MODULE 1: THE CHEMICAL EARTH 3.1.1: Elements in Earth are present mostly as compounds because of interactions at the atomic level * Identify that matter is made of particles that are continuously moving and interacting Matter: anything that has mass and occupies space. Exists in three different states: solid (s)‚ liquid (l) and gas (g) The Particle Theory: “All matter is made up of small‚ indivisible particles called atoms that are continuously moving” | Solid | Liquid | Gas | Particle

However‚ we show that by engineering line defects and using positive substrate impurities one can obtain a suitable effective transport gap at least for analog applications

Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

Escherichia coli Microbiology Lab NAS 185-14L Introduction In this lab experiment we did several test to determine what our unknown bacteria was. To determine this we recorded the results of how the bacteria reacted to different media. Depending on the results of each test we could narrow down the different bacteria to determine what our unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is

Describe the characteristic features of each minerals. Gold- soft‚ lustrous yellow‚ malleable metal. It is one of the transition metals. It is highly sought after precious metal in jewelry Copper- is valued for strength‚ malleability‚ ductility‚ and ability to conduct electricity and heat. It is also non-magnetic‚ resists wear‚ and forms

The purpose of this lab was to observe the spectral lines of different light sources (Iodine‚ hydrogen‚ helium‚ krypton‚ mercury‚ neon‚ and argon) and to find the wavelength‚ frequency‚ and energy of the emissions of vaporized metallic ions. First‚ we took spectroscopes to look at each light source. The iodine light source seemed coral to the naked eye. When observed with a spectroscope‚ it was clear that there were many red spectral lines followed by relatively similar quantities of orange‚ yellow

This dramatic declarative uses a metaphor to show how inhuman‚ or emotionless/detached men and Bounderby can be‚ the ‘metallic laugh’ suggests a certain coldness and robotic nature. The multiple modifiers in ‘great puffed head and forehead’ indicates the intelligence of Mr Bounderby while also suggesting
