How the exam works

Tasks. The OGE in biology has two parts and 32 tasks.

Part 1 → 28 tasks with short answer. In the form it is enough to enter one or several numbers with the correct answer, and write down the sequence or correspondence correctly.

In tasks 1–22 you need to choose one of four answer options, in tasks 23–24 - three out of six options.

Task 25: establish a correspondence by matching each element from the first column with the correct number from the second column.

Task 26: establish the correct sequence of elements.

Task 27: insert the correct terms into the text.

Task 28: select the correct characteristics of an object from the proposed list and compose its description according to a given algorithm.

Part 2 → 4 tasks with detailed answers. They require a detailed description of the progress of the solution.

Task 29: answer several questions about the text.

Task 30: work with statistical data and explain in detail the conclusions drawn.

In task 31, based on the conditions of the task, you will be required to select a diet and explain your choice. In task 32 - based on the results obtained in task 31, answer theoretical question, related to the topic of human nutrition.

Course sections. Examination paper in biology covers five main blocks:

1. Biology as a science

2. Signs of living organisms

3. System, diversity and evolution of living nature

4. Man and his health

5. Relationships between organisms and the environment

Requirements. To pass the exam successfully, you need to know:

About the basic methods biological research: description, observation, measurement and experiment.
About the structure, characteristics, functions of cells, tissues, organs and living organisms.
About the classification of plants and animals accepted in biology and the main characteristics of kingdoms, types and classes.
About the structure and functions of organs and systems of the human body.
About ecology and interaction different types in nature.

Time. The OGE in biology lasts 3 hours (180 minutes).

Materials and equipment. You are allowed to take a ruler and a non-programmable calculator with you to the exam.

How work is evaluated

A total of 46 primary points can be obtained in the exam.

1 point → tasks 1–22

2 points → tasks 23–27, 32

3 points → tasks 28–31

You will receive 1 point for tasks 23 and 24 if you indicate only two out of three correct answer options. If only one correct answer or none is selected, no points are awarded at all. If you indicate more options than three in your answer, 1 point will be deducted for each extra number in the answer.

You will receive 1 point for tasks 25 and 27 if you make no more than one mistake. 1 point for task 26 is awarded if the sequence of no more than two elements is mixed up.

In task 28, 1 point is deducted for each mistake. For three or more mistakes you will receive 0 points.

In tasks 29–32, the number of points depends on the completeness and correctness of the answers.

Analysis of tasks 23–32

Tasks 23 and 24

Example assignment

Which of the following properties are characteristic of plants from the Rosaceae family? Choose three correct signs out of six and write down the numbers under which they are indicated.

1. Can be woody

2. Five-membered flower

3. Stipules are absent

4. Fruit - berry

5. Parallel venation

6. Big number stamens in a flower

Solution

To complete the task you need to know characteristic features families, in in this case- Rosaceae family. When preparing for the exam, do short description each family according to the following algorithm.

👉 Be able to identify common and different characteristics of different groups and classes of animals.

👉 Be aware of exceptions.

Answer: 1, 2, 6.

Example assignment

What characteristics are common to birds and crocodiles? Choose three correct answers out of six and write down the numbers under which they are indicated.

1. There is an atlas and an epistropheus

2. Warm-blooded

3. Has a four-chambered heart

4. Laying eggs

5. The end product of nitrogen metabolism is urea

6. Has teeth

Solution

The crocodile is an exception among all reptiles; it has a four-chambered heart, like warm-blooded animals, including birds, so point 3 is correct. In addition, crocodiles and birds have atlas and epistropheus, and they lay eggs.

👉 Focus on keywords in the task.

Answer: 1,3,4.

Example assignment

Which of the listed characteristics of the red-eared slider allows it to be classified as a vertebrate? Choose three correct answers out of six and write down the numbers under which they are indicated.

1. The heart of the red-eared turtle consists of 2 atria and 1 ventricle

2. The cranium-eared turtle’s skull has an anapsid structure, since it lacks temporal fenestrae

3. The central nervous system of the red-eared turtle is represented by the brain and spinal cord

4. The red-eared turtle embryo has a notochord

5. The upper shield of the red-eared turtle’s shell fuses with the ribs and processes of the vertebrae

6. The red-eared slider lays eggs in wet sand

Solution

Look for keywords that will help identify signs that a turtle is a vertebrate: skull, brain and spinal cord, vertebrae (all this is found only in vertebrates.)

