Common allocation bases are a. direct labor dollars, direct labor hours, machine dollars b. direct labor dollars, direct labor hours, direct material dollars c. direct labor dollars, direct labor hours, machine hours d. machine dollars, direct labor dollars, direct labor hours

c.direct labor dollars, direct labor hours, machine hours

Explanation:

The allocation bases are the base through which the overhead cost is allocated on the basis of direct labor in dollars amount, direct labor hours, machine hours, occupied square foot, etc

The base of allocation is the allocation method through which the indirect cost is distributed to the departments like - production department, service department, etc

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.'
