You are the only pharmacist in a small town; the closest drugstore is 50 miles away. the population in your town consists of young farmers and older retired families. you have noticed that the young farmers are less sensitive to price changes than the retired population. specifically, you have found that the working population has an own price elasticity of demand of -2 and the retired farmers have an own price elasticity of -4. how can you use this information to your advantage?

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.'
