Which of the following is not correct?a. If the inflation rate exceeds the nominal interest rate, then the purchasing power of an interest-earning deposit falls over time. b. If there is deflation, then the purchasing power of an interest-earning deposit rises by more than the nominal interest rate over time. c. The higher the rate of inflation, the smaller the increase in the purchasing power of an interest-earning deposit. d. The purchasing power of an interest-earning deposit can increase or decrease over time, but it cannot stay the same.

The options which is NOT correct is C.

Purchasing power does not increase with inrease in the rate of inflation. There is an inverse relationship between inflation and purchasing power of money.

Explanation:

Inflation refers to the overall increase in prices of goods and services and the erosion of the power of the currency to purchase those goods and services. In otherwords, when inflation happens, one requires more dollar bills to purchase same unit of goods or services.

Deflation is the opposite of inflation. It refers to the decrease in the prices of goods and services and is usually accompained by an increase in the purchasing power of the currency.

Nominal interest rate simply put is the interest payable on a loan without considering processing fees, compounding interest payable and the erosion of the value of such money.

whats the

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.'
