Recently, a suburban chicago won powerball, a multistate lottery game. the game had rolled over for several weeks, so a hige jackpot was at stake. ticket buyers had the choice between a single ump sum of $104 million or a total of $198 million paid out over 25 years (or $7.92 million per year and the payment is made immediately) should they win the game. the winning couple opted for the lump sum. at what interest rate will those two payment options be equivalent?

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.'
