A stock dividend was declared and distributed which increased common stock $500,000 and paid-in capital $220,000. A cash dividend was declared and paid. The amount of the cash dividend was:

a. $496,000.
b. $556,000.
c. $776,000.
d. $1,276,000.

a

explanation:

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.'

c is the correct answer.
