Why does a scorpion sting?

Scorpions are very ancient animals. They are quite large, usually 5-10 centimeters long, and some even up to 20. They have a long jointed body and powerful claws. The abdomen of scorpions ends with a swollen last segment, in which a poisonous gland is placed, the duct of which opens at the end of a curved sharp sting.

Scorpions are ferocious predators. A hunting scorpion walks slowly with its "tail" raised, with its claws ajar forward. Due to the nocturnal lifestyle, the vision of scorpions is poorly developed, so the hunter moves by feeling. In this he is helped by special sensitive hairs.

The scorpion is very sensitive to touching any moving object: if it is a suitable prey, it grabs it, if the object is too large, the scorpion retreats, assuming a threatening pose. At the same time, he steeply bends the "tail" and swings it from side to side. If the victim resists, the scorpion stings repeatedly, immobilizing or killing with poison.

Scorpions feed on spiders, centipedes, various insects. Large scorpions can even eat a lizard or a small mouse.

Random interesting fact from the Great Encyclopedia:

When did people start eating eggs?

When people accidentally end up in the jungle or on a desert island for a long time, they are forced to eat what comes across when hunger becomes unbearable. In much the same way, in search of food, ancient man probably tasted bird eggs. It is, of course, impossible to say exactly when this happened. But we do know that chickens have been supplying humans with eggs for food since prehistoric times.

Chickens themselves first appeared in the jungles of India. They spread throughout the world long before the chroniclers appeared, capturing history. Chickens were known in China already 3500 years ago! When the Romans moved north, they found chickens in England, Gaul and among the Germanic tribes. There were no chickens in the Western Hemisphere until Columbus' second voyage there in 1493. Worldwide, chickens produce the bulk of all eggs eaten. In some countries, however, people prefer ducks and their eggs.

Did you know that ducks can beat chickens in an egg-laying competition? There are cases when a duck laid 360 eggs a year. If you count all the chickens in the world and the number of eggs they lay in a year, then for every person on Earth there will be 2 eggs per week.

There are three parts to an egg: white, yolk and shell. Protein makes up about 58% of the weight of the whole egg. It is 87% water and 12% protein. The yolk weighs 32% of the total egg. It contains 49% water, 32% fat and 17% protein. About 10% of an egg's weight is in the shell. Eggs are considered a high quality food because they contain amino acids, mineral salts and vitamins.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

TOSHIBA SATELLITE laptops can now burn DVD-R/RW 09.03.2003

Toshiba has introduced new laptop models from the Satellite series, positioned as a replacement for desktop PCs. Relatively inexpensive machines are equipped with DVD burners.

New items are marked 2455S305 and 1955-S805 and cost respectively 2299 and 2099 US dollars. For this money, the user gets a system on a Pentium 4 processor with 512 MB of memory and a 60-gigabyte hard drive. Other components the same for both machines; NVIDIA GeForce4 420 Go video system with 32 MB video memory, V.92 modem, 10/100 Mbps network adapter from Intel, three USB 2.0 ports and one i Link (IEEE 1394). Notebooks are equipped with DVDR/RW drives. The package also includes Windows XP Home.

The differences between the models lie in the larger diagonal of the screen: the Satellite 1955-S805 has 16 inches with a resolution of SXGA (1365x1024) versus 15 inches for the Satellite 2455-S305 with a resolution of 1024x768. In addition, the processor frequency of the first is 2,53 GHz, the second - 2,4 .XNUMX GHz Both models belong to the category of inexpensive notebooks.

Previously, DVD burning in Toshiba notebooks was only available on expensive systems such as the Satellite 5205-S703. released in October 2002, the company's first mobile computer with a built-in DVD-R/RW drive.

Toshiba's pricing looks better than Apple's other PowerBook offerings, with a 15-inch screen and DVD burner for the same RAM costs $2799 (price from the company's website), and a Sony laptop that also burns DVD sells for $2500 .
