An appliance store sells 500 units of a particular type of dishwasher each year. The demand for this product is essentially constant throughout the year. The store orders its products from a regional supplier, and it typically takes two weeks for the dishwashers to arrive after an order has been placed. Each time an order is placed, an ordering cost of $1,000 is incurred. Each dishwasher costs the hardware store $300 and retails for $550. The store's annual cost of capital is estimated to be 7% per year. Using the economic order quantity (EOQ) formula, determine the optimal order quantity

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.'
