Demonstration version of the exam in biology of the year. Evaluation of tests in biology of the Unified State Examination

Final exams not far away. It's time to start intensive preparation. Including those who have decided to take the Unified State Exam as their choice. Quite a few this year, as in previous years, will choose biology for this year. So now we’ll talk about what awaits graduates in the Unified State Examination in Biology in 2018.

Relevance of the discipline

Who is most likely to take the Unified State Exam in biology in 2018? First of all, those students for whom such specialties as biologist or biotechnologist, ecologist, biophysicist, zoologist, paleontologist, and veterinarian are desirable.

The discipline is also considered mandatory for those who dream of becoming a doctor and are planning to storm medical universities. A strong knowledge of biology and a high exam score in the subject are also required for future psychologists, psychoanalysts, psychotherapists, and defectologists. Another specialized area: universities and departments of sports orientation.

Dates for the Unified State Examination in Biology in 2018

As usual, to the graduates of 2017-2018 school year will have to take the Unified State Exam in Biology, which has three stages.

The preliminary exam, which is expected on April 4, 2018, can be attended by graduates of previous years or current schoolchildren who have documented that they will not be able to meet the main requirements. Unified State Exam dates. There is also a reserve - April 11.

For those who experience force majeure that prevents them from coming to the exam at the usual time, the option of an additional chance is left. Students who can prove that they missed the main stage for a good reason will be able to take this exam in September.

How did past graduates cope with the subject?

About 7% of all graduates choose this subject for the Unified State Exam.. In addition, over the past few years their number has decreased: from 129 thousand in 2016 to 112 thousand in 2017.

There is another alarming figure: 18% of schoolchildren failed the last biology exam in 2017. There were approximately the same number a year earlier, even a little more: by 0.3%.

The main group of graduates passed this exam with a C, gaining an average of 53.2-53.8 final points.

Are there any innovations expected in the Unified State Exam in biology in 2018?

Should this year's graduates and future applicants expect significant changes in the Unified State Examination in Biology in 2018? Hardly. If there are adjustments, they will be minimal and insignificant. Since in 2017, the KIMs on this subject were seriously improved.

The test format questions disappeared from them, where it was enough to choose, even at random, one answer option from those provided in the KIMs.

The number of questions has decreased, and much more: there are now 28 versus the previous 40. You need to master these tasks in 210 minutes. The approximate “storyboard” is as follows: it is optimal to spend approximately 5 minutes on each of the questions in the first section and 10-20 minutes on each task in block 2.

New requirements have appeared for the tasks of the first block; new types of tasks are included here, the implementation of which requires specific skills: skills in working with tables and various graphical diagrams, including charts and graphs. The ability to perform both analysis and synthesis of available information is also desirable.

Contents of examination CIMs

In this test, the graduate is required to show how he has mastered the material on the development and structure of plants, fungi, lichens, and animals. The basics of human structure and functioning will also be presented with ticket questions. Students are also expected to know the basics of the theory of evolution, understand general biological patterns, have a deep understanding of the structure and functions of cells, etc. An important section of knowledge in the subject are topics related to the biosphere and ecology of the planet.

Block No. 1. The maximum points that an 11th grader can score is 39. There are 21 tasks for choosing answers and the ability to produce comparative analysis, solving problems on genetics and the basics of cytology, there will also be analytical work with tables and figures. You need to act quickly, and your answers need to be extremely brief.

In the second block Completing tasks requires voluminous, complete answers. But for these 7 tasks you can get 20 points. Total we get 59 primary points, translated into the final result they will amount to 100 points. And for a satisfactory result you need a minimum of 36 points.

Optimal preparation for the Unified State Exam in biology in 2018

Science is not easy, it requires care and understanding, and not just rote memorization. Therefore, preparation is needed methodically, constantly, and not from time to time, and not in an emergency on the eve of the exam.

Basic training includes the study of terminology; without knowledge of it, it is difficult to navigate biology as a science. To make memorization easier, use visualization techniques, that is, support the theory with illustrative material, look for pictures, graphs, diagrams, which will become the basis for associative memory work.

Ask questions to your teacher and classmates who are knowledgeable about the topic. Practice tests from previous years, as well as new demo versions of the exam. Tune in for a positive result!

Unified State Examination scores and grades in biology in 2018

To the usual school system Unified State Examination points are translated as follows:

• “two”, unsatisfactory result, corresponds to 0-35 points;
• “C” was earned by examinees who scored 36-54 points;
• “four” – this is how you can translate the sum of points in the range from 55 to 71;
• “excellent”, a five-star result becomes the property of schoolchildren with an exam result of 72 points or more.

