Pepsodent launched a new product that could whiten teeth, fight decay, and maintain fresh breath. Observing that Pepsodent did not focus on the dental sensitivity aspect, Colgate introduced a toothpaste which did all of the above and also protected sensitive teeth. This is an example of a(n) attack. A. bypass B. encirclement C. flank D. frontal

C. flank

Explanation:

A flank attack refers to an act by a product company whereby it attacks the weak links in the products of it's major competitor, particularly a leader.

In such scenarios, the company observes the limitations of the competitor's products and then embodies them in it's own new similar product. In a flank attack, the two companies deal in similar products which can be substituted for one another.

In the given case, Colgate came out with a similar product with improved aspect which it's major competitor's product overlooked i.e dental sensitivity aspect. This represents a case of flank attack.

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.'
