Read the following excerpt from a bigger passage.

from Yawning Together by Dave Munger

• Most yawns last about six seconds.

• While the majority of the 58,000 species of vertebrates yawn, only humans, chimpanzees,
and dogs appear to find them contagious.

• Humans are capable of yawning as young as 11 weeks after conception—before they are
even born!

• Yawns become contagious in humans between the first and second years of life.

• While yawns are commonly associated with boredom or fatigue, your heart rate actually
increases during a yawn—by as much as 30%.

What is the primary purpose of the article?
A) To summarize research on contagious yawning
B) To explain why yawning is healthful for people and animals
C) To describe how human yawning differs from dog yawning
D) To suggest that scientists will never fully understand why people yawn

Answers

Answer 1

Answer:

d

Explanation:

Answer 2

The primary purpose of the article is D. To suggest that scientists will never fully understand why people yawn

What's the article about?

One theory is that yawning helps to increase oxygen levels in the blood. This theory is based on the observation that people yawn more when they are tired or bored, which are times when blood oxygen levels may be lower. However, studies have shown that yawning does not actually increase oxygen levels in the blood.

Another theory is that yawning helps to regulate brain temperature. This theory is based on the observation that people yawn more when they are hot or stressed. However, studies have shown that yawning does not actually have a significant effect on brain temperature.

Some researchers believe that yawning is a form of social bonding.

The correct option is D.

Writing a Claim Letter. (Marks 05 – Time required: 25 minutes) When President Carlos Menem of Argentina took office in 1989, he and his economy minister Domingo Covallo decided that competition from foreign producers would stimulate Argentine businesses to provide better products at competitive prices. To the delight of Argentine shoppers, the import tariffs were lowered and goods began pouring in from all over the world: calculators and copy machines, scissors and automobiles, bicycles, toothpicks – and peaches. When Menem’s new policies took effect, California peach growers responded eagerly to the opening of the new market. Individual growers banded into the California Peach Growers Association to ship their fruit to Edcadassa, the Argentine firm that oversees all imported goods while they await customs clearance at Ezeiza international airport. As supervisor of the Argentine project for the growers association, you were extremely pleased with success of the first few shipments; everything had gone smoothly. Then word came back from angry Argentine buyers that the fresh Californian peaches they had expected arrived at their stores ready for the garbage bin. They refused to pay for the rotten fruit, and your growers lost $ 50,000. You made inquiries and discovered that Edcadassa was overwhelmed by the level of imported goods flowing into Argentina, (an average of 150 tons a day, compared with 60 tons two years before). Your peach shipment was lost in the confusion, and by the time it was cleared through customs, three weeks late, the peaches were already rotten. Since you had shipped the fruit when it was at the perfect stage to make the journey, await the normal customs delay, and ripen gently in the supermarkets of Buenos Aires, you believe the responsibility for the shipment’s destruction rests with Edcadassa. YOUR TASK: Write a letter to Edcadassa ( Columbia 4300, 1425 Buenos Aires, Argentina) requesting full compensation for the ruined peaches.

write a diary entry on petting a dragon ​

Answers

Answer:

Dear diary,

My life was almost in danger today. As I walked deeper and deeper into the forest, the aroma of smoke spread throughout the air. Looking around hesitantly, I hoped my parents hasn't noticed my disappearance. I tried to quietly walk through the trees and vines. The fragile branches breaking beneath my boots regardless. To my surprise, there lay a deep cave. Out of curiosity, I walked in, searching for who knows what. "H-hello?" I asked into the distance. My shaky voice echoed within the cave. There was suddenly a loud noise. It was the sound of a loud breath. "What's in there?" I thought. I walked further and further into the cave to see a terrifying, red scaled dragon! I put my hands over my mouth to stop myself from screaming. The dragon was fast asleep. I hesitantly crept closer to it. I let one of my hands loose and dragged it closer to the dragon. "No, I shouldn't touch it," my conscience told me. But I ignored the voice in my head and touched the dragon. It's scales were such a vibrant color. As my hand moved across it's scales, the dragon's eyes opened, and a terrified look spread across my face.

Dear diary,

I pet a dragon today. It wasn’t like petting a dog, I can tell you that. The feeling of every touch was scaly and dry. It felt like glossy pebbles had been sitting in the sun for too long. The dragon was a lime green with bright red flares along its back. I was lucky enough not to catch a fire ball. When the dragon flew away, the gust from its wings knocked me down. It was all pretty sick.

