Although GDP is a reasonably good measure of a nation's output, it does not necessarily include all transactions and production for that nation. Which of the following scenarios are either not accounted for or measured inaccurately by either the income or the expenditure methods of calculating GDP for the United States? Check all that apply. Federal government paychecks to soldiers The value of babysitting services, when the babysitter is paid in cash and the transaction isn't reported to the government The variety of goods available to consumers The costs of overfishing and other overly intensive uses of resources When a U. S. company purchases and imports electronic parts from China to use to produce MP3 players within the United States, this purchase increases the component of GDP while also net exports by the same amount. Therefore, the purchase of electronic parts from China causes in US GDP.

The following scenarios from the listed are either not accounted for or measured inaccurately by either the income or the expenditure methods of calculating GDP for the United States. They include;

1) The value of babysitting services, when the babysitter is paid in cash and the transaction isn't reported to the government.

2) The variety of goods available to consumers

3) The costs of overfishing and other overly intensive uses of resources.

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.'
