Unified State Exam in Biology option 1. Preparation for the Unified State Exam in Biology online - Materials

On this page you can take biology tests online, compiled by a professional teacher taking into account the current requirements for knowledge of the subject. Don't miss the opportunity to test your knowledge of biology in order to brush up on topics that are difficult for you before the exam!

Understanding the mechanism of mitosis, indirect cell division, is of great importance for passing the Unified State Exam in biology with a high score. Knowledge of how mitosis occurs is required not only to answer many test tasks, but also to solve problems in cytology (question 27). These tests present only a few tasks examining mitosis, but throughout the history of the Unified State Exam there have been a lot of them. Mitosis is directly related to meiosis. The complex life cycles of different organisms contain a natural alternation of the processes of mitosis and meiosis.

The process of meiosis, reduction cell division, is understood by many students even less well 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 tasks, you need to explain the events of meiosis in detail and in detail. Specifics are important, not general phrases. Examples of questions examining meiosis: “Which chromosomes are characterized by independent segregation? What significance does it have?”, “Why are the reasons for combinative variability also embedded in meiosis?”

Ontogenesis is the most important topic in biology, considering the development processes of living organisms. Just 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 at a loss?

Genetics is one of the most complex branches of biology. According to the 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 10th-11th grades. For the Unified State Exam in biology, many problems on 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 complexities 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 different organisms, to draw conclusions about at what point in historical development complications in structure and function appeared. Any stage of evolution could be characterized by different directions - aromorphosis, idioadaptation, general degeneration. Hundreds and thousands of different groups of living organisms have undergone these trends over 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 connections between different organisms and be able to draw conclusions about at what point in historical development complications in structure and function 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? Test yourself!

The topic “Brain” is one of the most interesting and difficult in biology. The structure of the human nervous system is traditionally poorly understood by students due to the large amount of information. The nervous system controls a huge number of structures in the body. Examples of Unified State Exam questions on this topic: “Which part of the brain is responsible for the final formation of visual sensations?”, “Which part of the brain regulates body temperature and is the center of thirst and satiety?”, “Where are the centers that govern human conscious behavior located?”, “What is the function of the midbrain?”, “Which human brain controls metabolism?”.

A lack of understanding of the differences between the structures of the autonomic and somatic nervous systems is typical for many students. This can be critical when answering exams. Thus, in the second part of the 2016 Unified State Exam tasks, 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 of the basic concepts of the “Nervous System” section, 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. Take online tests and improve your knowledge.

Benefits of Test Preparation

Online tests for the Unified State Exam in biology as a method of repeating accumulated knowledge have a number of advantages, among which are the following:

• ease of use - you can prepare for the Unified State Exam using tests by simply sitting at the computer and marking the correct answers, while you have no fear that the teacher will suddenly ask a provocative question, the results will not be affected by anxiety, etc.;
• eliminating errors during testing due to fatigue, etc.;
• reduction in labor intensity.

Online tasks allow you to cover all topics of the discipline, in contrast to an oral exam, during which the teacher is not able to devote much time to one student to check the level of his knowledge.

Do not miss the opportunity to prepare for the 2016 unified exam with the help of test tasks compiled by the tutor of the year (2015) - Yaroslavtsev V.Yu., who has already helped hundreds of schoolchildren enter the universities of their choice. Write to us by email or call the numbers listed on the website! We will be happy to answer all your questions!

The Unified State Exam in biology is taken at the choice of a student who plans to enter a higher education institution with a certain specialization. In terms of popularity, this subject ranks 5th-6th every yearplaces, about 18% of schoolchildren pass it. Which universities require biology? This subject is taken in educational institutions in the following areas: medicine, biology, pedagogy with the specialty “Biology teacher”, agriculture, veterinary medicine, physical education, psychology, garden design, ecology, technical specialties where biology borders on physics. Professions: psychologist, ecologist, athlete, engineer, doctor.

The work consists of tasks that are conventionally divided into two parts. In 2018, there were 28 tasks: 21 - tests, you need to choose an option from the proposed ones, 7 - of increased complexity, you need to give a detailed answer.

The work is given 210 minutes - the student decides independently how to allocate time for answers.

The threshold score for admission to various universities depends on the requirements of a particular educational institution - this information must be clarified with the university.

