Science Mysteries: Why Do People Yawn?

Science has given humans many amazing devices and useful bits of knowledge. We know so much about our bodies and how to stay healthy, for example. We also know how to make machines and devices that make life easy for us. Scientists dedicate their lives to knowledge, but even with a lifetime commitment, sometimes scientists fail to find all the answers. One mystery that still remains unsolved is why we yawn-what makes us yawn and what purpose it serves.

Recent studies suggest that we yawn when we get tired as a way to encourage our brains. The theory is that yawning helps cool the brain, allowing it to work more efficiently. According to WebMD's article about these studies, when you yawn, your jaw muscles get stretched, increasing blood flow to your neck, face, and head. Also a deep breath during the yawn forces spinal fluid and blood down from the brain. The cool air then cools down these fluids.

Other scientists believe, however, that yawning is a form of communication. This theory attempts to explain why yawning seems to spread from person to person. This kind of behavior is called "contagious yawning" and carries with it a possible social message. Scientists are not yet sure what exactly the message is, but they believe people who have more social empathy are more likely to start yawning when they see someone else yawning.

Scientists will continue to investigate the mystery of the yawn. Is it a leftover behavior from before humans had language? Was it a "Hey, I'm sleepy. Let's go to sleep" message? Or is it really just a way to keep our brains cool? While this behavior still is largely a mystery, one thing is certain: you are probably fighting the urge to yawn right about now.

Claim: The school should only purchase and drive electric vehicles to help the United States decrease its dependence on foreign oil Which statement is an example of a major counterclaim to address in an argumentative research essay with this claim?

Answers

The question is incomplete, and the full version can be found on Brainly.

Answer: C. Converting to electric vehicles would be too costly for schools that are already facing severe budget problems.

Explanation:

A good counterclaim should directly address the main claim and be based on solid evidence instead of a mere opinion. The idea of electric cars electrocuting drivers is plainly untrue, as there´s no evidence to support it. Claiming that electric cars are ugly or the result of some kind of conspiracy can only be based on personal opinions, and are not a proper counterclaim. Only option C correctly addresses the main claim and provides a valid reason to oppose it. Budget problems in schools are widely known and would probably be a deterring factor for them to able to purchase electric cars.

What can you infer about Igbo customs from Okoye and Unoka's
interactions?

Answers

Answer:

Set around the turn of the century, the novel focuses first on the hero of the book, Okonkwo, and on his late father, Unoka. Okonkwo is a respected leader within the Igbo (formerly spelled Ibo) community of Umuofia in eastern Nigeria. About twenty years ago, Okonkwo distinguished himself and brought honor to his village when he wrestled and threw to the ground Amalinze the Cat, a man who had not been defeated for seven years. Since then, Okonkwo's reputation as a wrestler has grown throughout the nine villages of Umuofia. He is known to be quickly angered, especially when dealing with unsuccessful men like his father, who died ten years ago deeply in debt.

Because of Unoka's laziness and wastefulness, the community had considered him a failure and laughingstock; he was a continual source of deep shame to Okonkwo. Even though he had a family to care for, Unoka frequently borrowed money and then squandered it on palm-wine and merrymaking with his neighbors, thus neglecting his family who barely had enough to eat.

t 1.2.2 Quiz: Understand the Elements of Rhetorio Question 1 of 10 Which term means an attempt to convince others that your position is correct? O A. Fighting B. Logos C. Persuasion D. Permission witch is the best term​

Answers

hey can u help just posted on english:(

The best term that means an attempt to convince others that your position is correct is "Persuasion". Therefore, option (C) is correct.

What is persuasion?

Persuasion is the act of convincing someone to adopt a particular belief, attitude, or course of action. It involves presenting arguments, facts, and evidence in a clear and convincing manner in order to influence the beliefs or behaviors of others. Persuasion is a fundamental aspect of communication, whether in personal, professional, or political settings. Effective persuasion requires a deep understanding of the audience and the ability to appeal to their interests, values, and emotions. It can be achieved through various means, including logical reasoning, emotional appeals, and the use of authority or expertise.

As "fighting" and "permission" do not always involve an attempt to convince someone, and "logos" refers specifically to the use of logic and reason in persuasion, the other options listed are not the best terms to describe this specific act.

In 1968, when the Democratic Party held its convention in Chicago to select a presidential
candidate, the United States was at war in Vietnam. Thousands of Americans and
Vietnamese had died in the war, giving rise to a growing anti-war movement. President
Johnson, a Democrat, declined to run for reelection, in part because of the heavy
opposition to his conduct of the war. Just months before the convention, both Martin
Luther King Jr. and Robert Kennedy were assassinated, contributing to widespread
unrest. Anti-war protesters wanted the Democratic Party to oppose the war, but they
were excluded from the convention. This set off violent clashes between police and
protesters on Chicago streets. The violence at the convention captured the nation's
attention strengthened the peace movement, and led to reforms in the nominating
process.
