You own and operate a bike store. each year, you receive revenue of $200,000 from your bike sales, and it costs you $100,000 to obtain the bikes. in addition, you pay $20,000 for electricity, taxes, and other expenses per year. instead of running the bike store, you could become an accountant and receive a yearly salary of $40,000. a large clothing retail chain wants to expand and offers to rent the store from you for $50,000 per year. how do you explain to your friends that despite making a profit, it is too costly for you to continue running your store?

(a) find your accounting profit.

(b) find your economic profit.

(c) explain your decision.

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.'
