a. How must Rebecce treat the income and expenses of the operation if the dog breeding business is held to be a hobby? b. How would your answer differ if the operation were held to be a business?

answer; ///(d) stand out from all of the others;

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.'

answer; i believe the answer is 40,600,000;
