The following data pertain to operations concerning the product for the last month: actual materials purchased 7,000 meters actual cost of materials purchased $ 124,250 actual materials used in production 6,500 meters actual output 1,420 units what is the materials price variance for the month?

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.'
