Understanding the mechanism of mitosis, indirect cell division, is of great importance for passing the exam in biology with a high score. Knowledge of how mitosis occurs is required not only to answer many test items, but also for solving problems in cytology (question 27). In these tests, only some of the tasks that consider mitosis are presented, but for the entire the history of the exam there were a lot of them. Mitosis is directly related to meiosis. The complex life cycles of different organisms contain a regular alternation of the processes of mitosis and meiosis.
The process of meiosis, reduction cell division, is understood by many students even worse than mitosis. It has more phases - 8, not 4, as in mitosis. In addition, for living organisms, it has an even more important and subtle meaning. When answering USE assignments it is required to explain the events of meiosis in detail and in detail. Specifics are important, not generalities. Examples of questions regarding meiosis: “Which chromosomes are characterized by independent segregation? What significance does it have?”, “Why are the causes of combinative variability also laid down in meiosis?”.
Ontogeny is the most important topic in biology, considering the processes of development of living organisms. Here, try to answer the questions without hesitation: “In which organisms did the third germ layer appear for the first time in the process of evolution? What organs and systems developed from it? Are you having trouble?
Genetics is one of the most complex branches of biology. By state program about 4-5 months are allotted for the study of genetics at school, its foundations are laid already in the 9th grade, the course continues in the 10-11th grades. For the Unified State Examination in biology, a lot of problems in genetics have been developed, which are placed in the very last question number 40. Is it possible to solve problems perfectly without a deep understanding of the theory? Certainly not. These tests will help you understand the difficulties of genetics.
To understand the stages of evolution, knowledge of zoology and botany is very important. But they alone are not enough. It is necessary to understand the connections between various organisms, to draw conclusions about at what point in historical development complications in structure and functions appeared. Any stage of evolution could be characterized by various directions - aromorphosis, idioadaptation, general degeneration. Hundreds and thousands different groups living organisms have undergone these trends for many millions of years. What are their features? What significance do they have for evolution? Test yourself!
To understand the process of evolution, knowledge of zoology and botany is important, but that's not all. It is necessary to trace the connections between various organisms, to be able to draw conclusions about at what point in historical development complications in structure and functions appeared. Any stage of evolution could be characterized by different directions: aromorphosis, idioadaptation, general degeneration... Hundreds and thousands of different groups of living organisms developed in these ways over many millions of years. What are their features? What significance do they have for evolution?

The topic "Brain" is one of the most interesting and difficult in biology. Structure nervous system of a person is traditionally poorly understood by students due to the large amount of information. The nervous system controls a huge number of body structures. Examples USE questions on this topic: “What part of the brain is responsible for the final formation of visual sensations?”, “What part of the brain regulates body temperature and is the center of thirst, satiety?”, “Where are the centers that control human conscious behavior?”, “What is the function midbrain?”, “Which human brain controls metabolism?”.
Misunderstanding of the difference between the structures of the autonomic and somatic nervous systems is typical for many students. When answering an exam, this can be critical. So, in the second part of the tasks of the USE in 2016, the developers created new questions in which it was necessary to indicate the location of the nuclei and nodes of both the sympathetic and parasympathetic nervous systems. These questions, first of all, require knowledge basic concepts section "Nervous system", such as "dendrite", "neuron body", "axon". Well, for a deep understanding of the topic, you need to know the functions of all parts of the nervous system. Work with online tests and improve your knowledge.
Biology - a set of sciences about wildlife. Its name comes from the Greek words "bios" - life and "logos" - teaching.
The subject of biology studies the structure and functions of living beings, their origin, development and distribution, natural communities, their relationship with each other and environment. All organisms that make up living nature - plants, animals and humans, are considered by biology in their historical development, movement, change and complication.
Suggested tests include questions on general biology, botany, zoology, anatomy, physiology and human hygiene, the basics of genetics, ecology and the biosphere, used in passing the exam and entrance examinations for medical schools.

Biology is a rather extensive field of knowledge, which includes the structure and various processes, both in humans and in animals and plants. In this regard, in order to successfully overcome the final exam, it is necessary to have a wide range of knowledge. Despite the fact that the structure of organisms of various species and classes is similar, they also have differences that must be remembered exactly when answering test questions. Due to the complexity of the exam in biology, it is necessary to prepare even more carefully.
Ways to prepare for the exam in biology
There are many ways to prepare for any exam. Only linguistic technical and humanitarian subjects differ from each other. But the main directions of preparation are preserved. So the exam in biology should not fall out of general course preparation for the single exam. It is necessary to take a comprehensive approach to this issue.
Don't forget schoolwork. In general, the school can do a good job preparing the child for the exam. It all depends on his abilities, memory and psyche. Therefore, you should not write off the school when preparing for the difficult exam in biology.
When choosing training courses To USE It is worth paying attention to the reviews and the existence of the office. If courses have recently opened, then they have less experience and there is a possibility of cheating or closing courses halfway through training. But you can turn to young USE preparation courses if they lure you with low prices and they do not have prepayment. But still, carefully talk with the teachers and decide whether they can prepare you for the exam. On USE results It's not worth saving, but you can't completely refuse the services of young professionals. The main thing is not to waste your money.
Biology tutors will be able to raise the level of knowledge, including helping to prepare for the exam. But you need to choose a tutor more carefully than training courses. The courses have received a state license and have been tested, while anyone can engage in private tutoring. So look for reviews and recommendations before you start paying such a specialist. After all, your time is limited, and it is not worth wasting it. So it's better to spend a couple of days searching a good specialist what to do with someone who can't teach important things.
Trial online USE tests in biology
On educational portal site posted trial options USE in biology, which are available to all visitors. On our site, you can take the test an unlimited number of times, without any time frame. This will allow knowledge gaps to be identified and addressed. So do not forget about self-preparation. After all training USE immerse you in the atmosphere of a test exam, making it more familiar. Repeating tests will help get rid of stress on the exam itself, and this will increase the final grade. In a stressful state, memory works worse and errors are possible. For this reason, it will be beneficial for everyone to take the time to self-study using online USE tests in biology on the educational portal Uchistut.ru.
