How tall is a giraffe?

Usually, looking at animals, we are not particularly surprised, but when looking at a giraffe, you involuntarily feel that there is something special in his appearance. The reason for this is probably its long, long neck. The giraffe is the tallest animal on Earth and often reaches a height of 5,5 m.

The giraffe also has very fast legs, and although they are the same length, the strongly developed muscles at the base of the neck give the impression that the spine of the giraffe is sloping from the chest to the tail. A small and narrow head with dark and soft eyes gives this huge animal an expression of tenderness. The large ears of the giraffe are sensitive to the slightest rustle and, together with the sharpest sense of smell, are very important for determining the approaching danger.

The giraffe has an unusually long tongue, sometimes reaching a length of 46 cm, but despite this, the giraffe is so skillful with it that it plucks small leaves of thorny plants without even pricking. If you watch a moving giraffe, you get the impression that he is more likely to hobble than walk. At the same time, a giraffe pursued by someone can reach speeds of more than 50 km / h and overtake the fastest horse!

Being gentle in nature, if necessary, the giraffe can be very dangerous in a fight, kicking with its hind hooves and acting with its head like a sledgehammer. Even a lion tries to be very careful while hunting a giraffe.

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 ... >>

Bees have the ability to clone themselves 28.06.2021

Australian scientists at the University of Sydney have found that a breed of African honey bee is capable of producing nearly identical clones of worker females. This allows insects to avoid the harmful effects of virgin breeding.

The ability to clone oneself has obvious advantages, since there is no need to look for a sexual partner, and there is no genetic dilution in the offspring, that is, the original genome is preserved from generation to generation. Some insect populations have evolved thelitocous parthenogenesis, where females are able to reproduce without fertilizing new females. The phenomenon occurs in some haplodiploid insects, in which males develop from unfertilized eggs and are haploid, that is, they have one set of chromosomes, and diploid females appear with a double set of chromosomes from fertilized eggs.

In haplodiploidy, usually only the queen is able to lay the eggs from which the females emerge. Worker bees, which are also females, in rare cases (for example, in the case of the death of the queen) can only lay unfertilized eggs, from which males always emerge. However, in the Cape honey bee Apis mellifera capensis, due to a single mutation, working females can produce diploid offspring, that is, new working females, without resorting to fertilization.

Thelytic parthenogenesis sometimes results in loss of heterozygosity (where different copies of the same chromosome carry different variants of the same gene) due to genetic recombination resulting in a new combination of genes. Heterozygosity for certain genes is important for sex determination in bees.

In Apis mellifera capensis, workers reproduce only thelytocally, and queens always mate and reproduce sexually. However, this means that the working females had to reduce the recombination frequency in order not to produce homozygous offspring.
