Describe the challenges and opportunities of globalization in a ""flattened"" world.

Answer and explanation:

American journalist and writer Thomas Friedman (born in 1953) in his book "The World Is Flat: A Brief History of the Twenty-First Century" (2005) uses the term "flattening" to describe the phenomena by which the world is tearing down barriers thanks to computers and the internet and its impact in the worldwide economy.

Having a flattened world has allowed commerce to spread massively. Buyers and sellers from anywhere on the planet can match their needs on a web page. Besides, job opportunities have increased mostly for developing countries since work is taken to those regions due to cheaper labor costs. But the last situation represents an advantage for workers but a disadvantage at the same time. The labor force in the company's domestic countries is affected by the outsourcing of work.

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.'
