The following graph shows the relationship between the unemployment rate and the inflation rate in a hypothetical economy. Suppose that the economy is in a situation where, because of cost factors (for example, a spike in energy prices), inflation will be at least 3.00 percent, and the number of unskilled workers and people "between jobs" (sometimes called "frictional unemployment") cause the unemployment rate to be at least 3.70 percent. Suppose the economy is currently sitting at 4.35 percent unemployment and 5.50 percent inflation and that the central bank decides to implement a restrictive monetary policy. (Hint: Click anywhere on the curve to view some points that make it up.) INFLATION (Percent) Which of the following are unemployment and inflation possibilities given the monetary policy? Check all that apply. ? 5.00 percent unemployment; 3.00 percent inflation ? 8.00 percent unemployment; 3.00 percent inflation ? 6.00 percent unemployment; 4.00 percent inflation ? 3.80 percent unemployment; 7.50 percent inflation Now suppose that oil prices increase substantially and that hundreds of training centers for unskilled workers close down. Figure (1) Figure (2) If curve AB is the original curve and curve CD is the new curve, then the figure that best reflects the central bank's new trade-off position is: ? Figure 1 ? Figure 2

1. Carefully study the light microscope image of cells from an onion root tip, provided below. 2. Count the total number of cells in the field of view, and then count the number of cells in each phase of mitosis. Calculate the percentage of cells in each phase. 3. The average time it takes for an onion root tip cell to complete the cell cycle is 24 hours (1,440 minutes). Calculate the time in minutes that cells spend in each phase. (Multiply percentage of cells in a given phase by 1440 - e.g., if 2%, then (0.02) x 1440 = ~29 minutes.)

(a) In a typical water-cooling tower, warm water flows countercurrent to an air stream. The warm water enters the top of a packed tower and cascades down through the packing, leaving at the bottom. Air enters at the bottom of the tower and flow upward through the descending water. Briefly explain why usually adiabatic mass transfer and constant water flow can be assumed in calculation of tower size. (5 Marks) (b) A typical countercurrent water-cooling tower is to be designed for to cool water from 46.1 to 29.4 $^\circ$C. Air enters at the bottom of the tower at 23.9 $^\circ$C (with a wet bulb temperature of 21.1 $^\circ$C) and flow upward through the descending water. Estimate the tower height needed if 1.5 times the minimum air rate is used. The height of gas enthalpy transfer unit is 0.5 m. (20 Marks) The enthalpies of saturated air-water vapor mixtures are shown in Table 1. State clearly your assumptions.
