Science Mysteries: How Many Species Are There?

You might think that after 200 years, the scientists who find, name, and describe Earth's species would be close to finished. But taxonomists, as organized as they may be, have no idea how many species Earth has. Nor can they even provide an educated guess. Although reporting over 16,000 new species every year, taxonomists still cannot predict how many more are undiscovered.

In total, taxonomists have categorized and listed 1.2 million species on Earth. At this point, you would think scientists should be able to use the information they have gathered to make good predictions about how many species an ecosystem can support. This would help them make better predictions about how many species are left to identify. So far, however, the guesses seem to vary so greatly that it seems there is no good theory for making a prediction.

One of the main problems is that most of the places that seem to have a lot of diverse species are in places that are hard to get to. One such place is the ocean, where scientists believe some 80 percent of Earth's creatures are hiding at depths too deep for us to study. In addition, many of the planet's most diverse areas are in remote places with few taxonomists.

Despite all the unknowns, scientists have agreed that there are between five and 15 million species left to discover on Earth. This is a huge range, but whether it's five or 15, taxonomists clearly still have a lot of work to do. And who knows, there may yet be a dragon or a Loch Ness monster left to discover.

Which of the following best paraphrases the paragraph in bold?

It's hard to figure out how many species there are on the planet.
Scientists are having a hard time figuring out how many species there are on Earth even though they know about 1.2 million of them.
Scientists have labeled over one million species on this planet. They could use this information to make predictions about how many other species there are, but they can't agree on a theory.
There are a lot of ways scientists can figure out how many species there are.

Answers

Answer 1

Answer:

Scientists are having a hard time figuring out how many species there are on Earth even though they know about 1.2 million of them.

Explanation:

All the other answers either have missing or wrong information.

For example, "Scientists have labeled over one million species on this planet. They could use this information to make predictions about how many other species there are, but they can't agree on a theory."

But it clearly states in the text, "Despite all the unknowns, scientists have agreed that there are between five and 15 million species left to discover on Earth."

O. Henry's short story "The Ransom of Red Chief" tells the tale of two kidnappers who seize a child who brings them nothing but trouble and leaves them second-guessing their kidnapping plan. Read the excerpt from the short story. Then, respond to the question that follows.

After breakfast the kid takes a piece of leather with strings wrapped around it out of his pocket and goes outside the cave unwinding it.

"What's he up to now?" says Bill, anxiously. "You don't think he'll run away, do you, Sam?"

"No fear of it," says I. "He don't seem to be much of a home body. But we've got to fix up some plan about the ransom. There don't seem to be much excitement around Summit on account of his disappearance; but maybe they haven't realized yet that he's gone. His folks may think he's spending the night with Aunt Jane or one of the neighbours. Anyhow, he'll be missed to-day. To-night we must get a message to his father demanding the two thousand dollars for his return."

Just then we heard a kind of war-whoop, such as David might have emitted when he knocked out the champion Goliath. It was a sling that Red Chief had pulled out of his pocket, and he was whirling it around his head.

I dodged, and heard a heavy thud and a kind of a sigh from Bill, like a horse gives out when you take his saddle off. A rock the size of an egg had caught Bill just behind his left ear. He loosened himself all over and fell in the fire across the frying pan of hot water for washing the dishes. I dragged him out and poured cold water on his head for half an hour.

David and Goliath is a biblical allusion. David was a human warrior who went against the much larger Goliath armed only with a slingshot and some stones. David was victorious. In a short response of 2–3 sentences, explain why the author used this allusion and how it affects the connotation and meaning of this section of text.

Answers

This answer was generated by an AI and may be incorrect.

The author uses the biblical allusion of David and Goliath to describe Red Chief's attack on Bill with a slingshot. The comparison highlights Red Chief's bravery and cunning, despite his young age, and suggests that he is capable of being victorious even against larger and more experienced opponents, just like David was against Goliath. The allusion contributes to the connotation of the text by creating a sense of humor and irony, as the two kidnappers, who thought they had control over the situation, are now being outsmarted and overpowered by a young boy.

