1Which biological science studies the structure, function, and life processes of cells?

A.Histology

B.Cytology

C.Anatomy

D.Ecology

Explanation: Cytology (цитология) is the branch of biology dedicated to the study of cells, including their organelles, structure, division, and metabolism. It is a core block of the EGE Biology codifier.

2Which research method involves observing biological objects under controlled conditions where the experimenter deliberately changes one factor?

A.Observation

B.Experiment

C.Description

D.Comparison

Explanation: The experimental method involves deliberately manipulating a variable under controlled conditions to test a hypothesis, distinguishing it from passive observation. EGE Biology tests scientific methodology as part of the first content block.

3According to the levels of organization of life, which level is immediately above the cellular level?

A.Molecular level

B.Organism level

C.Population level

D.Tissue level

Explanation: The standard hierarchy of biological organization rises molecular to cellular to tissue to organ to organism to population to ecosystem to biosphere. The tissue level sits directly above the cellular level. This hierarchy is a foundational EGE topic.

4Which property of living systems describes the maintenance of a relatively constant internal environment?

A.Homeostasis

B.Irritability

C.Metabolism

D.Reproduction

Explanation: Homeostasis is the ability of an organism to maintain a stable internal environment (temperature, pH, ion concentrations) despite external changes. It is a defining property of all living systems.

5Which scientist formulated the binomial nomenclature system used to name species with two Latin names?

A.Charles Darwin

B.Gregor Mendel

C.Carl Linnaeus

D.Louis Pasteur

Explanation: Carl Linnaeus introduced binomial nomenclature, giving each species a two-part Latin name (genus and species), such as Homo sapiens. This system is the basis of modern taxonomy tested on the EGE.

6A testable, preliminary explanation proposed to account for an observation is called a:

A.Law

B.Theory

C.Hypothesis

D.Fact

Explanation: A hypothesis is a tentative, testable explanation that can be supported or rejected by experiment. After repeated confirmation, a hypothesis may become part of a scientific theory.

7Which monosaccharide is the primary energy substrate for cellular respiration in most cells?

A.Glucose

B.Sucrose

C.Cellulose

D.Glycogen

Explanation: Glucose (C6H12O6) is a six-carbon monosaccharide and the main immediate energy source oxidized during cellular respiration to produce ATP. The EGE biomolecules block tests carbohydrate structure and function.

8Which organelle is the site of the Krebs cycle and oxidative phosphorylation in eukaryotic cells?

A.Ribosome

B.Chloroplast

C.Mitochondrion

D.Golgi apparatus

Explanation: The mitochondrion is the site of aerobic respiration: the Krebs (citric acid) cycle occurs in the matrix and oxidative phosphorylation occurs on the inner membrane (cristae), producing most of the cell's ATP.

9Which statement correctly distinguishes prokaryotic from eukaryotic cells?

A.Prokaryotes lack a membrane-bound nucleus and membrane organelles

B.Prokaryotes have a membrane-bound nucleus; eukaryotes do not

C.Eukaryotes lack ribosomes; prokaryotes have them

D.Prokaryotes are always larger than eukaryotes

Explanation: Prokaryotic cells (bacteria, archaea) lack a membrane-bound nucleus and membrane-bound organelles; their DNA lies free in the cytoplasm as a nucleoid. Eukaryotic cells have a true nucleus and organelles.

10What is the main function of enzymes (ferments) in biochemical reactions?

A.They increase the activation energy needed

B.They change the equilibrium constant of a reaction

C.They are consumed and destroyed during each reaction

D.They lower the activation energy and speed up reactions

Explanation: Enzymes are biological catalysts (usually proteins) that lower the activation energy of a reaction, dramatically increasing its rate without being consumed. They are highly specific to their substrates.

About the EGE Biology Exam

The EGE (Edinyi Gosudarstvennyi Ekzamen) in Biology is an elective Unified State Exam in Russia, administered by Rosobrnadzor with content developed by FIPI. The 2026 paper has 28 tasks split into two parts: Part 1 contains 21 short-answer tasks of basic and advanced difficulty, and Part 2 contains 7 extended free-response tasks, including genetics problems, worth a maximum of 57 primary points. Results are converted to a 100-point test scale, with 36 test points the minimum threshold set by Rosobrnadzor. The exam covers seven content blocks from biology as a science and cytology to genetics, the diversity of life, human anatomy and physiology, evolution, and ecology. It is taken mainly by students applying to medical, biological, veterinary, and agricultural university programs.

EGE Biology Study Tips from Top Performers

1Study the official FIPI codifier and specification to know exactly which topics and task types appear on the exam.

2Master genetics problems (tasks 27-28): practice monohybrid, dihybrid, and sex-linked crosses until ratios become automatic.

3Learn cytology and metabolism in depth, including photosynthesis, respiration, and the stages of mitosis and meiosis.

4Practice picture-analysis and matching tasks, since Part 1 includes diagram-based questions on cells, organs, and organisms.

5Memorize human organ systems and homeostasis mechanisms, a heavily weighted block emphasized in the 2026 specification.

6Solve full past papers under timed conditions to build the stamina needed for the 235-minute exam.
