The economy of Elmendyn contains 900 $1 bills. If people hold all money as currency, the quantity of money is $ . If people hold all money as demand deposits and banks maintain 100 percent reserves, the quantity of money is $ . If people hold equal amounts of currency and demand deposits and banks maintain 100 percent reserves, the quantity of money is $ . If people hold all money as demand deposits and banks maintain a reserve ratio of 12.5 percent, the quantity of money is $ . If people hold equal amounts of currency and demand deposits and banks maintain a reserve ratio of 12.5 percent, the quantity of money is $ .

a)    900 dollar as all is M0

b)    900 as the deposit have no multiplier effect

c)    900 as there is no multiplier effect

d) 7,200 taking into consideration the multipler effect from the bank deposit.

e) 4,050 considering the deposit multiplier effect

Explanation:

a; b ; c ) as there is no multiplier effect the quantity of money matches the nominal currency.

d)

M0 (currency and coins) 0

M1 900 / 0.125 =  7,200

Total 4,050

answer; ///(c) the way a government controls the supply,availability,and value of money;

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