Answer: 2,3,5.

Task 25

This task often asks you to establish correspondence between organisms and the stages (or type) of their development, related plants and their characteristics.

👉 When deciding, focus on the number of signs.

Most often, 3 signs belong to one category, 3 to another, but it happens differently. However, if you think that 5 or all 6 characteristics fall into one category, there is most likely an error in your reasoning.

👉 Fill out the table with the answer correctly, be careful when combining letters and numbers.

Example assignment

Establish a correspondence between the listed insects and their types of development. To do this, select a position from the second column for each element of the first column.

Insect

A. Dragonfly rocker

B. Cabbage butterfly

V. Red ant

D. Bed bug

D. Grape aphid

E. May beetle

Type of development

1. Complete transformation

2. Incomplete transformation

Answer:

A	B	IN	G	D	E
2	1	1	2	2	1

Task 26

These tasks often require establishing the correct sequence of taxonomic groups - kingdom, phylum, class, order, family, genus and species. There are also tasks on knowledge of the stages of the life cycle of certain organisms, the order of organs in the human body and the sequence of the experiment.

👉 Pay attention to where to start.

In tasks there is usually a clarification of which element needs to be sequenced. If you skip this and write the correct sequence, but “opposite”, you will receive 0 points.

Example assignment

Establish the sequence of taxonomic units in the crow classification, starting with the largest. Write down the corresponding sequence of numbers in your answer.

2. Corvids

3. Gray Crow

4. Vertebrates

6. Passeriformes

Solution

The largest taxonomic unit in this case is the vertebrate subphylum. It is followed by class (birds), order (passeriformes), family (corvids), genus (crow) and species (gray crow).

Answer: 4, 1, 6, 2, 5, 3.

👉 If there is no such clarification, focus on the conditions of the task and common sense.

Example assignment

Place in in the right order paragraphs of instructions for conducting an experiment proving the use of atmospheric carbon dioxide by plants. Write down the corresponding sequence of numbers in your answer.

1. Plant a pre-weighed willow seedling in a tub

2. Weigh the grown seedling and the dried soil

3. Water the seedling regularly

4. Weigh the dry soil and pour it into the tub.

5. After 5 years, remove the seedling from the tub

6. Place the tub with the seedling in a well-lit place

Solution

Obviously, in this case, the experiment begins with preparing the soil. This is followed by planting the seedling, placing the tub in a lighted place, watering, removing the seedling and soil from the tub and weighing it.

Answer: 4, 1, 6, 3, 5, 2.

Task 27

In this task you need to insert the correct terms into the text.

👉 Use as a hint the case and tense forms in which the terms should appear in the sentence - they also appear in the answer options. Thus, at each point (A, B, C, D) you will have to make a choice not from six, but from two suitable options.

Example assignment

Solution

For point A, the pericardium and myocardium are suitable, for points B and C - diastole and systole, for point D you need to choose between the words “right” or “left”.

The text with correctly inserted terms looks like this:

“The contractions of the heart are carried out by a layer of muscle called myocardium. The cardiac cycle consists of several successive phases: systole atria, systole ventricles and general diastole. Driver heart rate is located in right atrium."

Answer:

A	B	IN	G
5	6	1	2

Task 28

This task requires not so much knowledge as attentiveness. You are given an image of a biological object, animal or plant, and images of certain morphological characteristics of such objects. Looking at the pictures, you need to choose from the list presented morphological characteristics, related to the object specified in the task.

Example assignment

Solution

Let's look at the photo. We determine the squad by comparing the type of wings with the presented list.

Obviously, this is a representative of the order Reticuloptera.

Using the same algorithm, we determine the type of folding of the wings, the shape of the antennae, the type of mouthparts, the shape of the front legs and enter the necessary points into the answer.

Task 29

For this task you are given a text and several questions for it.

