Chapter 3: Problem 2: Appalachian Coal Mining believes that it can increase labor productivity and‚ there- fore‚ net revenue by reducing air pollution in its mines. It estimates that the marginalcost function for reducing pollution by installing additional capital equipment is MC 40P where P represents a reduction of one unit of pollution in the mines. It also feels that for every unit of pollution reduction the marginal increase in revenue (MR) isMR 1‚000 10P How much pollution reduction should

Introduction Methionine and cysteine are both sulphur containing amino acids. Most proteins will contain one‚ or both of them at some point in the polypeptide chain. As such‚ many amino acids contain sulphur in some form‚ which is required in small amounts in the mammalian diet. Methionine has a thioether side chain‚ and cysteine’s contains a thiol group. These side chains exist as free thiols inside the cell‚ and are oxidised causing them to pair up and form disulphide bonds in an extracellular

strawberry is because we’d be able to extract more DNA. Ripe strawberries make enzymes which help break down the cell walls making it easier to extract the DNA. We will be using a solution called lysis buffer which is made out of water‚ detergent‚ and salt. The detergent is used to help dissolve the lipid bilayer of the cell membranes. The salt is used to help remove the proteins from the DNA and to keep the proteins in the extract layer so that they aren’t mixed in with the DNA extract. Cold alcohol

ANALYSIS OF VARIANCE? WHAT NULL HYPOTHESIS ISTESTED BY ANOVA? ANALYSIS OF VARIANCE IS A STATISTICAL METHOD USED TO TEST DIFFERENCES BETWEEN TWO OR MORE MEANS. IT IS USED TO TEST GENERAL RATHER THAN SPECIFIC DIFFERENCES AMONG MEANS. THUS THE NULL HYPOTHESIS IS CALLED AN OMNIBUS NULL HYPOTHESIS IT MEANS THAT AT LEAST ONE POPULATION MEAN IS DIFFERENT FROM AT LEASTONE OTHER MEAN.
