If the transactions velocity of money remains constant while the quantity of money doubles, the: price of the average transaction multiplied by the number of transactions must double. price of the average transaction multiplied by the number of transactions must remain constant. price of the average transaction must double. number of transactions must remain constant.

price of the average transaction multiplied by the number of transactions must double

Explanation:

This follows the principle of the Quantity theory of money. Thus according to this theory when the rate of change of the transactions of money in an economy has remain constant or unchanged, while the supply of increases twice as before it will result in a situation where;

the price of the average transaction multiplied by the number of transactions must double because of increase supply of money.

This simply implies that the more money in circulation, the more the price of goods and services in an economy.

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.'

the answer choices are:
