact of these over mighty nobles and the impact of king Henry VI and Edward IV
