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.

Research on humans tells us that people who are more empathetic tend to be more susceptible to contagious yawning. When you see someone else yawn, the networks in your brain responsible for empathy and social skills are activated. :)

Explanation:
Meatloaf is a dish of ground meat that has been combined with other ingredients and formed into the shape of a loaf, then baked or smoked.
What is the meaning of Meat?Meat is the flesh or other edible portions of animals (often domesticated cattle, pigs, and sheep) consumed for nourishment. This includes the tendons, ligaments, as well as muscles, and fat.
Meat is typically defined as any flesh from a warm-blooded animal, including cattle, hog, lamb, and veal. Fish are not regarded as flesh by this definition because they have cold blood.
A vegetarian does not consume any meat at all, not even fish or fowl. The diet of a lacto-ovo vegetarian includes both dairy and eggs. A lacto vegetarian consumes dairy but avoids eggs. Ovo vegetarians consume eggs but not dairy.
The dish known as meatloaf is made of ground beef that has been mixed with additional ingredients, molded into a loaf, and baked or smoked. The final form is either pan-formed by baking it in a loaf pan or hand-formed on a baking sheet.

Answer: Write a 14 word sonet
Explanation:
My cat stares blankly at the wall Trying to hunt the light.She flicks her tail and starts to crawl, Eyes focused, fur upright.I watch her, silently, as she creeps Slowly towards her prey.I remain still, as if fast asleep For this is not child’s play.Her moving stops, she is readyTo jump up and attack.I see her ascend, now unsteady; I gasp, and she looks back. Her eyes are chasms, black holes throughout,And my flashlight goes quickly out.
