Fermentation in the Conversion of Milk to Kefir Authors: Michael Ahrens‚ Nicholas Fiore‚ Garrett Hages‚ Melissa Cullom University of Kansas‚ Biol 402‚ Fall 2014‚ 3:00pm room 6040 Abstract: In this experiment milk was fermented into Kefir‚ then a series of tests were used to confirm that fermentation actually occurred. The tests used to confirm the fermentation were a gas production test‚ pH test‚ Gram stain‚ and turbidity test. The results showed during the conversion of milk to Kefir there was

Abstract The major objective of this experiment was to observe the effects of catalase under varying controlled conditions. The scope of this experiment includes Metabolic processes‚ such as cellular respiration‚ and it poisonous byproduct hydrogen peroxide. The methodology includes procedures; multiple variables were tested in specific concentrations; that test the reaction rates of the enzyme catalase over a fixed period of time. The major conclusion was that catalase reacts faster in warm temperatures

one of the tests‚ so that data is lost. Specific errors include measuring the entire test tube from top to bottom instead of measuring the exact distance traveled by the filter paper‚ making the test results not plausible. The results of this lab proved several things. The results of the first test show that a higher enzyme concentration causes a faster rate of the substrate being broken down. This means that the effect of enzyme concentration on enzyme activity is a positive effect and speeds

Collecting Photosynthetic Rates in Spinach (Spinacia oleracea) Introduction: The purpose of this study was to see which light color would cause the spinach sample to photosynthesize the most within the given time. In order to understand photosynthesis‚ we need to know that chloroplasts absorb light energy from the sun‚ the plant then takes that energy along with water and carbon dioxide and changes it to sugar and oxygen. This happens in order for the plants to grow. But‚ light energy comes in a

Clement Organic Chemistry 2423‚ Section 304 25 October 2017 Lab 6: Natural Products I The main goal of this experiment was to employ isolation techniques to derive chemicals from two different natural sources and study their properties (Clement 91). The two natural sources used in this experiment were an orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol

The objective of the deicer lab was to successfully conduct experiments to determine the usefulness of magnesium chloride as a deicer. To find how successful magnesium chloride is as a deicer‚ experiments were conducted to determine the freezing point depression‚ enthalpy of dissolution‚ the impact on the surrounding environment‚ and also the expenses of using magnesium chloride as a deicer. For magnesium chloride to be determined as a good deicer‚ the reaction with water needs to be exothermic so

INTRODUCTION As for the visual documentation of a living or dead specimen‚ digital photography has largely replaced traditional illustrations of the living specimen as the standard method of recording the colour and anatomy of the specimen in the field today. Earlier traditional illustration (coloured and black and white) are still considered scientifically important because they can stress fine anatomical features that are often obscured by liquid. Even today‚ these earlier traditional illustrations

Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

things‚ that if the force of the egg doesn’t have something to fall into‚ like cotton or balloons‚ then it will break‚ because the force needs to be shared or it takes over the egg. With that‚ I understood a basis of how the device should be. This lab is designed to be very innovative with making devices so that nature can be defied. An egg that is supposed to break on contact from seven meters up will be safe and won’t break. The egg drop showcases endless laws of physics‚ and it also encourages
