- As habitats change, populations of northern pine trees that were once separated can now exchange pollen. This exchange of genes between populations is allowing the previously isolated gene pools to mix. The mechanism of evolution is gene flow. - A sudden volcanic eruption kills many members of a population of elk. By chance, the individuals that remain do not have the same mix of genes as the original population. The mechanism of evolution is genetic drift. - Although millions of prairie chickens once roamed the Midwest, their numbers dwindled to only 50 individuals in the 1990s. These few individuals have since produced a larger population. The genetic variation among the current population is quite low. The mechanism of evolution is genetic bottleneck. - Insecticide resistance among mosquitos is spreading around the world after mutations that originate in one population are spread to other populations through matings. The mechanism of evolution is gene flow. - Researchers discovered that female gray tree frogs prefer to mate with males who sound the longest mating calls. The mechanism of evolution is sexual selection. - Tristan da Cunha is a remote island in the Atlantic Ocean. In 1814, 15 people formed a colony there, one of whom carried a rare gene for blindness. The frequency of this gene is now 10 times higher on the island than on the mainland from which the settlers arrived. The mechanism of evolution is founder effect.

3. Assume that the money demand function is (M/P)d = 2,200 – 200r, where r is the interest rate in percent. The money supply M is 2,000 and the price level P is 2. If the price level is fixed and the Fed wants to fix the interest rate at 7 percent, it should set the money supply at: A) 2,000. B) 1,800. C) 1,600. D) 1,400. 4. In the Keynesian cross model, the distance between the 45 degree line and the planned expenditures line indicates the amount of the: A) liquidity preference. B) the government-purchases multiplier. C) unplanned inventory investment. D) real money balances. 5. If C = 200 + 0.75(Y – T) and I = 200 – 25r, then the formula for the IS curve is: A) Y = 400 – 0.75T – 25r + G. B) Y = 1,600 – 3T – 100r + 4G. C) Y = 400 + 0.75T – 25r – G. D) Y = 1,600 + 3T – 100r – 4G. 6. The intersection of the IS and LM curves determines the values of: A) r, Y, and P, given G, T, and M. B) r, Y, and M, given G, T, and P. C) r and Y, given G, T, M, and P. D) p and Y, given G, T, and M. 7. If the LM curve is vertical and government spending rises by G, in the IS-LM analysis, then equilibrium income rises by: A) G/(1 – MPC). B) more than zero but less than G/(1 – MPC). C) G. D) zero.
