In its first month of operations, Coronado Company made three purchases of merchandise in the following sequence: (1) 320 units at $ 8, (2) 480 units at $ 9, and (3) 240 units at $ 10. Assuming there are 400 units on hand, compute the cost of the ending inventory under the (a) FIFO method and (b) LIFO method. Coronado uses a periodic inventory system. FIFO LIFO Cost of the ending inventory $ enter a dollar amount $ enter a dollar amount

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.'
