U.S. scientists uncover whales"Suicide"Scientists at the Woods Hole Oceanographic Institution in the United States recently studied the bones of sperm whales that were stranded and died, and believed that the cause of their death may have been caused by the process of surfacing to the surface too quickly, thus unraveling the mystery of the long-unexplained mass "suicide" of whales and dolphins. After studying the bones of sperm whales that were stranded to death, two scientists at the institute found that many sperm whale bones had suffered similar damage to divers, that is, they all had bone necrosis, and the situation was very common. After diving or some people working in a hyperbaric chamber due to excessive ascent or improper decompression, it will cause inert gases such as nitrogen or helium remaining in joints or body tissues, which cannot be sent out of the body by blood circulation and form bubbles, causing physical discomfort or acute obstacles.

Sperm whales can dive to a depth of many meters to hunt. Therefore, if they suddenly and quickly float up the shallow sea, nitrogen from the body fluids will gush out to form bubbles. If the air bubbles become tangled in the tissues and compress the nerves, they can block the capillaries, causing their muscles to lack oxygen.

If the bone is affected, the bone tissue will die regionally, leaving multiple small pits. Scientists at the Woods Hole Oceanographic Institution have also found small holes in whale bones that they have studied that have been stranded and killed for years. This suggests that the sperm whale's "suicide" is likely to be the price they paid for their rapid rise in feed.

Scientists have pointed out that marine mammals are actually very fragile, and when they are frightened, they can quickly rise from the depths of the sea and cause them to run aground. Human naval exercises and underwater noise from submarine activities can frighten cetaceans and dolphin mammals, causing them to rise to the surface at an abnormal acceleration, causing them to run aground and die.

The snake's "hot eye" function.

The snake's eyesight is close to zero, but it can detect and accurately capture voles, frogs, lizards and other prey dozens of meters away in the dark night. Scientists have confirmed that this is the result of the snake's ability to "heat locate" the buccal socket between the eyes and the nose.

Snakes are naturally infrared-sensitive, with a camera-like device arranged on their tongue that allows them to "see" mammals emitting heat. Humans can only detect infrared rays if they wear special goggles.

Mathematical abilities of animals.

Scientists have done some interesting experiments, found that bees have their own "fuzzy mathematics", they fly out of the "scout" every morning, come back with "dance language" to tell the direction of the nectar, distance, how much, so the queen bee will "send" the worker bees out to collect honey, the wonderful thing is that the worker bees sent out can be full of honey back to the nest to make honey.

Ants have the ability to calculate accurately. A dead grasshopper is cut into 3 pieces that are twice as large as the small, medium, and large pieces, and when the ants are found, there are 28 in the small pieces, 44 in the medium block, and 89 in the large block, and the number of ants on the large and small pieces is about twice as much.

Chimpanzees count to 10. There was a chimpanzee in the United States who took 10 bananas out of the box and ate them at a time. Once it has eaten 8 sticks, it will continue rummaging until it has eaten 10 sticks before leaving.

Do you know a fish that can explode on its own?

The Gablin shark is a ferocious man-eating shark, its sharp teeth, like an upright triangular scraper, the cold light flickering, especially its snout is longer and sharper than the tiger shark known for its ferocity and cruelty, the appearance is very terrifying, hideous, and makes people shudder. When it was enclosed in a fishing net and struggled several times and couldn't get out, it turned into large and small pieces on its own, and would rather be crushed than captured, which was a bit of an unyielding backbone.

The Gablin shark is a ferocious man-eating shark, its sharp teeth, like an upright triangular scraper, the cold light flickering, especially its snout is longer and sharper than the tiger shark known for its ferocity and cruelty, the appearance is very terrifying, hideous, and makes people shudder. This Gablin shark is known as the "Devil Shark" because it only operates in the deep sea, and its sharp teeth and ferocious ferocity are unusually strong, but few people know its real name.

The Gablin shark is also a very special species of shark. Some modern airplanes or spacecraft and other secrets are equipped with self-detonation devices, which will destroy themselves once they fall into the hands of an enemy or have a major malfunction. Bugarin sharks are also born with this unique instinct.

