THE EFFECT OF HYDROGEN BONDING ON RESISTING FLOW Design Investigating a factor affecting the viscosity of a mixture of liquid Research Question The effect of hydrogen bonding on resisting flow of five different liquids Background Theory Viscosity is the resistance of a fluid to flow‚ either within itself‚ or to moving past an objects moving through it. A liquid with high viscosity is thick and flows slowly. A liquid with a low viscosity is thin and flows quickly. Different liquids

Essay about Obesity Obesity results from chronic energy intake that exceeds energy expenditure and is characterized by "excessive" body fat. The precise assessment of an individual’s body fat is an expensive and complicated procedure. Instead‚ body mass index (BMI)‚ though somewhat controversial‚ is used commonly because it is easy to assess and correlates highly with body fat. BMI is calculated by taking an individual’s weight in kilograms and dividing it by that individual’s height in meters squared

In the process of cellular respiration‚ there are three main parts; Glycolysis‚ Krebs Cycle‚ and Electron Transport Chain. All three of these processes form together to make cellular respiration happen‚ and that gives our bodies energy to do the work that we need to perform every single day. Without cellular respiration‚ our bodies would not have enough energy to perform everyday tasks‚ let alone live and survive. The first process‚ glycolysis‚ starts with a few molecules of glucose. There are

The client’s food log was extreme. She tracked every bite she ate and calculated the calories in each item. In the log‚ she described every workout and the calories she had burned. She was working out several times a day. The most extreme thing about her food log was that it included almost nothing but sugar: pastries‚ chocolate‚ malted milk Whoppers‚ fat-free muffins. All day. Her health issues were fairly severe and varied: irregular menstrual cycles‚ endometriosis‚ breast engorgement and tenderness

a) The ATP molecule is composed of three components. At the centre is a sugar molecule‚ ribose (the same sugar that forms the basis of RNA). Attached to one side of this is a base (a group consisting of linked rings of carbon and nitrogen atoms); in this case the base is adenine. The other side of the sugar is attached to a string of three bonded phosphate groups. These phosphates are the key to the activity of ATP. Especially‚ the bond between the last phosphate and second to last phosphate is

The Documentary ‘King Corn’ is an intersting and entertaining account that examines the impact of the corn industry on food production in America. The film follows Curtis Ellis and Ian Cheney‚ two recent university graduates who set out to study the overwhelming influence that industrial corn has on the varieties of foods that America consumes each year. The concept of the film is introduced when Curt and Ian have samples of their hair examined‚ and are surprised to find out that the large amounts

Respiration is the process by which energy is released energy from glucose in the presence of Oxygen‚ forming carbon dioxide and water as waste products. Glucose releases energy in a series of reactions that take place inside components of the cell. The stages are briefly explained below as were briefly explained in part A‚ the process then goes through‚ glycolosis‚ link reaction and then the Krebs cycle. The volume of CO2 that is produced in the Krebs cycle is important as this is the dependant