The author uses the allusion to David and Goliath to emphasize the power of Red Chief, a small child, over the two kidnappers. The allusion implies that Red Chief is a formidable opponent, despite his size, and that he is capable of causing trouble for the kidnappers. This adds a humorous connotation to the text and emphasizes the irony of the situation.

Write a compare and contrast analysis of how "Broken Chain" and "Fish Cheeks" both address a common theme about belonging. (It needs to be an entire analysis)

Answers

Answer:

"Broken Chain" by Gary Soto and "Fish Cheeks" by Amy Tan are two works of literature that address the theme of belonging. Both works explore the idea that individuals may struggle to fit in and feel accepted, especially when their culture, beliefs, and experiences are different from those around them. The two authors use their own experiences and perspectives to create works that highlight the importance of cultural identity and the challenges of finding one's place in the world.

"Broken Chain" is a story about a young boy named Rafael who wants to belong to a gang. Rafael is of Mexican descent and lives in a neighborhood where gangs are a big part of the culture. He sees the gang as a way to fit in and be accepted by his peers. However, as he becomes more involved in the gang, he realizes that it is not the solution to his problem of feeling like an outsider. Instead, it only leads to more violence and trouble. In the end, Rafael learns that true belonging comes from within and that he must be proud of his cultural heritage in order to feel truly accepted.

"Fish Cheeks" is a personal essay that tells the story of the author's childhood experiences with cultural identity and belonging. Amy Tan grew up in America as a Chinese-American, and she often felt like she didn't belong in either culture. In the essay, she describes a dinner party at her house when she was 14 years old, and she was embarrassed by her family's Chinese customs. She wanted to fit in with her American friends and be accepted by them, but instead, she felt like an outsider. In the end, she learns to embrace her cultural heritage and to be proud of who she is.

In both works, the authors explore the idea that belonging is not just about fitting in with others but about being true to one's self. Rafael and Amy both struggle to find their place in the world, but they ultimately realize that they must be proud of their cultural heritage in order to feel truly accepted. Both works also show that belonging is not a one-time event but a journey that requires self-discovery and the willingness to embrace one's true identity.

In conclusion, "Broken Chain" and "Fish Cheeks" are two works that address the common theme of belonging. Both works explore the idea that cultural identity and self-discovery are essential for finding one's place in the world and feeling accepted. The authors use their own experiences to create works that highlight the challenges and rewards of embracing one's cultural heritage and finding true belonging.

Broken Chain is a short story written by Gary Soto that narrates the story of a young boy named Alfonso, the protagonist. He has crooked teeth. And he wanted to fix his teeth so that when he goes to the swimming in the canal next summer, girls would notice him and boys may think him to be tough.
In the short story, "Fish Cheeks" written by Amy Tan, the narrator wants to change her looks because she fell in love with the minister's son. She wished to have a new American nose and look American.
The theme of both stories is based on appearance. Both the protagonist want to change something in their looks to impress someone. The moral of both the stories is that looks are not everything to impress someone you love.

In "The Lemon Tree Billiards House", Why does Mitch give Locust advice about breaking the curse even though he is uncomfortable?

Answers

Answer:

In "The Lemon Tree Billiards House," Mitch gives Locust advice about breaking the curse of the lemon tree even though he is uncomfortable because he recognizes that Locust is struggling and genuinely wants to help him.

Throughout the story, it is clear that Locust is haunted by the curse of the lemon tree, which he believes has brought him and his family bad luck for generations. He is desperate to break the curse, and he turns to Mitch for advice because he knows that Mitch has experience with the supernatural. Mitch is uncomfortable with the idea of breaking a curse and doesn't believe in it, but he also recognizes that Locust is genuinely distressed and wants to help him find a solution.

Despite his discomfort, Mitch listens to Locust's story and offers him some advice on how to break the curse. He suggests that Locust should try to do something good for the tree, such as planting some flowers around it or giving it some fertilizer. Mitch knows that these actions are unlikely to have any real effect on the curse, but he also understands that they may give Locust a sense of control and help him feel better about the situation.

Overall, Mitch's willingness to offer advice to Locust shows his empathy and compassion for his friend. He recognizes that the curse is causing Locust real distress, and he wants to help him find a way to feel better, even if he doesn't fully believe in the curse himself.
