Eating junk food can have a significant impact on one’s health. Though many people enjoy eating junk food and think it tastes great‚ the health consequences can be serious‚ and can range from everything to low energy levels to weight gain and illness. The term "junk food" encompasses a fairly broad category of food‚ but it typically refers to foods that are relatively high in caloric content‚ but low in nutritional value. Junk food is often high in sugar‚ salt‚ white flour‚ and fat‚ particularly saturated

Junk Food Sucks Eating junk food can have a significant impact on one’s health. Though many people enjoy eating junk food and think it tastes great. The term "junk food" typically refers to foods that are relatively high in caloric content‚ but low in nutritional value. Junk food is often high in sugar‚ salt‚ white flour‚ and fat. A few examples of foods often considered to be junk food include fast food‚ sweets such as ice cream‚ candy‚ donuts‚ and prepackaged treats

The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang‚ osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang‚ 1997). Osmosis is able to maintain osmotic pressure and regulate a cell’s volume. In a hypotonic () or hypertonic () environment

Title: Experiment 28: Nitration of Methyl Benzoate Objective: The students will learn to nitrate methyl benzoate through electrophilic aromatic substitution reaction. They will learn the importance of regiochemistry in chemical reactions. They might experience disubstitution through a high temperature. Reactions: Observation: The crystals started to form when added 2 g of crushed ice. The addition of hot methanol dissociated the crystals. The crystals reappeared when cooled down in

MEASURING pH Date of Lab: 02/09/13 Date Report submitted: 02/26/13 Purpose of the experiment By doing this experiment‚ we were trying to learn how to measure a pH with a pH meter to determine whether a solution is weakly‚ moderately or strongly acidic or basic; but also to compare the different data founded to see how the addition of certain liquid to a solution may affect the pH of the initial solution. Materials We used: * Tap water‚ distilled water‚ Soda and milk as the main

KNES 470 Dr Rubin 4-18-12 Sodium Bicarbonate and Boxing Performance Boxing is a sport which relies on anaerobic power since it contains short-duration and high intensity work. A typical boxing match today consists of 3 minute rounds with a 1 minute seated recovery rest. When an athlete performs exercise at maximal level for more than 30 seconds‚ most of the energy comes from anaerobic glycolysis. During this process‚ lactic acid is produced which causes a decrease in pH levels within the muscle

INTRODUCTION: The nitration of methyl benzoate is an example of an electrophilic aromatic substation reaction. In the experiment the electrophile was the nitronium ion and the aromatic compound was methyl benzoate and with addition of nitrating solution Methyl 3-nitrobenzoate was the product.

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded
