The Wyeth Corporation produces three products, A, B, and C, from a single raw material input. Product A can be sold at the split off point for $40,000, or it can be processed further at a total cost of $15,000 and then sold for $58,000. Joint costs total $60,000 annually. Product A should be: Multiple Choice discontinued because revenues after further processing are less than total joint costs. sold at the split-off point. processed further and then sold. processed further only if its share of the total joint costs is less than the incremental revenues from further processing.

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.'
