Biology - where did this name come from? From the Greek words: βίος means "life", and λόγος ─ "teaching". This means that biology is the science of life, of living organisms that live on Earth. Biology studies how organisms are arranged, how certain organs work, how everything grows, develops, reproduces, where organisms come from and why they live in certain places on Earth. And many many others. It is difficult to study all areas of biology at once. Therefore, a number of independent sciences and directions are distinguished. For example, virology is the science of viruses, microbiology is the study of microorganisms, mycology is the science of fungi, botany is the science of plants, zoology is the science of animals, and anthropology is the science of man.
Each of these disciplines is further divided into a number of sciences. For example, in zoology there are such sciences as entomology - the science of insects, ichthyology - about fish, theriology - about mammals, etc. In botany, there are: algology - the science of algae, bryology - about mosses, dendrology - about woody plants, etc.
Biological sciences are closely connected with physics, chemistry, mathematics, geography. All of them are united not only by the subject of study - nature, but also by the methods used by researchers to find answers to all the questions posed.
The most common methods of studying biology are: observation (allows you to describe biological phenomena), another method is comparison (it makes it possible to find something in the structure and life of different organisms), experiment, or experience (helps to study the properties of biological objects in some under certain conditions), modeling (allows you to simulate many processes that are difficult to observe), the historical method (allows you to know the processes of development of wildlife).
So, you understand that biology is not a simple subject, but very interesting, as it lifts the veils of many secrets that people have been interested in since ancient times.
There are a very large number of tall trees on Earth. Trees grow in different parts of the world, which are called the highest on the planet. In some cases, the sizes are exaggerated, but there are also trees that amaze the imagination with their dimensions.
The polar bear is the largest land predator. This most carnivorous and later developed species is a tireless traveler and spends its life wandering the expanses of the Arctic in search of food. Despite its large size, the polar bear is a skilled and fast walker, an excellent swimmer and diver. Thick fur and a thick layer of fat save him from the arctic cold.
I will tell you about the life and behavior of these insects. For many, ants are associated with hard work and strength. These unique creatures have their own hierarchy and laws that help them survive in almost any conditions.
