The actual price for a product was $58 per unit, while the planned price was $54 per unit. The volume increased by 3,170 to 57,060 total units. Determine the (a) quantity factor and (b) the price factor for sales

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.'

answerobservation;

what is the actual question i have no idea how to answer this w/o a question