Example assignment

1. Where does the puffy duck build its nest?

2. How many eggs can a pair of puffballs produce in a lifetime?

3. Which order does the chick belong to, and how mature are its chicks born?

Algorithm for completing the task

1. Read the text.

2. Find information in it to answer the question.

The answer to the first question is contained in the phrase “The steam hollows out and plucks out a hollow for itself, usually in a rotten trunk of an aspen, birch, or alder.”

A typical mistake: mentioning larch as well. The task asks where the puffball is builds nest, and in larch the bird uses existing hollows.

3. If there is no information in the text itself, determine what data is needed to obtain an answer.

To determine how many eggs a pair of chicks produce in a lifetime, you need to know how long they live, when they begin to bear offspring, how many eggs are in a clutch, and how many broods there are per year. All this data is in the text: the puffball becomes sexually mature in the second year of life and lives up to 9 years. There are usually 6–8 eggs in a clutch; there are no 2 broods per season.

4. Make the necessary calculations.

It turns out that over the course of 8 years, a pair of puffballs lays 6–8 eggs every year. 6x8=48, 8x8=64.

Common mistake: not taken into account important information, in this case, the age at which birds can bear offspring. The number of eggs in a clutch is multiplied not by 8, but by 9 years, and the result is incorrect.

5. Look for clues in the text that allow you to answer the question using knowledge from the biology course.

Hints for answering the third question:

Mention in the text that the plump is a tit. Tits belong to the order Passeriformes.

Information that plumes hatch their chicks in hollows. All hollow-nesting birds are nestlings, and in nestlings, the young are born naked, blind and helpless. This means that the chubby one has it too.

6. Carefully write down the solution point by point: question number, answer to the question, justification.

Task 30

In this task you are given a table with statistical data. It must be analyzed and answered questions based on knowledge of the biology course.

Example assignment

Using the “Blood Flow Volume” table and knowledge of the biology course, answer the following questions:

1. In which organ does blood flow decrease during physical activity and why?

2. Why does blood flow in the skin increase during physical activity?

3. What part of the vegetative nervous system activated during exercise: sympathetic or parasympathetic?

Blood flow volume:

Solution

1. The table shows that during physical activity, blood flow in the small intestine decreases. To answer the question “why”, we use knowledge of biology. In this case, the reason is the need to ensure greater blood flow to the muscles and skin.

2. The skin provides thermoregulation, protecting against overheating through the release and evaporation of sweat. Sweat requires abundant blood flow through the skin to form.

3. During physical activity, the sympathetic nervous system is activated.

Task 31

This task provides a list of conditions and statistical data on the basis of which you need to select a menu, namely: a table of energy consumption when performing certain actions in kilocalories and a list of products, their calorie content and their content of proteins, fats and carbohydrates.

Example assignment

Masha and Misha decided to visit the climbing wall. To save on bus fare, they put on rollerblades and in half an hour of fast skating they got to the climbing wall, where they spent 2 hours on the climbing slopes, after which they returned home on rollerblades the long way, spending 40 minutes.

At home, Masha and Misha decided to have lunch. Masha is allergic to gluten, which is found in most cereals, and Misha does not like fish, but wants a lot of protein in his diet.

Indicate the energy consumption of Masha and Misha and create a recommended lunch for each, taking into account individual needs.

Table 1

Dishes and drinks	Energy value (kcal)	Proteins (g)	Fat (g)	Carbohydrates (g)
Hercules	303	12,8	6	65,4
Buckwheat	153	5,8	1,7	29,1
Semolina	119	3	5,2	15,4
Oatmeal	115	4,5	5	13,6
Pasta	356	10,9	0,6	74
Millet porridge	131	4,6	1,3	25,9
Boiled rice	123	2,5	0,7	36,1
Boiled potatoes	74	1,7	0,2	15,8
Soup from a bag	333	10,7	3,3	51,6
Instant noodles	326	10	1,1	69
Beef stew (net weight of one can is usually 350 g)	220	16,8	17	0
Sprats in oil (net weight of one can is usually 350 g)	362	17,5	32,3	0
Raw smoked sausage	473	24,8	41,5	0
Cheese	370	26,8	27,4	0
Sweet crackers	377	9	4,6	72,8
Cookie cracker	352	11	13,3	67,1
Sweet cookies	445	7,5	16	68
Bread	235	8	0,9	50
Orange juice	60	0,7	0,1	13,2
Tea without sugar	0	0	0	0

table 2

Algorithm for completing the task

1. Using the table, we calculate energy costs.

Climbing wall - 5.5 kcal/min, 2 hours, that is, 120 minutes.

