When Oliver's Oil Company bills its customers, it has them send their payments to an address that is just for receiving payments, instead of directly to the company's mailing address. Although this system costs Oliver's Oil Company a lot of money, it is worth it because the company receives thousands of checks from customers each business day. What system is this company using to receive its payments

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.'