• The first part contains tasks on knowledge of theory and the ability to use this knowledge. Types of tasks in the first part: multiple choice (can be accompanied by a picture), establishing a logical sequence, solving problems, adding data to a table, analyzing data.
• The second part aims to identify the characteristics and depth of knowledge of the subject. The purpose of such tasks is to test the ability to establish cause-and-effect relationships, draw conclusions, use theory in practice, justify one’s position, and think logically. It is this part of the test that is key in the selection process of potential university students.

The first part is checked automatically using a computer. The second is analyzed by specialists.

How difficult is the biology exam?

• The main difficulty is the significant amount of information that needs to be repeated. The school course begins in grades 5-6, so when preparing you will have to “dig deep.”
• Difficulties are also associated with the structure of the exam. High-quality theoretical knowledge does not necessarily guarantee successful passing of the Unified State Exam - you need to learn how to perform certain types of tasks. You can learn this with the help of a professional tutor or by taking an online test. Every year, tasks of a new type are introduced into the structure - you need to be prepared for this.
• The most difficult topics are: photosynthesis, DNA, energy metabolism. It is better to contact a tutor for these sections and assignments on this topic.

How to effectively prepare for the exam?

• The main thing is to listen carefully in class and study textbooks. This will provide a solid basis for successfully passing the exam.
• Planning: systematic preparation requires a stable and thorough study of the material of the Unified State Examination program.
• Self-education: read reference books, on one's own.
• Take the online test.

The main advantage of online testing is the opportunity to develop the ability to solve tasks of different types and levels of complexity to the point of automaticity, and to correctly allocate time during the exam. It is recommended to prepare for the second part with a teacher or tutor.

The biology exam is selective and only those who are confident in their knowledge will take it. The Unified State Exam in biology is considered a difficult subject, since it tests the knowledge accumulated over all years of study.

The Unified State Exam (USE) tasks in biology are of different types; solving them requires solid knowledge of the main topics of the school biology course. Based on this, teachers developed over 10 test tasks on each topic.

Topics that need to be studied when completing assignments, see from FIPI. Each task has its own algorithm of actions that will help in solving problems.

Changes in KIM Unified State Examination 2019 in biology:

• The model of the task in line 2 has been changed. Instead of a multiple choice task worth 2 points, a task on working with a table worth 1 point has been included.
• The maximum primary score decreased by 1 and amounted to 58 points.

Structure of Unified State Examination tasks in biology:

• Part 1– these are tasks from 1 to 21 with a short answer; approximately 5 minutes are allotted for completion.

Advice: Read the wording of the questions carefully.

• Part 2– these are tasks from 22 to 28 with a detailed answer; approximately 10-20 minutes are allotted for completion.

Advice: express your thoughts in a literary manner, answer the question in detail and comprehensively, define biological terms, even if this is not required in the assignments. The answer should have a plan, not write in continuous text, but highlight points.

What is required of the student in the exam?

• Ability to work with graphic information (diagrams, graphs, tables) - its analysis and use;
• Multiple choice;
• Establishing compliance;
• Sequencing.

Points for each USE biology task

In order to get the highest grade in biology, you need to score 58 primary points, which will be converted to one hundred on the scale.

• 1 point - for tasks 1, 2, 3, 6.
• 2 points - 4, 5, 7-22.
• 3 points - 23-28.

In 2017, a new model of the KIM Unified State Examination in Biology was adopted, aimed at increasing the diversity of tested aspects of biological training of graduates.

Each version of the examination paper consists of two parts. The tasks in the variant are presented in continuous numbering mode. The structure of the examination paper has been optimized:

1. The number of tasks in the examination paper has been reduced from 40 to 28.
2. In Part 1, new types of tasks are proposed, which differ significantly in the types of educational actions: to fill in the missing elements of a diagram or table, to find errors in a drawing, to analyze and synthesize information, to analyze graphs and tables with statistical data.
3. The maximum number of primary points has been slightly reduced: from 61 in 2016 to 59 in 2017.
4. The time to complete the job has been increased from 180 to 210 minutes.

In Part 2, the number and types of tasks with detailed answers remained unchanged - 7 tasks.

