Misconception about the nature of scientific knowledge (nature of science) The definition of scientific knowledge is that it is “accumulated by systematic study and organized by general principles”. Many people think that scientific knowledge is absolute and cannot change‚ but this is not true‚ because science is a process for producing knowledge the process is to make careful observations of phenomena and to invent theories out of those observations. Change in knowledge is necessary‚ because

I. INTRODUCTION A. Significance of Study Information Systems (IS) is a discipline concerned with the strategic‚ managerial and operational activities involved in the gathering‚ processing‚ storing‚ distributing and use of information‚ and its associated technologies‚ in society and organizations. It is a set of organized procedures which‚ when executed‚ provides information to support decision making. By utilizing the information provided it gives the decision makers‚ the managers‚ boss‚ executives

structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;

There are COX enzyme isoforms include COX-1 and COX-2. (Figure 3.8) These enzymes originate from different genes and have distinct tissue-specific expressions and biologic functions. COX-1 is constitutively expressed in most tissues and believed to responsible for the production of prostanoids in homeostasis‚ such as gastric epithelial cytoprotection and renal blood flow maintenance. COX-2 expression is inducibly expressed only at marginal levels under condition in many tissues and is upregulated

Enzyme activity The introduction is a statement of the subject and objectives of the experiment and presents your hypothesis. Relevant background information (appropriately referenced) is given in sufficient detail that a person unfamiliar with the topic can understand the nature of the experiment. A good introduction is clear and concise. Carbohydrates and proteins should be explained in terms of their structure and major functions in cells. Your intro should end with a brief overview of the amylase

1a.) WHAT IS THE SCIENTIFIC INQUIRY? The Scientific Inquiry is the route by which scientists ask questions‚ develop and carry out investigations‚ make predictions‚ gather evidence and suggest explanations. b.)NAME SOME IDEAS ABOUT THE NATURAL WORLD THAT HAVE CHANGED OVER TIME BECAUSE OF NEW OBSERVATIONS. The idea of the earth being flat and that the earth was the center of the universe was proved inaccurate by one of the world’s greatest scientist: Galileo Galilei. By studying and making observations

The news in the last year has said there has been an increase in the rate of childhood obesity. What has caused this increase in the rate and how can we work to reduce it in the future. My hypothesis for my question is that the cause of obesity rate and how it is caused is that you don’t see too many children who are overweight or obese but can be caused that there are some genetic and hormonal causes towards obesity and overweight children. But it can also be caused by kids just eating too much

Effects of Gender‚ Athleticism‚ and Measurement Position on Vital Capacity of College-aged Students Caleb Campbell Principles of Biology- Laboratory Section A 4/22/2014 Abstract Vital capacity is defined as the amount of air that can be forcibly expelled from the lungs following breathing in as deeply as possible. The purpose of this study was to see if position of measurement‚ gender‚ and athleticism affected vital capacity. This experiment was conducted on 46 college-aged students using
