Experiment 9: Growth curve of Serratia marcescens Abstract Bacteria grows by binary fission. The aim of this experiment is to follow the growth of Serratia marcescens in nutrient broth at 37oCby recording the changes in turbidity (cloudiness) by measuring the absorbance of visible light (600 nm) and also to prove that there is an increase in the cell number and not just in mass during the growth. In the experiment we measure the full growth curve of Serratia marcescens by measuring the absorbance

of the yield curve. In your answer also discuss the uses of the yield curve in financial markets‚ why strips are used in the construction of yield curves and why investors would want to invest in zero coupon bonds or strips. The yield curve is a graph that plots the yields of similar-quality bonds against their maturities‚ ranging from shortest to longest. The relationship between yield and maturity is referred to as the term structure of interest rates. The Treasury yield curve is the base or

that supply is fixed then at any given quantity of money (M1) there will be a corresponding demand that varies inversely to the price level‚ i.e. a downward sloping demand curve and there will be an equilibrium price level that ‘clears the market’‚ i.e. demand equals supply. If the quantity of money is increased (M2) the demand curve will shift to the right‚ i.e. at the same price level demand will increase but‚ again‚ supply is fixed. A new equilibrium will be established at the same level of output
