Nuclear energy is created during a fission or fusion, and is typically used to generate electricity. Nuclear power plants use the fission or fusion reaction to create the nuclear energy, which generates heat. This heat the power plants use to transform the heat energy into electricity. Fission is where large nuclei are split into smaller nuclei. Fusion is where the small nuclei are put together to create large nuclei. These two reactions create nuclear energy.
        
             
        
        
        
Answer:
In 1849, Californians sought statehood and, after heated debate in the U.S. Congress arising out of the slavery issue, California entered the Union as a free, nonslavery state by the Compromise of 1850. California became the 31st state on September 9, 1850. ... California situated its first capital in San Jose.
The northern boundary was set along the 42nd parallel. The southern boundary had already determined by the Treaty of Guadalupe-Hidalgo with Mexico. The northeast corner of the state would be the point where the 42nd parallel met the 120th meridian, to include the Sierras.

The correct answer is - A) subsistence farming.
Subsistence farming is the type of farming that is mostly practiced in the less developed countries. In here we have production that is just about enough for the needs of the country (and big portion of the production doesn't even come out on the home market, but you eat what you produce, or trade with someone you know). Also this type of farming is still based on primitive tools and is heavily dependant on the climate, and that makes it very unstable and more often than not people are starving because not enough food has been produced.
