and bacterial amylase‚ the activity of these enzymes were tested at different temperature and times and iodine was used as indicator of presence of starch. During the experiment we observed that bacterial amylase had faster enzymatic activity than fungal amylase; bacterial amylase achieved 100% hydrolysis at 40°c and 60°c at 2 minutes time and fungal amylase achieved partial hydrolysis at 60°c at 4 minutes time. With all of this we can say that the optimal temperature for fungal and bacterial

CASE 1-2 : McDonald’s expands globally while adjusting its local recipe Discussion Questions : 1-18. The key elements in McDonald’s global marketing strategy are based on the concept of this quick-service restaurant which is delivering three things to customers: inexpensive foo‚ quick-service and clean and familiar environment. Memorable advertising and intensive promotion efforts are two important tools that made McDonald’s one of the world’s most valuable brands. For instance “I’m loving it”

Laboratory #1 Introduction to Laboratory Techniques Sean Pence Jackie Butler September 6‚ 2012 September 13‚ 2012 Abstract: This lab contains four different experiments. All four experiments focus on proper laboratory techniques. The reasoning behind this lab was to become familiar with lab equipment‚ the proper usage of lab equipment‚ and how to correctly take data and notes. The first experiment of this lab was to determine the volume of water in various types of equipment. The second experiment was to

Unit 1 Lab 1 Data on Fixed Line vs. Cellular Debate June 16‚ 2014 Debate the Pros and Cons to having a purely cellular network vs. having a purely fixed line network Pro ’s: Cost: Most wireline phone companies charge more than what you ’d pay for most alternatives‚ and some are taxed more as well. There are some locations where getting new wired phoneservice is prohibitively expensive or even impossible. Long Distance and extra features like Call Waiting are normally included with alternative

Throughout this lab‚ diffusion and osmosis has been seen and tested through experiment. In part A of the lab‚ diffusion was demonstrated with two solids and an agar gel petri dish. One crystal of potassium permanganate and one crystal of methylene blue were placed on either side of an agar gel petri dish. The purpose of this experiment was to determine which of the crystals would diffuse across the gel more. So the question is‚ which solid would have a higher rate of diffusion through the agar‚ methylene

______________________________ Week 1 Lab Goals: 1. Choose your lab group. 2. Learn about lab safety. **IMPORTANT – All students are expected to wear a lab coat and goggles in lab at ALL times. As well‚ you are not permitted to wear shorts or open-toed shoes. If you are not dressed appropriately for lab‚ your TA will dismiss you. You are permitted to return to lab with proper attire and equipment‚ but the rules for lateness will apply (see the syllabus). If you do not return to lab with proper attire and

EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT CONCENTRATION OF GLUCOSE ON POTATO STRIPS INTRODUCTION: Molecules of liquid and gas are constantly in motion‚ they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move‚ they tend to spread out moving from areas with many molecules to areas with fewer molecules . This process of spreading out is called Diffusion‚ for example smell of cooking travelling around the house from the kitchen
