1KU ii. What is an enzyme?1KU iii. Give another example of an enzyme and its use.1PS 3. In the manufacture of malt vinegar‚ starch reacts with water to produceglucose. Glucose is converted to carbon dioxide and ethanol using an enzyme. Ethanol is oxidised‚ by bacteria‚ producing malt vinegar.

Lesson: This should be presented as a chemistry experiment. Ask the kids what a chemical reaction is? Did they know they can make gasses out of liquids or solids? What happens if they put things like baking soda and vinegar together? If they don’t know‚ tell them the two create a gas when combined. What’s gonna happen if you combine

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

genus Prunus‚ and is a fleshy drupe (stone fruit). It is usually bought in groceries and is used as toppings on ice cream sundaes and cakes. The cherries will act as the main component of the ink. The researchers will also add vinegar and salt to the mixture of the cherries. The vinegar and salt will clarify and deepen the color of the ink as well as preserve the mixture from spoiling. The equipment that will be used by the researchers is within their financial capability and it can be completed within

baking‚ Vinegar can also make the baking soda simulate an eruption due to the acid in the vinegar having a chemical reaction to the sodium hydrogen carbonate (baking soda) making it release CO2 (carbon dioxide). Secondly baking powder has baking soda‚ acid salts and starch. An acid salt is chemicals such as sodium aluminium phosphate and tartaric acid. Rice or corn is commonly used as the starch. For centuries baking powder has been developed so that people who use it do not have to add vinegar (which

write down our hypothesis for what we think the mass/volume would be and so on. On the first day‚ Friday‚ in the lab we took a graduated cylinder and filled it with 250ml of vinegar before pouring it into a beaker with an egg inside of it and covering it with saran wrap to let it sit out for two days. On Monday we drained the vinegar from the beaker‚ leaving the egg in it‚ and measured how much was not soaked into the egg. We recorded the results along with our observations. Then we rinsed off the egg

English Commentary- Snowy Morning‚ by Henry Shukman. “Snowy Morning” is a melancholy piece about the difficulty and inevitability of saying goodbye to a lifetime of images‚ sensations and the beauty of the world around us. Shukman uses images from childhood to create a sense of nostalgia as well as establishing a paradox between the fear of death and dealing with death in a facetious manner. In addition to this Shukman uses semantic fields dealing with the senses in order to create a more involved
