The Cold War started with building tensions between the US and the USSR during World War II. As Stalin began to annex more countries and spread communism throughout Eastern Europe, the US began to feel threatened and feared that they would start a war amongst the capitalist nations. The US started an attempt to limit the spread of communism and protect capitalism, which led to a series of passive aggressive and indirectly hostile exchanges between the two nations.

The beginning of the end of the cold war, the Berlin Wall came down. The USSR began to collapse the following year, in 1990.

In business, outsourcing is an agreement in which one company contracts its own internal activity to different company. It involves the contracting out of a business process (e.g. payroll processing, claims processing) and operational, and/or non-core functions (e.g. manufacturing, facility management, call center support) to another party (see also business process outsourcing).

A company moves some of its jobs to another country and employing workers in other countries to save on labor costs best describes the practice of outsourcing.

Mutations are accidents in the copying of DNA. A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. 

Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo. These changes if they are in the germ cell will be passed on to other organisms formed by sexual reproduction or asexual reproduction. An example would be the golden delicious apple. A lost of genetic information due to a mutation resulted in a different color of fruit.

Genetic mutations that cause diseases are not always passed on to offspring. 

Metabolism (from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical transformations within the cells of organisms. The three main purposes of metabolism are the conversion of food/fuel to energy to run cellular processes, the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates, and the elimination of nitrogenous wastes.

In brief, the chemical processes that occur within a living organism in order to maintain life is called metabolism.
