FINAL SUMMATIVE PRESENTATIONS This evaluation will involve working in groups of 3 to prepare a written report‚ poster and a demonstration of food preparation of your chosen topic. PART A: WRITTEN REPORT This should give the reader background information on your selected topic. This information will be shared with the class as an ongoing commentary in addition to your demonstration. The report will be typed using proper report format with a title page and subheadings. It should

CELL STRUCTURE CELL THEORY: Structural and functional unit of all living things New cells arise from already existing cells Cells contain information that instructs growth. This information can be passed onto new cells. MICROSCOPES: There are two main types of microscopes: Light and Electron Electron Micrographs- shown in colour LIGHT ELECTRON Uses beam of light Magnification = x1500 Resolution = 200 nm Wide range of specimens can be used Samples are fairly quick + easy to prepare

Experiment 9 : The effect of substrate concentration on enzyme activity Objective To find out the relationship between the substrate concentration and the rate of reaction by determining the number of bubbles produce Hydrogen peroxide (H2O2) is a by-product of biochemical metabolism. An accumulation of hydrogen peroxide can be deadly‚ so it has to be decomposed. One of the decomposing factors is an enzyme called Catalase. Catalase breaks hydrogen peroxide into water and oxygen. The chemical

Properties of Different Bonds An ionic compound forms from a nonmetal and metal element. A covalent compound is formed by two non metal elements. A metallic compound is formed by two metal elements. Metallic compounds have generally high melting points‚ are loose and flexible with their electrons‚ conduct electricity well‚ and have low solubility in water. Ionic compounds are generally crystals‚ have a high melting point‚ and usually have high solubility in water and conduct electricity well when

Question 1 Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength () and frequency () are related according to the equation where is the speed of light (). The energy ( in joules) contained in one quantum of electromagnetic radiation is described by the equation where is Planck’s constant (). Note that frequency has units of inverse seconds ()‚ which are more commonly expressed as hertz (). Part A A microwave oven operates at 2.40 . What is the wavelength

CHEM 3305 - 001 Organic Chemistry 1 Dr Michael Findlater Spring Semester‚ 2013 Stereochemistry • Stereochemistry refers to the three-dimensional structure of a molecule. • As a consequence of stereochemistry‚ apparently minor differences in 3D structure can result in vastly different properties. • We can observe this by considering starch and cellulose‚ which are both composed of the same repeating unit.
