Sample DIM Bakalavr Group IV Practice Questions

Try these sample questions to test your DIM Bakalavr Group IV exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which cellular organelle is responsible for aerobic cellular respiration and ATP generation through oxidative phosphorylation?
A.Mitochondria
B.Ribosome
C.Golgi apparatus
D.Lysosome
Explanation: Mitochondria are the double-membraned powerhouses of eukaryotic cells. They house the citric acid (Krebs) cycle within their matrix and the electron transport chain on their inner folded cristae, generating the majority of cellular ATP via oxidative phosphorylation.
2According to Chargaff's rules of DNA base pairing, if a double-stranded DNA molecule contains 28% adenine (A), what is the percentage of cytosine (C)?
A.22%
B.28%
C.44%
D.56%
Explanation: In double-stranded DNA, adenine pairs with thymine (%A = %T = 28%), totaling %A + %T = 56%. The remaining base pairs are guanine and cytosine: %G + %C = 100% - 56% = 44%. Because %G = %C, the percentage of cytosine is 44% / 2 = 22%.
3Which chamber of the human heart has the thickest muscular myocardium and pumps oxygenated blood into the systemic aorta under high pressure?
A.Left ventricle
B.Right ventricle
C.Left atrium
D.Right atrium
Explanation: The left ventricle possesses the thickest muscular wall of all four heart chambers because it must generate enough systolic pressure (approx. 120 mmHg) to pump oxygenated blood throughout the entire systemic circulatory system via the aorta.
4Which hormone, secreted by the beta cells of the islets of Langerhans in the pancreas, promotes glucose uptake into cells and stimulates glycogen synthesis in the liver?
A.Insulin
B.Glucagon
C.Cortisol
D.Thyroxine
Explanation: Insulin is a peptide hormone produced by pancreatic beta cells in response to elevated blood glucose levels. It promotes GLUT-4 transporter translocation, cellular glucose uptake, glycolysis, and glycogenesis in liver and skeletal muscle cells.
5In a monohybrid cross between two heterozygous pea plants with yellow seeds (Aa x Aa, where yellow A is dominant to green a), what is the expected phenotypic ratio among the offspring?
A.3 yellow : 1 green
B.1 yellow : 2 green : 1 yellow
C.1 yellow : 1 green
D.All yellow
Explanation: A monohybrid cross between two heterozygotes (Aa x Aa) produces genotypes 1 AA : 2 Aa : 1 aa. Because both AA and Aa produce the dominant yellow phenotype, the phenotypic ratio is 3 yellow : 1 green (75% yellow, 25% green).
6During which phase of Meiosis I does crossing-over (homologous genetic recombination) occur between non-sister chromatids?
A.Prophase I (Pachytene stage)
B.Metaphase I
C.Anaphase I
D.Telophase I
Explanation: Crossing-over occurs during Prophase I of Meiosis I (specifically during the pachytene substage of synapsis), where non-sister chromatids of homologous chromosome pairs exchange genetic segments at chiasmata.
7During the light-dependent reactions of oxygenic photosynthesis in the thylakoid membranes of chloroplasts, what is the primary source of the released oxygen (O2) gas?
A.Photolysis of water molecules (H2O)
B.Splitting of carbon dioxide (CO2)
C.Degradation of glucose
D.Reduction of NADP+
Explanation: Oxygen released during photosynthesis comes directly from the photolysis (water splitting) of H2O at the oxygen-evolving complex of Photosystem II: 2 H2O -> 4 H^+ + 4 e^- + O2. (Cornelis van Niel and Ruben-Kamen isotopic experiments proved O2 originates from water, not CO2).
8What is the structural and functional microscopic filtration unit of the human kidney?
A.Nephron
B.Neuron
C.Alveolus
D.Hepatocyte
Explanation: The nephron is the functional microscopic unit of the kidney (each human kidney contains approx. 1 to 1.2 million nephrons), consisting of a renal corpuscle (Bowman's capsule and glomerulus) and a renal tubule (PCT, loop of Henle, DCT).
9Which of the following characteristics distinguishes insects (Class Insecta) from arachnids (Class Arachnida)?
A.Insects have 3 pairs of walking legs and a 3-part body (head, thorax, abdomen)
B.Insects have 4 pairs of walking legs and book lungs
C.Insects have an open circulatory system while arachnids have closed
D.Insects lack an exoskeleton
Explanation: Adult insects are characterized by a 3-segmented body (head, thorax, abdomen), 3 pairs of jointed thoracic walking legs (6 legs), and usually 1-2 pairs of wings. Arachnids (spiders, scorpions) have 2 body parts (cephalothorax and abdomen) and 4 pairs of walking legs (8 legs) with no antennae or wings.
10According to Lindeman's ecological efficiency rule (10% law), approximately what percentage of energy is transferred from one trophic level to the next consecutive higher trophic level in a food chain?
A.Approximately 10%
B.Approximately 50%
C.Approximately 90%
D.Approximately 1%
Explanation: Lindeman's 10% rule of trophic efficiency states that on average, only about 10% of the energy stored as biomass in one trophic level is transferred to the next higher level; the remaining 90% is lost as metabolic heat, respiration, and unassimilated waste.
