Sheffield Corp. incurred the following costs for 60000 units: Variable costs $360000 Fixed costs 392000 Sheffield has received a special order from a foreign company for 3000 units. There is sufficient capacity to fill the order without jeopardizing regular sales. Filling the order will require spending an additional $4200 for shipping. If Sheffield wants to earn $6000 on the order, what should the unit price be

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.'
