B1a Fitness and health 1. You should be thinking about the differences between health and fitness‚ concentrating on the causes and prevention of heart disease‚ which is the most common cause of death in the UK. 2. Have ideas on encouraging a healthy lifestyle e.g. ways to reduce the risk of heart disease and high blood pressure e.g. give up smoking‚ avoid eating high levels of salt and avoid eating high levels of saturated fat. 3. Know that the risk of developing heart disease can be increased

pleasant‚ fruit-like odors and are the chemicals responsible for the odors and flavors of many fruits (oranges‚ bananas‚ pineapples) and flowers. In most cases‚ such natural products get their properties from a mixture of organic compounds. In this experiment you will prepare two esters of o-hydroxybenzoic acid‚ more commonly known as salicylic acid. One of the esters‚ acetylsalicylic acid‚ is aspirin‚ the common analgesic. We will synthesize aspirin by mixing salicylic acid with acetic anhydride. The

I am doing an experiment to find out the effect that osmosis has on Water solution and a Sugar solution. Osmosis is a process which water moves from an area of low concentration to an area of high concentration. I am going to record my results to see if osmosis occurs in water solution of sugar solution. Apparatus In this experiment I would need; - 1) 3 test tube 2) A beaker 3) A cork borer 4) A Knife Safety In this experiment safety will not be a

Introduction In this investigation‚ me and my partners performed an experiment to find the different energy contents in food and different amounts of energy released when consumed. Throughout this experiment our procedure was to take different food samples and use a device known as a calorimeter made from a can of aluminum‚ one large paper clips and a string of copper wire to measure the amount of thermal energy released during a reaction. By measuring the temperature difference before and after

Introduction to Biology‚ Lesson 3 Essay Questions: Compare and contrast directional selection and disruptive selection‚ and provide an example of each. Both of these show the distribution of phenotypes. In directional selection‚ the distribution of phenotypes forms a "bell curve." Selection against one of the extreme phenotypes causes the distribution to move in one direction or the other. An example might be plants whose flower color is determined by incomplete dominance: white‚ pink‚ or red

- Quasi Experimental Design: If the researcher lacks control over the assignment of participants to conditions and does not manipulate the causal variable of interest‚ the design is quasi experimental. o Quasi Experiments do not have internal validity because participants are not randomly assigned to conditions and the researcher may have no control over the independent variable. - Basic Confounds in Quasi Experimental Design are : o History o Maturation (Emotional‚ Physical & Psychological)
