Temperature affecting enzyme activity Aim: To see how temperature can affect enzyme activity Prediction:-I think the one that will work best will be the rennin placed in milk at 37oC My independent variable will be the temperature My dependant variable will be how thick the milk becomes The equipment I need is milk‚ 5 test tubes‚ rennin‚ water bath‚ boiled rennin‚ a glass rod and a stopwatch Introduction: Rennin is an enzyme found in the stomach‚ its function is to solidify milk.

Assignment – Physics 1 1. Two carts‚ one twice the mass of the other‚ experience the same force for the same time. What is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact

How one responds to a situation is a huge factor that contributes to personal happiness‚ for the state of happiness is achieved from accomplishing a certain goal. In the 18th century‚ the 13 colonies was in feud with its mother country‚ Britain; refusing to pay taxes without representation. George Washington‚ the General of the Continental Army‚ was hopeless and at the brink of surrender. Yet through the motivational articles such as Paine’s Common Sense‚" the establishment of the Declaration

You might have thanked the trees for giving oxygen but never phytoplankton. What can they do except try to steal the Krusty Krab formula? Well‚ what if I said that without phytoplankton‚ the entire marine ecosystem collapse‚ an increase of 1/3 accumulation of CO2‚ and oxygen drop up to 50 percent in the atmosphere‚ which will lead to human extinction. Sounds dramatic‚ but it is true. I seriously think that we need to care more about these planktons‚ since they are not unlimited in the ocean‚ and

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

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

STEP 1 – SWING FUNDAMENTALS BALL FLIGHT LAWS The five physical laws of ball flight are invariable‚ no matter who swings the club or where or how a club contacts the ball: • Clubhead speed - The speed a club is travelling when it makes solid contact with ball determines how far the ball will go. • Clubhead path - A ball’s starting direction is determined in part by the line along which the clubhead swings as it contacts the ball. • Clubhead face - The direction of a ball is determined in part by

The Effect of Temperature on Blow-fly Larvae INTRODUCTION Calliphoridae- comonly known as a blowfly‚ are living organisms which usually are the first insects to colonise a body after death. The blowfly larvae are very useful in forensic entomology. The oldest larvae give an approximate time of death of body. Family: Calliphoridae Order: Diptera Name: Calliphora vicina Aim: To check the influence of temperature of environment on living functions and activity of Blow-fly larvae.

PRACTICAL 3 QUESTIONS PART 1 Q 1. What is the diameter of the field of view of your microscope using the x10 objective (i.e. at a magnification of x100)? The diameter of the field of view using the x10 objective is 1800 µm. Q 2. What is the diameter of the field of view of your microscope using the x40 objective (i.e. at a magnification of x400)? The diameter of the field of view using the x40 objective is 400 µm. Q 3. What is the ratio of magnification between the x10 and x40 objectives?