The minimum required for successful, albeit satisfactory, passing of the exam is 36 points. At the same time, to enter a profession that is far from prestigious and not on a budget, you must at least have a certificate with 50 points. High-quality universities have much higher requirements: only those whose Unified State Examination score in biology is 84 points or more will be accepted into the budget form of education.

How will the Unified State Examination in biology be organized in 2018?

All auxiliary materials that are required to work with CMMs will be provided by the exam organizers, You cannot bring anything from reference or illustrative literature with you.

Phones, tablets and other gadgets are also illegal. If anyone is hoping for cheat sheets or tips from a wise neighbor, then do not forget: the examining committee is very vigilant, and 100% of the classrooms in which the Unified State Exam in biology will be held in 2018 are promised to be equipped with online monitoring systems.

In addition, work continues to prevent information leaks. In particular, more and more schools are choosing a format where exam tickets are printed on the spot, and accidents and deliberate fraud during the delivery and transportation of CMMs are excluded. It is believed that already in 2019, all schools will switch to the new algorithm for printing tickets, and examination classes will be equipped with the appropriate equipment.

Answers and solution – Demo version of the Unified State Exam 2018 BIOLOGY project

Part 1

Exercise 1. Hereditary variability can be mutational or combinative. Answer: Combinative

Task 2. A cytogenetic research method is an analysis that can be used to determine existing changes in the chromosomal apparatus. Simply put, this is what we can see under a microscope. We cannot determine 1, 2, 5 using this method. Only 3 and 4 remain. Answer: 3 and 4

Task 3. In a somatic cell - 2n, in a reproductive cell - n. 56/2=28 Answer: 28

OR 50–18=32 Answer: 32%

Task 4. It's clear before us plant cell(large vacuole, platids and cell wall). We need to write down 2 “outliers”, which means 1 is not suitable, because they are shown in the picture, 3 is not suitable because it is a plant cell, it is capable of photosynthesis, 5 is also not suitable, because this is inherent in all cells. 2 is suitable for us, as it is inherent only in an animal cell, and 4 is also suitable, since phagocytosis cannot take place due to the thick cell wall. Answer: 24

OR 1,4 and 5 refer to the DNA molecule. 2 – messenger RNA, 3 – ribosomal RNA. Answer: 2.3

Task 5. Oxygen-free cleavage occurs in the cytoplasm of the cell. It is also called anaerobic respiration (glycolysis) or fermentation. The term "fermentation" is usually applied to processes occurring in the cells of plants or microorganisms. At this stage, further breakdown of substances continues with the participation of enzymes. For example, in muscles, as a result of anaerobic respiration, a glucose molecule breaks down into two lactic acid molecules. Phosphoric acid and ADP are involved in the breakdown of glucose and, due to the energy released as a result of their breakdown, ATP molecules are formed.

In yeast fungi, the glucose molecule under oxygen-free conditions is broken down into ethyl alcohol and carbon dioxide. This process is called alcoholic fermentation.

In other microorganisms, the process of glycolysis ends with the formation of acetone, acetic acid etc. In all cases, the breakdown of one glucose molecule is accompanied by the formation of two ATP molecules. During the oxygen-free breakdown of glucose to form lactic acid, 40% of the released energy is stored in the ATP molecule, and the rest of the energy is dissipated as heat.

The third stage of energy metabolism is called aerobic respiration, or oxygen splitting. This stage of energy metabolism is also accelerated by enzymes. Substances formed in the cell at previous stages, with the participation of oxygen, decompose into the final products CO2 and H2O. During oxygen respiration, a large amount of energy is released, which accumulates in ATP molecules. When two molecules of lactic acid are broken down in the presence of oxygen, 36 molecules of ATP are formed. Consequently, aerobic respiration plays the main role in providing the cell with energy. All living organisms, according to the method of obtaining energy, are divided into two large groups: autotrophic and heterotrophic.

Phenotypic split 3:1. Answer: 31

Task 7.

The gonad is an organ in which sex cells are formed or (as in higher vertebrates and humans) only reproduce, grow and mature.

Fertilization is the process of fusion of male and female reproductive cells, resulting in the formation of one cell, which is the beginning of a new organism.

Oogenesis is the development of the female reproductive cell - the ovum (egg).

