Use 2015 Form 990 and the 2016 annual report for Feeding America. Although the Form 990 indicates it is for 2015, it is actually for the period July 1, 2015, to June 30, 2016, the same time period as the 2016 annual report.

Required

Compute the following performance measures using the Form 990. Using the annual financial statements, calculate the following performance measures.

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 is true.  i do believe this is the answer because of the amount of wrecks people get into each year.  if you double this with avoiding those so said wrecks, that would make you a "skilled" driver.
