Answer:    Decreased levels of melatonin

Explanation:  Melatonin is a substance that is excreted at night and by which the brain sends signals that one should sleep, that is, a man / woman is feeling sleepy. When melatonin secretion decreases, the alertness increases, as is the case with Colby. Melatonin levels decrease at the base of the brain signal regardless of whether or not Colby slept enough the previous night. Feeling tired will induce some other receptors and consequent signals from the brain, but a natural decrease in melatonin throughout the day occurs normally.

Describe the cultural revolution and its impact?
Nezavi [6.7K]

Answer:

:>

Explanation:

The Cultural Revolution was launched in China in 1966 by Communist leader Mao Zedong in order to reassert his authority over the Chinese government. Believing that current Communist leaders were taking the party, and China itself, in the wrong direction, Mao called on the nation’s youth to purge the “impure” elements of Chinese society and revive the revolutionary spirit that had led to victory in the civil war 20 years earlier and the formation of the People’s Republic of China. The Cultural Revolution continued in various phases until Mao’s death in 1976, and its tormented and violent legacy would resonate in Chinese politics and society for decades to come.

In the 1960s, Chinese Communist Party leader Mao Zedong came to feel that the current party leadership in China, as in the Soviet Union, was moving too far in a revisionist direction, with an emphasis on expertise rather than on ideological purity. Mao’s own position in government had weakened after the failure of his “Great Leap Forward” (1958-60) and the economic crisis that followed. Chairman Mao Zedong gathered a group of radicals, including his wife Jiang Qing and defense minister Lin Biao, to help him attack current party leadership and reassert his authority.
