Answer key and explanations.

Use this section after completing all 50 questions. Each correct answer includes a brief explanation to help you revise the underlying concept that will be helpful for your exam.

Physics explanations for the MCQs Practice Test

1. C — 12 m/s. Use \(v=u+at=0+(2\times6)=12\text{ m/s}\).

2. B — 3 A. Ohm’s law gives \(I=V/R=12/4=3\text{ A}\).

3. A — 5 m. Maximum height is \(H=u^2\sin^2\theta/(2g)\). Substituting gives \(400\times0.25/20=5\text{ m}\).

4. D — Isochoric. An isochoric process occurs at constant volume.

5. B — +5 D. Lens power \(P=1/f\), with focal length in metres. Therefore, \(P=1/0.20=+5\text{ D}\).

6. C — 1/8. Twelve hours represent three half-lives. The remaining fraction is \((1/2)^3=1/8\).

7. C — 2 m. Wavelength \(\lambda=v/f=340/170=2\text{ m}\).

8. D — 6 μF. For parallel capacitors, capacitances add: \(C=2+4=6\text{ μF}\).

9. C — 50 J. Work \(W=Fs\cos\theta=10\times5\times1=50\text{ J}\).

10. A — Maximum kinetic energy increases. The maximum kinetic energy is \(K_{\max}=hf-\phi\). Increasing the frequency above the threshold increases the electron kinetic energy when the work function is unchanged.

Chemistry explanations

11. B — 0.5 mol. Number of moles \(=22/44=0.5\text{ mol}\).

12. C — pH 4. Assuming complete ionization, \([H^+]=10^{-4}\text{ M}\), so pH \(=-\log_{10}[H^+]=4\).

13. D — Fluorine. Fluorine has the highest electronegativity on the Pauling scale.

14. C — +6. Let sulfur’s oxidation number be \(x\): \(2(+1)+x+4(-2)=0\). Therefore, \(x=+6\).

15. B — Covalent bond. Covalent bonding involves sharing electron pairs between atoms.

16. A — Shifts towards ammonia. The product side contains two moles of gas, compared with four moles on the reactant side. Higher pressure favours the side with fewer gaseous moles.

17. A — Tollens’ reagent. Many aldehydes reduce Tollens’ reagent to metallic silver, forming a silver mirror.

18. B — sp². Each carbon in ethene forms three sigma bonds and participates in a pi bond, consistent with sp² hybridization.

19. C — Benzene. Benzene is a cyclic, conjugated aromatic compound with six delocalized pi electrons.

20. C — 0.4 M. Molarity \(=0.2/0.5=0.4\text{ mol/L}\).

Zoology explanations

21. B — Nephron. The nephron is the structural and functional unit of the kidney.

22. C — Insulin. Insulin promotes glucose uptake and storage, helping lower blood glucose.

23. D — Cerebellum. The cerebellum coordinates movement, posture, and balance.

24. C — Red blood cells. Haemoglobin in red blood cells carries most oxygen in the blood.

25. A — Plasma cells. Activated B lymphocytes can differentiate into plasma cells, which secrete antibodies.

26. B — Meiosis. Meiosis reduces chromosome number by half and produces haploid cells used in sexual reproduction.

27. C — Plasmodium species. Protozoan parasites of the genus Plasmodium cause malaria.

28. D — Pulmonary vein. Pulmonary veins carry oxygenated blood from the lungs to the left atrium.

29. C — Alveoli. Thin alveolar walls and surrounding capillaries facilitate oxygen and carbon dioxide exchange.

30. B — 1/4. The cross Aa × Aa produces a 1 AA : 2 Aa : 1 aa genotype ratio. Only aa shows the recessive phenotype.

Botany explanations

31. C — Chloroplast. Chloroplasts contain chlorophyll and are the main sites of photosynthesis.

32. B — Xylem. Xylem transports water and mineral ions from roots towards the shoots.

33. D — Auxin. Auxin promotes cell elongation in suitable tissues and contributes to apical dominance.

34. B — Gas exchange and regulation of water loss. Stomata allow carbon dioxide entry and oxygen and water vapour exchange; guard cells regulate their opening.

35. C — Mitosis. Mitosis produces daughter cells with the same chromosome number as the parent cell and supports growth and repair.

36. B — Phloem. Phloem transports sugars and other organic substances from sources to sinks.

37. C — Ovule. After fertilization, the ovule typically develops into a seed, while the ovary develops into the fruit.

38. B — Rhizobium. Rhizobium bacteria form associations with legume roots and fix atmospheric nitrogen.

39. C — Pyramid of energy. Usable energy decreases at successive trophic levels, making the energy pyramid upright.

40. D — Gymnosperms. Gymnosperms produce exposed or “naked” seeds that are not enclosed in an ovary-derived fruit.

Mental Agility Test explanations

41. C — 42. The differences are 4, 6, 8, and 10. The next difference is 12, giving \(30+12=42\).

42. B — All doctors are educated. If every doctor is a graduate and every graduate is educated, all doctors must be educated.

43. C — 80%. Percentage correct \(=(40/50)\times100=80\%\).

44. D — Cube. A cube is three-dimensional, while a square, triangle, and circle are two-dimensional plane figures.

45. A — EPH. Each letter advances by one position: D → E, O → P, and G → H.

46. B — 5 km. The route forms a right triangle, so displacement \(=\sqrt{3^2+4^2}=5\text{ km}\).

47. C — Eating. A book is used for reading, just as a fork is used for eating.

48. B — 5 minutes. Each machine produces one item in five minutes. Ten machines working simultaneously can produce ten items in the same five minutes.

49. C — U. The letter positions increase by 2, 3, 4, and 5. The next increase is 6: O → U.

50. C — 90°. At 3:00, the minute hand points to 12 and the hour hand points to 3. The smaller angle is 90°.

How to calculate your practice score

For this practice session that uses the standard MEC marking System of +1 for a correct response and −0.25 for an incorrect response, use:

[ \text{Score}=\text{Correct}-0.25(\text{Incorrect}) \]

Unanswered questions receive zero in this calculation.

For example, if you answer 40 questions correctly, 6 incorrectly, and left 4 unanswered:

[ 40-(6\times0.25)=38.5 \]

Your Practice exam score for this MECEE Mock test would be 38.5 out of 50. This is a raw practice score, not an official MECEE-BL percentile or admission prediction.

Preparation tips for MECEE-BL

These are the preparation tips for the MBBS entrance questionsin Nepal. They will help you focus on what you are preparing now.
