Answers

Answer 1

Answer:

B, stage two

Explanation:

Answer 2

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.

When white-nationalist group Citizens for Constitutional Freedom occupied the Malheur National Wildlife Refuge in 2016, they expected support from the public in terms of both praise and material support. They were surprised to receive neither; most people disagreed with their politics, philosophy and actions. This is an example of:_________

a. Base rate information.
b. False consensus effect.
c. Political pedagogy.
c. Consensus.

Answers

Answer:

The right response will be Option b (False consensus effect).

Explanation:

The interpretation of the False Consensus Effect here is that whenever an individual thinks and feels that perhaps the amount of people expressing their interests, despises, perspectives and views would be dependent on their assessment or reasoning mechanism and therefore these individuals presume that perhaps the approach they assess things is equal to other individuals. The concept is considered as a false consensus effect since whenever it applies to certain views of other individuals, the views and reasoning described above emerges across as 'false agreement'.

Other options were never connected to the situation in question. So, the solution here is just the right one.

I WILL GIVE BRAINLIEST AND 100 points!! Imagine that you are a representative attending the secession debate in Georgia in 1861. In two paragraphs, explain whether or not Georgia should secede from the Union. Explain your argument using reasons and evidence. Remember, you are trying to convince others to share your point of view.

Answers

Answer:

The state of Georgia must recognize the fact that in the past we agreed to be part of a great Union. Although the many differences caused by the issue of slavery, Georgia must show loyalty to the Union because divided, the United States will fail as a nation, and there is no sense to confront Americans against each other if we are one nation.  It would be to ask siblings in a family to fight each other.

The United States is greater than its differences. That is why we have the US Congress and the law, to pacifically resolve our issues. Furthermore, the economic consequences that secession would bring could really compromise the stability that we want for our people, not even thinking that a division could take us to a Civil War that nobody wants.

describe four different types of physical processes that create specific physical characteristics​

Answers

Answer:

1. Tectonic movement

2. Erosion

3. Volcanic eruptions

4. Glaciation

Explanation:

✔️ Tectonic movement: This describes the movements of the earth lithosphere - solid rock over a geologic time. Seismic activities (like earthquakes) is most associated with tectonic. When the tectonic plates move, their jagged edges actually slip out and then it causes earthquake.

✔️ Volcanic eruptions: These are explosive or effusive eruption of molten magma which comes from the earth's mantle and forms on the earth surface as lava. When the eruptions occur, a combination of silica and dissolved gas are formed which determine the type of eruption and shape of volcano.

✔️ Erosion: This is the process whereby rock, sediment and soil are carried away by agents of erosion. This physical process changes the landform, loss of soil and the damage of ecosystem.

✔️ Glaciation: Glacial actions have shaped much of the landscape in the arctic and sub-artic regions. Glaciers are usually eroded through the process of plucking and abrasion. During the plucking process, glacier flows over bedrock and softens the blocks of rock that were brought into the ice.

A person who is typically deeply asleep is displaying which pattern of brain waves?
A. theta waves
B.beta waves
C. delta waves
D. alpha waves

DONT ANSWER UNLESS U HAVE TAKEN THE TEST ON EDGE AND KNOW THE CORRECT ANSWER

Answers

Answer:

I think the answer is Delta waves

Explanation:

Period N3 is characterized by a predominance of the slow delta waves, which only happen at the deepest stage of sleep. The slowest brain waves, called delta waves, have a frequency of 0.5.

In stage three of sleep, what happens?

It is more challenging to rouse someone up when they are in stage 3 sleep, commonly known as profound slumber. In N3 sleep, when the body relaxes even more, muscle tone, pulse, and respiratory rate all decrease. The delta wave pattern of brain activity throughout this time is recognizably consistent.

What phase of sleep are delta waves more prevalent in?

Stage IV sleep, the deepest stage of sleep, is characterized by delta waves, the distinctive slow waves that give this stage of sleep its name. These waves have a low frequency (1-4 Hz), high amplitude, and are the major EEG activity in this stage.
