temperature on the enzyme activity was that the reaction’s rate would increase as the temperature increased‚ until they go over the optimum temperature where the enzymes denature and the reaction’s rate quickly drops to zero. At 5 degree C the rate is 0.00059mole PNP/min. This then increases to 0.01031mmoles PNP/min at a temperature of 50 degree C. The rate then drops drastically to -0.00215moles PNP/min. This point is where the enzymes have been denatured and have no activity‚ shown as the last point

The Effects of Force and Mass on an Object’s Acceleration Abstract: In this lab there were two principals investigated. The first was the relationship between applied force and acceleration. The second was the relationship between mass and acceleration. To study these two relationships‚ my partners and I used a dynamic cart with added mass on it. This cart was then attached to a pulley system on a “frictionless track” where it was pulled by a string bearing mass over the edge

ASSAYING PLANT SUBSTANCES FOR ANTIBACTERIAL ACTIVITY PURPOSE To test plant extracts to see if they possess antibacterial activity. PROCEDURE First create a list of plant extracts being tested and choose 2 extracts per group. The plants being tested are Oregano‚ Tea tree‚ Eucalyptus and Colloidal Silver. Obtain two nutrient agar plates and using a permanent marker draw four quadrants on the bottom of each agar plate. Using a sterile pipet transfer 250 ml of E. coli broth to the middle of

Explain what is meant by this phrase. This means that once the threshold is met‚ an action potential occurs. If the stimulus is too small an action potential does not occur. An action potential is usually initiated in an axon at or near what? The axon hillock‚ the initial segment‚ and the trigger zone. The adequate stimuli

Introduction The purpose of this experiment is to determine whether a change in mass affects the acceleration of the cart. The independent variable is the mass of the weight and the dependant variable is the acceleration. I do not think there is a control in the experiment because we do not know an absolute result with any of the masses of the weight. Besides‚ if we used 0g as our control‚ the cart won’t even move. Hypothesis Under these conditions I believe that the results shown in the distance

Introduction The Disbursement Acceleration Program of the Aquino Administration should not be implemented because it does not contribute in the GDP and economic growth of the country‚ although it may have been partially successful‚ its rediscovery has drawn reaction as “Unlawful”‚ aside from being unconstitutional‚ it does not serve‚ neither its spending was translated to over-all increase of jobs‚ nor trigger a downturn in poverty incidence. II. Background The Disbursement Acceleration Program (DAP) is a
