The major breakthrough in the study of dreams came in 1953 when researchers Eugene Aserinsky and Nathaniel Kleitman studied and discovered what happens when a person falls asleep.They found that the body enters into a psycho-physiological state in intervals of 90 minute cycles during sleep. This physiological state consists of heightened brain activity, Rapid Eye Movement (REM), increased breathing, a temporary paralysis of the body and genital engorgement. Through experiments, they confirmed that these physiological observations were the result of the person being in the dream state.
Answer:
the answer would be sorting?
A decrease or increase of a certain population can affect the food chain of an ecosystem
Lets say bugs start dying at a rapid rate in an swamp ecosystem
The frog population would then decrease because they have no bugs to eat
The frog’s predators would then decrease because of the number of frogs to eat are decreasing.
So on and so forth.
Hope this helps!
Answer:
The Greeks joined clinical and clinical life structures hypothesis from the Egyptians, which, in this sense, assumed a vital part in preparing for the improvement of the anatomical sciences (Loukas et al., 2011; Standring, 2006). Galen (129–199 AD) and Aristotle are typically viewed as the dads of life structures (Russel, 1916; Singer, 2005; Leroi, 2014). However, Galen's human life systems were frequently off-base, since he never dismembered people, in any event not to the public information. The way of life of human analyzation grew essentially in the Christian West, rather than the Greco‐Roman culture of the dead body, in which the human body was viewed as debased (Park, 2006). Indeed, Galen based his depictions of human life structures on analyzations of creatures, for example, sheep, bulls, pigs, canines, bears, and especially the "Barbary gorilla," an Old World monkey (Macaca Sylvanus) that has a minimal tail and subsequently cursorily appears to be a primate in this regard (Singer, 2005, 2016; Cole, 1975). Since the life systems of this monkey are altogether different from that of people, especially concerning delicate tissues, for example, muscles (Diogo and Wood, 2012), verifiable blunders had large amounts of Galen's depictions of human life structures. For example, he didn't depict the two most curious muscles of the human forelimb, the flexor pollicis longus, and extensor pollicis brevis, as unmistakable muscles (more models given in Supporting Information Table 1). Also, aside from such exact depictions of macaques that are mistaken for people, he incorrectly portrayed highlights that are comparative in people and macaques, adding to additional blunders about human life structures. For instance, he didn't perceive the extensor carpi radialis brevis and longus as discrete muscles (Supporting Information Table 1).
