Appraisal costs are costs incurred . A. after the company delivers poorminus quality goods or services to customers and then has to make things right with the customer B. to detect poor minus quality materials, goods, or services C. when the company corrects poorminusquality goods or services before delivery to customers D. to avoid poorminusquality goods or services

Correct answer is option B

Appraisal costs are costs incurred to detect poor minus quality materials, goods, or services

Explanation:

Lets analyze each given option:

A. after the company delivers poor minus quality goods or services to customers and then has to make things right with the customer:

This case corresponds to external failure costs, the costs incurred after the poor quality goods or services are delivered to customers to make things right with the customers.

B. to detect poor minus quality materials, goods, or services:

This case corresponds to appraisal costs, the cost incurred to detect the poor quality goods or services.

C. when the company corrects poor minus quality goods or services before delivery to customers:

This case corresponds to internal failure costs, the costs incurred due to correction before the poor quality goods or services are delivered to customers.

D. to avoid poor minus quality goods or services:

This case corresponds to prevention costs, the costs incurred to avoid poor quality goods or services.

Therefore, the correct answer is option B.

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.'
