DONT ANSWER UNLESS U HAVE TAKEN THE TEST ON EDGE AND KNOW ITS CORRECT
Answer:
B, stage two
Explanation:
Option-B. Stage 2 is the correct answer
Stage 2 is light sleep, which is characterized by a drop in body temperature and a slowing of the heart rate. The body is currently prepared for a lengthy nap. It could last between ten and twenty minutes.
Different Stages of Sleep cycle-Stage 1=There are five phases of sleep: Theta waves predominate in stage 1 sleep in the brain. The sleeper has closed their eyes and is in a very light slumber, however because of how light the sleep is, it is simple to wake them up. In fact, a phenomena known as a hypnic jolt can cause a person to suddenly awaken on occasion.
Stage 2=The person twitches as their muscles start to slowly contract and relax during stage 2 sleep. Heart rate, breathing rhythm, and body temperature all decrease when the body starts to slow down. Theta waves still predominate in the brain, but deeper delta waves start to appear.Stage 2 is light sleep, during which the body temperature declines and the heart rate slows. At this point, the body is preparing for a deep slumber. It may go on for ten to twenty minutes.Eye movement stops during this phase, and brain waves slow down with the exception of brief pulses known as sleep spindles.
Stage 3 and 4=Sleep stages three and four are quite similar. In order to distinguish between the two groups, scientists typically say that fewer than 50% of brain waves occur during stage 3 and more than 50% occur during stage 4. Even now, some researchers are starting to lump these subgroups into a single stage 3 category characterized by delta waves. The sleeper is most profoundly asleep and experiencing the strongest physical and psychological recuperation during these phases of sleep.
Stage 5 or Final stage=The final stage of sleep is called REM sleep, so named because it is frequently accompanied by rapid eye movements. The sleeper's brainwave pattern starts to become significantly more active at this point of sleep. In fact, the alpha or beta wave pattern of an awakened person is very similar to the brain waves of this period. Dreams will be experienced by the person at this stage.