1, 3, 4 refer to sexual disunion. 2.5 are classified as asexual. Answer: 25

Task 8.

Hereditary variability Hereditary variability (genotypic variability) is caused by the occurrence of different types of mutations and their combinations, which are inherited and subsequently manifested in the offspring.

Modification (phenotypic) variability - changes in the body associated with a change in phenotype due to influence environment and are in most cases adaptive in nature. The genotype does not change.

Answer: 11212

1 - ectoderm - the outer germ layer of the embryo in the early stages of development.

The ectoderm forms the nervous system (in vertebrates: the spinal cord, peripheral nerves and brain), tooth enamel and epidermis (skin epithelium). It also forms the sensory organs, the epithelium of the anterior and posterior sections of the digestive system.

2 - mesoderm - or mesoblast - the middle germ layer in multicellular animals (except sponges and coelenterates). Located between the ectoderm and endoderm.

The notochord, cartilaginous and bone skeleton, muscles, kidneys, and blood vessels are subsequently formed from the mesoderm.

Task 10.

The roots of the vast majority of plants perform six main functions:

1. Roots hold the plant in a certain position. This function is obvious for terrestrial plants; it is especially significant for large trees with large mass branches and leaves. In many aquatic plants, fastening to the bottom allows the leaves to be advantageously distributed in space. In floating plants, such as duckweed, the roots prevent the plant from turning over.
2. The roots provide soil nutrition to the plant, absorbing water from the soil with minerals dissolved in it, and conducting substances to the shoot (Fig. 1).
3. In some plants, reserve nutrients such as starch and other carbohydrates are stored in the main root.
4. Formation occurs in the roots certain substances, necessary for the plant body. Thus, in the roots, nitrates are reduced to nitrites, and some amino acids and alkaloids are synthesized.
5. Roots can carry out symbiosis with fungi and microorganisms living in the soil (mycorrhiza, nodules of representatives of the legume family).
6. With the help of roots, vegetative propagation can be carried out (for example, by root suckers). Plants such as dandelion, plum, raspberry, and lilac reproduce by root suckers.

Main functions of the sheet:

• photosynthesis;
• breath;
• transpiration.

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 Culture, 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 - 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 specific requirement educational institution– this information needs to be clarified at 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. School course begins in grades 5-6, so you will have to “dig deep” when preparing.
• Difficulties are also associated with the structure of the exam. Not necessarily high quality theoretical knowledge guarantee successful passing 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,

SPECIFICATION
control measuring materials
single state exam 2018 in BIOLOGY

1. Purpose of KIM Unified State Exam

The Unified State Exam (hereinafter referred to as the Unified State Exam) is a form of objective assessment of the quality of training of persons who have completed secondary education programs general education, using tasks of a standardized form (control measuring materials).

The Unified State Examination is conducted in accordance with the Federal Law of December 29, 2012 No. 273-FZ “On Education in the Russian Federation.”

Control measuring materials make it possible to establish the level of mastery by graduates of the Federal component of the state standard of secondary (complete) general education in biology, the basic and specialized level.

The results of the unified state exam in biology are recognized educational organizations average vocational education and educational organizations of higher
vocational education as results entrance examinations in biology.

2. Documents defining the content of the Unified State Exam KIM

3. Approaches to selecting content and developing the structure of the Unified State Exam KIM

The basis for the development of the Unified State Exam KIM is the invariant core of content biological education, which is reflected in the Federal component of the state standard of secondary (complete) general education, various sample programs and textbooks recommended by the Russian Ministry of Education and Science for use in the implementation of those with state accreditation educational programs secondary general education in biology.
KIM Unified State Exam tests graduates’ mastery of knowledge and skills in the main sections of the biology course: “Plants”, “Bacteria. Mushrooms. Lichens”, “Animals”, “Man and his health”, “ General biology" This allows the test to cover the main content of the course and ensure the content validity of the CMM. The content of the KIM Unified State Exam does not go beyond the biology course high school and does not depend on what program and what textbook is taught in a particular educational organization.

The examination work is dominated by tasks in the “General Biology” section, since it integrates and generalizes the factual knowledge acquired in basic school, and examines general biological patterns that manifest themselves at different levels of the organization of living nature. These include: cellular, chromosomal, evolutionary theory; laws of heredity and variability; ecological patterns of biosphere development.

Assignments that control the degree of mastery of knowledge and skills cover the most significant issues in the content of the biology course and test the graduates’ level of scientific worldview and biological competence.
