been a good idea. I think people saying he his the oldest and cleverest just gets in his head too much. Shift is very cleaver in other parts of the book too. One way he was cleaver was when he tricked everyone into believing Puzzle was Aslan when Shift dressed up Puzzle in lion skin. Shift also was known as old. He had wrinkles‚he was lazy‚ and demanding. He was very demanding when he had

Spinach Blueberries is one of the many cancer preventing foods. Blueberries are full of antioxidants and flavonoids that prevent cell damage from happening. Antioxidants is a substance‚ like Vitamin C or E that counteracts the damaging effects of oxidation in a living organism. A flavonoid is any group of organic compounds that occur as a pigments in fruits and flowers. One thing that antioxidants is neutralize free radicals‚ atoms that contain an odd number of electrons and are highly unstable. The

respiration. ii. Animals then break down sugars and food. 7. Respiration a. Process by which an organism exchanges gases with its environment b. Process → oxygen is abstracted from air‚ transported to cells for the oxidation of organic molecules while CO2 and H2O‚ the products of oxidation‚ are returned to the environment c. Oxygen is used to split glucose apart‚ releasing energy‚ water and carbon dioxide in our cells. 8. Oxygen Cycle a. Step Three i. Carbon dioxide is released by animals and used

environment’s corrosiveness. (b) What possible mechanisms account for their effectiveness? Attachment of inhibitor molecules to the corroding surface so as to interfere with either the oxidation or reduction reaction; and the formation of a very thin and protective coating on the corroding surface. 17.31 (a) Determine whether the oxidation kinetics obey a linear‚ parabolic‚ or logarithmic rate expression. From the first two equations K₁= 0.238 and K₂ = 14.2; while from the second and third equations K₁ = 0.117

Phenol‚ also known as carbolic acid‚ is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (-C6H5) bonded to a hydroxyl group (-OH). It is mildly acidic‚ but requires careful handling due to its propensity to cause chemical burns. Phenol was first extracted from coal tar‚ but today is produced on a large scale (about 7 billion kg/year) from petroleum. It is an important industrial commodity as a

Chem Factsheet September 2002 Number 37 Redox Equilibria I: Standard Electrode Potentials and Cells To succeed with this topic you need to: • be familiar with the concept of equilibrium (Factsheet 09); • be able to assign oxidation numbers to elements (Factsheet 11). After working through this Factsheet you will: • understand the link between cells and oxidising and reducing powers (redox reactions); • have met the Standard Hydrogen Electrode and why it is needed; • know the definition for Standard

presence of oxygen‚ glycolysis is the first stage of cellular respiration. Without oxygen‚ glycolysis allows cells to make small amounts of ATP. This process is called fermentation. Oxidation phospoholyration Oxidative phosphorylation (or OXPHOS in short) is a metabolic pathway that uses energy released by the oxidation of nutrients to produce adenosine triphosphate (ATP). Although the many forms of life on earth use a range of different nutrients‚ almost all aerobic organisms carry out oxidative

photophosphorylation – occurs in photosynthetic cells‚ which contain light-trapping pigments (chlorophyll); light cause chlorophyll to give up electrons. Energy released from the transfer of electrons (oxidation) of chlorophyll thru a system of carrier molecules is used to generate ATP. c) Oxidation – the removal of electrons d) Chemiosmosis – process whereby energy is released when protons moves along a gradient and is used to synthesize ATP; responsible for most of the ATP generated; process