SINGLE-CROP FARMING IS LEAVING WILDLIFE WITH NO ROOM TO TURN

Answers

Answer:

True.

Explanation:

Monoculture is not something that happens naturally in nature. This is because, the natural state of nature presents itself as a space with a vast diversity of plants and animals, even in regions where there is a predominance of a single species, we can see that there are other different species coexisting in smaller quantities. In this natural environment, wildlife finds all the necessary resources for their survival and they manage to make this space their home.

However, once the monoculture is installed in a region, all the diversity of plants is removed to make room for the culture that will be placed there. When this diversity is removed, the wildlife does not find the resources necessary for its survival, because there is only one resource, the cultivated agricultural culture, and this unique resource is not enough to maintain wildlife in the region, which causes that all individuals migrate or die.

is america a nation that unifies ideas and people or does american society fail to find unity? Explain

Needs to be 8 sentences.
Write examples of life experiences or information you have heard to prove your point.

Answers

Answer:

American society has a flaw in generating unity among its citizens. This is clearly seen in issues such as the political division between Democrats and Republicans, racism towards African Americans and Latinos, or the lack of acceptance of certain cultural manifestations.

These examples show that, although America is a nation that accepts differences among its inhabitants and protects diversity, its society has some problems inherent in these differences that compromise social stability and generate clashes of cultures.

A clear example of this situation is the Black Lives Matter movement, generated as a result of George Floyd's death at the hands of the police. This movement has put on the table the situation of inequality between African Americans and whites in the United States, and it is a sign that social unity and complete equality have not yet been achieved in America.

Not only that but they're teenagers and should be able to have the freedom of being able to wear whatever they would like. I'm not saying they should wear small clothes and crop tops that show more than half of their stomach but they should have a dress code that isn't strict, Not uniforms. They should be able to wear what makes them comfortable not everyone wants to wear the same clothing, Not everyone is comfortable wearing uniforms. Those are my main three reasons why High Schoolers shouldn't be able to have to wear uniforms.

Answers

Answer:O It is the climax of the story, which provides excitement and suspense for the reader.

Explanation:

The effect that Mathilde's borrowing the necklace have on the plot of "The Necklace" is;

It is the rising action that leads to her losing the necklace and searching for a solution

The rising action of a story is the point when the tension rises in the story. It comes immediately after the exposition and ends in the climax.

The exposition of the story is developed when the author describes the attributes of Mathilde.

In the rising action, tension begins to be built as we see Mathilde borrowing a piece of expensive jewelry from Madame Forestier.

We know that any mishandling of the jewelry from this point can lead to problems. So suspense begins.

It proceeds to the climax, the turning point in the story when the jewelry is lost.

In the beginning of "The World on Turtle's Back," why did the husband become "terrified"? He was terrified the he might never see his wife again. He was terrified that his wife might fall through the hole in the sky. He was terrified that he would be punished for marring a sacred tree. He was terrified that the Great Tree would fall into the ocean.

Answers

Answer:

He was terrified that he would be punished for marring a sacred tree

Explanation:

Yes

In the beginning of "The World on Turtle's Back," we can see that a character named just as "husband" is terrified of being punished for having destroyed the sacred tree that lit up the world where he lived.

"The World on Turtle's Back," is a myth created by the Iroquois to explain the origin of the earth and living things. In this myth, we can see:

There was a realm above the heavens that was created even before the earth was created.This realm was inhabited by magical beings who did not die, grow old, or get sick. They were called the people of heaven.There was a tree in the center of that realm that was holy.The tree lit up the entire kingdom, since the sun did not exist.

One day, one of the women of the heavenly realm discovered that she was pregnant with twins. She is very happy and tells her husband, but he is furious with the news, to the point of pulling the sacred tree from the ground. This causes a hole and he throws his pregnant wife into that hole.

The man is terrified, not because he threw his wife to an unknown end, but because he destroyed the sacred tree and is afraid of being punished.

Despite the fall, the woman survives and gives birth to the twins who will create all the elements of planet earth.

With this, we can conclude that the Iroquois also created myths to explain things they did not know, such as the origin of the planet and human beings.