Particular emphasis is placed on the formation of methods of activity: mastering methodological skills; application of knowledge in explaining biological processes and phenomena, mastering the skills to solve biological problems. Testing the skills of working with biological information is carried out through its presentation in various ways (in the form of texts, drawings, diagrams, tables, graphs, diagrams).

In 2017, it is planned to exclude all tasks with a choice of one answer from the Unified State Examination in Biology. This is explained by the presence of the following significant shortcomings in them: the uniformity of the form of presentation of the content being tested, the inability to create tasks of a problematic or creative nature; lack of capacity to test students' practical skills; difficulty in identifying true gaps in mastering the content among Unified State Examination participants. A significant disadvantage of tasks with a choice of one answer is also the presence of an element of chance, guessing the correct answer.

As a comparative analysis of the Unified State Examination results over the past two years has shown, the reduction in the number of tasks in the examination paper with the choice of one correct answer from 36 to 25 did not lead to a noticeable decrease in Unified State Examination results. The share of USE participants in biology who did not score the minimum number of points remains approximately at the same level, within the limits of statistically acceptable errors.

Significant modernization in the form and structure of the CMM required adjusting the approaches to constructing the examination paper and including tasks of a new format.

In Part 1 of the new format exam paper, only short-answer tasks have been retained, but their number has been increased, and in some cases the form of their presentation has been significantly changed compared to previous years. It is known that tasks with a short answer allow not only to test a larger volume of content of an academic subject, but most importantly, to provide for the assessment of general academic and subject skills (comparison, generalization, classification, systematization, explanation, solving educational and practical problems, etc.), which corresponds to modern trends in the development of general education.

Along with the preservation of existing tasks, new biological tasks appeared, and the range of tasks with drawings expanded.

As an example of a modernized task, we give task 3 (here and below are tasks from the project of the CMM demonstration version).

This is a computational biological problem. The task was created on the basis of tasks with a choice of one answer that are traditional for the KIM Unified State Exam in biology. In the new edition, the Unified State Exam participant, based on knowledge of genetic information and the chromosomal set of somatic and germ cells, independently carries out all the necessary calculations.

As an example of a task for working with a drawing, we give task 4.

The peculiarity of this task model is that the person being certified is asked to derive two of its characteristic features from a “blind” image of an object (there are no captions for the picture). Moreover, one of the signs given in the task tests knowledge of the morphology of the object, while the second tests knowledge of properties or functions. Such tasks test, in addition to the ability to work with visual information, knowledge in the field of the cell and its vital functions.

Along with well-known or modernized types of tasks, the examination paper includes completely new tasks that test the mastery of the conceptual apparatus by filling in gaps in diagrams, tables, working with graphs, tables, histograms, etc. All of them are aimed at strengthening the activity basis and making the examination work more practice-oriented.

As an example of such tasks, task 1 can serve.

This task allows you to test not only knowledge of the conceptual apparatus of the biology course, but also the ability to establish the subordination and hierarchy of terms (concepts), as well as their internal logical connection.

Let's consider examples of tasks (task 21) for working with information presented in graphical or tabular form, a task for analyzing research results.

It seems that with the help of such tasks it is possible to ensure that graduates have developed the fundamentals of a holistic scientific picture of the world and the ability to analyze, evaluate and generalize scientific information.

The new model of the KIM Unified State Exam is consistent with the existing model of the Unified State Exam 9 in biology. Certain types of tasks, which in a modernized form will be included in the KIM in 2017, have successfully passed many years of testing during the certification of students in basic general education programs and are available in the open bank of OGE tasks. They can become the basis for preparing students for the Unified State Exam in biology in the coming academic year.

As an example of continuity, task 9 can serve.

In the OGE, with the help of such tasks, knowledge of the structure, life activity and significance of animal and plant organisms is tested. In the new model of the Unified State Exam KIM, bacteria and viruses will be added to these objects.

In general, in the exam model of the Unified State Exam 2017, the objects of control, as in previous years, are the knowledge and skills that form the invariant core of the content of the biology course in primary and secondary schools, its sections “Plants”, “Bacteria, fungi, lichens”, “Animals” ", "Man and his health", "General biology". These sections are presented in the Codifier in the form of seven content blocks and requirements for the level of training of graduates of educational organizations for the 2017 unified state exam in biology.
