Can animals communicate? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? Can animals communicate? The main means of communication that a person possesses is the word. No animal can communicate with words, but many animals are able to communicate with each other. Many animals make contact by making certain sounds. When a horse neighs or thumps the ground, for example, it means something to the other horse. The hen gives a warning signal to the chicks when they are in danger. A dog communicates in a variety of ways: barks, growls, grunts, whines, bares its teeth, or scratches. Other dogs perceive these sounds and movements. Bees have an amazing ability to communicate. Returning to the hive, they perform a dance that tells the other bees what flowers they have found, where they are, which direction to fly in, and so on. Birds are known to sing. They communicate in this way. There are "dialects" in bird songs. The songs of the same birds in Switzerland, for example, differ from those of the same birds in England. There are even differences between songs in the same country but different parts of it. Many people believe that their pets, dogs, understand human language. In fact, dogs distinguish certain tones of the human voice, not individual words. Interestingly, pets, cats and dogs, have learned to communicate with their owners. They beg for food or meow until the door is opened for them. But wild animals do not express their desires, for example, they do not beg food from each other. But even when animals come into contact with each other, they express only feelings and aspirations, and no real "talk" occurs. Author: Likum A. Random interesting fact from the Great Encyclopedia: How do seeds come about? We all love to smell and look at gorgeous flowers. And it is very difficult to accept the idea that the sole function of a flower is to produce seeds. The petals of the flower contain the organs necessary for the production of seeds. In the very center of the flower is one or more pistils. Stamens are located around the pistils. The pistil is the female part of the flower. It is enlarged downwards. If we cut the pistil in this place, we will find tiny white embryos there. They can develop into seeds if pollination occurs. Pollen is produced in the male organs of the flower - the stamens. At the end of each stamen there are small sacs that contain pollen. In order to form a seed, the pollen from the stamens must reach the ovule, hidden at the base of the pistil. The only way it can get there is through the tip of the pestle, which is called the stigma. Pollen falls on the stigma, sticks and germinates there. A tube runs along the entire pistil, ending in the ovule. This pistil tube is filled with pollen, which reaches the ovule, fertilizes it, and the fruit, the seed, begins to develop. Only plants of the same species are pollinated.