Roller skating - 7.5 kcal/min, 30 minutes there and 40 minutes back, total 70 minutes.

(5.5×120)+(7.5×70)= 660+525=1185 kcal.

2. Based on the condition, we select products that can be used.

If it is said that Masha cannot have gluten, she must cross out all products that contain it. Gluten is found in cereals, with the exception of buckwheat and rice, so you need to cross out all other cereals, baked goods, pasta and sausage.

If it is indicated that Misha does not like fish, but wants to get more protein, you need to cross out the fish and choose products with the highest protein content.

It is necessary to reason in a similar way if the condition mentions some other circumstances or restrictions.

3. We create a menu in such a way as to cover the resulting number of calories expended. The excess is permissible by no more than 20 kilocalories.

Menu for Masha: soup from a package, potatoes, sprats in oil, cheese, orange juice - 1199 kcal.

Menu for Misha: raw smoked sausage, cheese, crackers, orange juice - 1206 kcal.

Task 32

It is always associated with task 31 and is performed based on the data that you received.

Example assignment

Which young climber will feel fuller longer after lunch at rest? Explain your choice.

Solution

We know that carbohydrates are absorbed faster than fats. Evaluate Masha and Misha's menu in terms of the amount of fat. Masha has 63.3 g of fat on the menu, Misha has 82.3 g, which means Misha will feel full longer.

The OGE in biology is not included in the list of mandatory exams, but is chosen by students quite often. According to experts, the majority of subjects pass the exam in this subject quite successfully, so the subject has gained the reputation of being relatively easy. Also, a number of 9th grade graduates plan to enter medical schools. Biology is also chosen when entering the 10th grade with a certain bias.At the 9th grade stage, there is not much material covered; it is quite easy to understand and master.

In 2018, the minimum threshold was 13 points - in other words, to pass the exam for the minimum score, you need to complete 13 tasks. Maximum – 32 points for an “excellent” rating.
The structure of the biology exam is similar to other exams:

The first part is designed to test the level of knowledge of factual data, laws, and terms. These are ordinary test tasks where you need to find the correct answer from those proposed, establish correspondence, sequence - the answers are displayed in the answer form.
The second part consists of several tasks that require a detailed answer. It is necessary to solve the problem and describe in detail the course of conclusions.

According to the level of complexity, all tasks are divided into three levels of complexity, which allows you to qualitatively assess the student’s preparation and compliance of his knowledge with the norms and standards of the program: basic, in-depth and advanced.

The first step is to decide on the goal that needs to be achieved. Based on the goal, you can create a detailed preparation plan. Without a plan, the process of repeating and studying information will be fragmentary, unsystematic, and the result will not be the best. Familiarization with will allow you to create a plan according to which preparation will be carried out. It is very important to organize yourself so that you do not deviate from the plan, and to study regularly. It's best to combine independent work, attentiveness in class and consultation with a teacher or tutor.
I will solve the OGE in biology - this is additional opportunity assess the level of knowledge, consolidate the theory, get used to working with test tasks of different types and levels of complexity.
Is it possible to prepare from scratch?
Yes. This requires time, self-discipline and the opportunity to consult with a professional. In this case, it is recommended to hire a tutor and regularly complete assignments online.
It is recommended to begin preparation at the beginning of the 9th grade in order to repeat the material from previous years:

General biology;
Anatomy;
Botany;
Ecology;
Zoology.

Taking into account the specifics of your knowledge, allocate time to repeat all of the courses listed.
The advantages of preparing using online testing: the ability to evaluate and consolidate knowledge, saving time, the ability to immediately calculate points for correct answers, you can use the resource at any time, regardless of where you are.

THEORETICAL MATERIAL

BIOLOGY AS A SCIENCE. METHODS OF BIOLOGY

Biology - the science of life, its patterns and forms of manifestation, its existence and distribution in time and space. She explores the origins of life and its essence, development, interconnections and diversity. Biology refers to natural sciences.

