A farmer grows wheat and sells it to the miller for $84. The miller turns the wheat into flour and sells it to the baker for $109. The baker turns the flour into bread and sells it to consumers for $189.What is the value added by the baker

Value added = $80

Explanation:

Use the below formula to find the value added by the baker:

Baker buys the flour at the cost of = $109

Baker sells it to the cosmumer and receives = $189

The value added can be calculated by subtracting the cost from the receipts.

Value added  =Receipts from the sale - Cost

Value = 189 - 109

Value added = $80

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; someone must cover the cost associated with the provision of scarce goods in both sectors;
