Helen inherited some money from her grandmother. She decided to open a coffee shop. She explored the main market area near her house to scope out the competition. The competitors were all famous branded coffee houses. They heavily advertised their coffee and had a lot of brand awareness among the customers. They sold their coffee at a low price, because they could divide the cost of operations over a large number of sales. There was an area near a business center that seemed distant from these branded coffee houses. She decided to rent this location for her shop. She realized that she would also need to serve coffee that at least equalled the standards of the branded coffee houses.

Helen decided to rent her shop in this location.

Explanation:

Helen choose to rent her shop in the location where there are many competitors. The competitors are well established branded coffee houses who serve coffee to their customers at very low price. In this situation customers will not move to any new coffee house. So Helen decided differentiating her coffee shop from other coffee houses and she decided to open a coffee shop where there are less or no competitors available.

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.'