Gablin sharks.

So until now, no country in the world has ever caught a complete Gablin shark, and no one has even seen a live devil shark. In addition, this shark is very different from ordinary sharks, and the thick skin and flesh are rarely tough and elastic, especially the skin is as hard as ceramic. **The devil shark slice after is like we usually break a piece of porcelain, and the broken joints can be spliced together without any difference.

This devil's bougalin shark trick has left an unforgettable impression on the world.

Is this true? Maybe not really. I guessed. But that's speculation after all! I'd love to know.

What Grandma said was not true.

A few young people were chatting not far away. I heard them talk about the moon and paid attention to their movements.

Come. I saw a young man pointing to the moon, and I looked to his ears.

After a while, I noticed that his ears hadn't fallen out, which was a big deal. I'm going to point to the moon too!

But I just raised my hand halfway up and put it down again. Because I remembered what my grandmother said"The child pointed to the moon ear.

The flowers will fall"The young man pointed to the moon and his ears didn't fall off, but he was an adult, and I was a child!

The stars in the sky blinked, as if laughing at my lack of courage. "If only you could point to the moon and protect your ears.

It's good to have a flower. I thought to myself. Suddenly, I thought of a good way to run into the house and take my dad on a motorcycle.

The helmet was taken and put on the head. Then, plucking up his courage, he pointed to the moon, then tightened his helmet and closed.

on the eyes. After a while, I touched my ear, and oh, it didn't fall off! I was so pleasantly surprised that I ran to my dad at home.

Yell:"Dad, my ears didn't fall out, my ears didn't fall out! "Dad said:"What ears are not falling out? Ears why.

Want to drop? "When I told my dad what my grandmother said, what I thought, and what I did, he couldn't stand up with a smile.

1 The strongest muscle in the human body is the tongue. 2 It is impossible to open your eyes and sneeze. 3.

Right-handers live an average of 9 years longer than left-handers. 4.Crocodiles are unable to stick out their tongues.

5.Polar bears are left-handed. 6.

Fleas can jump 350 times their body length, the equivalent of a person jumping over an American football field. 7.Cockroaches that have their heads off all the time can live for 9 days, and the reason for their death after 9 days is excessive hunger.

8.Giraffes can't cough. 9.

The crocodile's heart beats only 9 times in 1 minute. 10.Owls are the only birds that can distinguish the blue color.

If you find a cockroach in your home, congratulations, there will be almost 20,000 of them in total.

Male mosquitoes do not suck human blood, they feed on plant body fluids.

People shiver when they urinate because a large amount of heat is excreted in the urine when they urinate.

Most of the koalas fell to their deaths from tree branches.

Tigers are actually bai

It's a tree climber, and it's du

Very well, platypus zhi is a mammal dao that lays eggs

The jaguar will take the small prey to play with and eat.

A well-fed anaconda can go months without eating.

The total length of a person's blood vessels can circle the earth two and a half times on average.

The speed of air flow at the moment of a sneeze is faster than that of a typhoon.

Most of Earth's early organisms would have been devastating in the presence of oxygen (we are the descendants of a few oxygen-loving people, and only oxygen can provide enough power to support large organisms).

Shortly after returning to Brunn from the University of Vienna in 1856, Mendel began an eight-year experiment with peas. Mendel first obtained 34 varieties of peas from many seed dealers, and selected 22 varieties for experimentation. They all have some kind of stable trait that can be distinguished from each other, such as tall or short stems, round or wrinkled grains, gray or white seed coats, etc.

Mendel cultivates these peas by artificially and observes, counts, and analyzes the traits and numbers of peas of different generations. The use of such experimental methods requires great patience and rigor. He loves his research work and often points to peas to visitors

These are my children! ”

After 8 years of hard work, Mendel discovered the basic laws of biological heredity and obtained the corresponding mathematical relations. His discoveries are called "Mendel's First Law" (Mendelian Law of Genetic Segregation) and "Mendel's Second Law" (i.e., the Law of Free Combination of Genes), which reveal the basic laws of the mysteries of biological inheritance.
