Galaxy technologies corp. manufactures cell phones. during the year, 150,000 phones were manufactured. materials and labor standards for producing the phones are as follows:
direct materials (2 pieces of plastic material @ $3.25) - $6.50
direct labor (2 hours @ $10) - 20.00
galaxy technologies corp. purchased and used 500,000 pieces of plastic material at $2.50 each, and its actual labor hours were 340,000 hours at a wage rate of $10.50. what is the materials price variance?

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.'
