Suppose that, for every 1-percentage-point decline of the discount rate, commercial banks collectively borrow an additional $2 billion from Federal Reserve Banks. Also assume that the reserve ratio is 20 percent. If the Fed increases the discount rate from 4.0 percent to 4.25 percent, bank reserves will: Group of answer choices

A. increase by $0.5 billion and the money supply will increase by $2.5 billion.
B. decline by $0.5 billion and the money supply will decline by $2.5 billion.
C. increase by $0.75 billion and the money supply will increase by $3.75 billion.
D. increase by $1 billion and the money supply will increase by $5 billion.

i think you have to let the moderators that you want your old account to be activated.

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.'

i would say their habit of breaking down.
