Answer:
B
Explanation:
B is the answer because the magnetic field of the earth attracts sun Ray's
Answer:
ydropower, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy
Explanation:
In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity. Transformers are then used to convert the alternating voltage suitable for the generators to a higher voltage suitable for long-distance transmission. The structure that houses the turbines and generators, and into which the pipes or penstocks feed, is called the powerhouse.
Answer:
Behavioral Genetics
Explanation:
The subject of Behavioral Genetics is usually defined as the study of genetic and environmental effects that occurs in the behaviors. This is important because by studying these effects of genetic influences, a large number of information can be obtained regarding how the environment controls the behavioral influence. This subject is commonly known as the Psycho-genetics. In simple words, this studies the interaction between the environment and the heredity, thereby affecting the behavior.