The term “biology” was first used by the German professor of anatomy T. Ruz in 1779. However, it became generally accepted in 1802, after the French naturalist J.-B. began to use it in his works. Lamarck.

Modern biology represents complex science, consisting of a number of independent scientific disciplines with their own objects of research.

BIOLOGICAL DISCIPLINES

Botany- plant science,

Zoology- animal science,

Mycology- about mushrooms,

Virology- about viruses,

Microbiology- about bacteria.

Anatomy- the science that studies internal structure organisms (individual organs, tissues). Plant anatomy studies the structure of plants, animal anatomy studies the structure of animals.

Morphology- a science that studies the external structure of organisms

Physiology- a science that studies the vital processes of the body and the functions of individual organs.

Hygiene- the science of preserving and strengthening human health.

Cytology- cell science.

Histology- tissue science.

Taxonomy- the science of classifying living organisms. Classification is the division of organisms into groups (species, genus, families, etc.) based on structural features, origin, development, etc.

Paleontology- a science that studies the fossil remains (imprints, fossils, etc.) of organisms.

Embryology- the science that studies the individual (embryo) development of organisms.

Ecology- a science that studies the relationships of organisms with each other and with environment.

Ethology- the science of animal behavior.

Genetics- the science of the laws of heredity and variability.

Selection- the science of breeding new and improving existing breeds of domestic animals, varieties of cultivated plants and strains of bacteria and fungi.

Evolutionary doctrine- studies issues of origin and laws historical development life on Earth.

Anthropology- the science of the emergence and development of man.

Cell engineering- a branch of science dealing with the production of hybrid cells. An example is the hybridization of cancer cells and lymphocytes, the fusion of protoplasts of different plant cells, and cloning.

Genetic Engineering- a branch of science that deals with the production of hybrid DNA or RNA molecules. If cell engineering works at the cell level, then genetic engineering works at molecular level. In this case, specialists “transplant” the genes of one organism to another. One of the results genetic engineering is the production of genetically modified organisms (GMOs).

Bionics- a direction in science that searches for opportunities to apply the principles of organization, properties and structures of living nature in technical devices.

Biotechnology- a discipline that studies the possibilities of using organisms or biological processes to obtain substances needed by a person. Typically, biotechnological processes use bacteria and fungi.

GENERAL METHODS OF BIOLOGY

A method is a way of understanding reality.

1. Observation and description.

2.Measurement

3. Comparison

4. Experiment or experience

5. Simulation

6. Historical.

STEPS scientific research

Held observation over an object or phenomenon

based on the data obtained, it is put forward hypothesis

scientific experiment(with control experience)

a hypothesis tested during an experiment can be called
theory or by law

PROPERTIES OF LIVING

Metabolism and energy flow- the most important property of living things. All living organisms absorb the substances they need from the external environment and release waste products into it.

Unity chemical composition. Among chemical elements In living organisms, carbon, oxygen, hydrogen and nitrogen predominate. Besides, the most important feature living organisms are present organic matter: fats, carbohydrates, proteins and nucleic acids.

Cellular structure. All organisms are made up of cells. Only viruses have a non-cellular structure, but they also show signs of being alive only after entering the host cell.

Irritability- the body’s ability to respond to external or internal influences.

Self-reproduction. All living organisms are capable of reproduction, that is, the reproduction of their own kind. Reproduction of organisms occurs in accordance with the genetic program recorded in DNA molecules.

Heredity and variability.

Heredity is the ability of organisms to pass on their characteristics to their descendants. Heredity ensures continuity of life. Variability is the ability of organisms to acquire new characteristics in the process of their development. Hereditary variability is an important factor in evolution.

Growth and development.

Growth - quantitative changes (for example, increase in mass).

Development - qualitative changes (for example, the formation of organ systems, flowering and fruiting).

Self-regulation - the ability of organisms to maintain the constancy of their chemical composition and vital processes - homeostasis.

Adaptation

Rhythm - periodic changes in the intensity of physiological functions with different periods fluctuations (daily, seasonal rhythms). (For example, photoperiodism is the body’s response to length daylight hours).
