Twelve years after Starfire's appearance, a similar coffee-shop chain, Reindeer Brews, entered the marketplace. Reindeer charges $3 for a mug of hot cocoa and a similar community experience. How would you characterize this scenario

Price competition in a monopolistically competitive market

Explanation:

The Monopolistic rivalry is an industry state with several firms that are closely linked to each other but offer distinct goods. Therefore, this sector has unlimited entry and exit

Here the company offers the same service but there are totally different in terms of design, service, quality, etc

Hence, the correct option is c

answer; ( prices are sticky);

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.'
