Sample questions from Mock 15 with answers

10 of the 180 questions, with answers and explanations. The rest are in the app.

Question 1

Biology · Human Reproduction

The middle piece of a sperm contains numerous mitochondria, which:

  1. A carry the genes
  2. B form the zona pellucida
  3. C provide energy for the movement of the tail
  4. D contain the hydrolytic enzymes

Answer: C. provide energy for the movement of the tail

Why: The tail enables swimming.

Question 2

Biology · Anatomy of Flowering Plants

Simple permanent tissues in plants, such as parenchyma, collenchyma, and sclerenchyma, are composed of:

  1. A cells of a single type performing the same function
  2. B multiple different cell types
  3. C only dead cells
  4. D only meristematic cells

Answer: A. cells of a single type performing the same function

Why: Simple permanent tissues consist of only one type of cell that work together to perform the same function, unlike complex tissues (xylem, phloem), which contain multiple cell types.

Question 3

Biology · Environmental Issues

Increased UV-B radiation reaching the Earth after ozone depletion can cause:

  1. A snow-blindness, cataract and skin cancer
  2. B eutrophication
  3. C rise in sea level only
  4. D acid rain

Answer: A. snow-blindness, cataract and skin cancer

Why: UV-B damages DNA and inflames the cornea.

Question 4

Biology · Biotechnology and Its Applications

A single-stranded DNA or RNA, tagged with a radioactive molecule (a probe), is allowed to hybridise to its complementary DNA in a clone of cells. The cells where it hybridises are detected by:

  1. A a chromatography
  2. B microscopy only
  3. C a centrifugation
  4. D autoradiography

Answer: D. autoradiography

Why: The clone with the mutated gene will not appear on the photographic film.

Question 5

Biology · Human Health and Diseases

Malaria is caused by a parasite belonging to the genus:

  1. A Plasmodium
  2. B Escherichia
  3. C Mycobacterium
  4. D Entamoeba

Answer: A. Plasmodium

Why: Malaria is caused by protozoan parasites of the genus Plasmodium, transmitted through the bite of an infected female Anopheles mosquito.

Question 6

Physics · Ray Optics and Optical Instruments

The power of a lens is measured in diopters and is defined as:

  1. A the reciprocal of the focal length in meters
  2. B the focal length in meters
  3. C the square of the focal length
  4. D the product of focal length and refractive index

Answer: A. the reciprocal of the focal length in meters

Why: Power P = 1/f (in meters), measured in diopters (D); a converging lens has positive power, a diverging lens negative.

Question 7

Physics · Work, Energy and Power

Which of the following is a conservative force?

  1. A Friction
  2. B Gravitational force
  3. C Air resistance
  4. D Viscous drag

Answer: B. Gravitational force

Why: Gravitational force is conservative — the work it does depends only on initial and final positions, not the path taken; friction, air resistance and viscous drag are all non-conservative (dissipative) forces.

Question 8

Chemistry · Electrochemistry

The time needed to deposit 0.3175 g of copper (M = 63.5) by a current of 1 A (F = 96500 C/mol) is:

  1. A 965 s
  2. B 96.5 s
  3. C 9650 s
  4. D 1930 s

Answer: A. 965 s

Why: 0.3175 g is 0.005 mol, which needs 0.01 mol of electrons = 965 C.

Question 9

Chemistry · Aldehydes, Ketones and Carboxylic Acids

A Grignard reagent reacts with carbon dioxide, followed by hydrolysis, to give:

  1. A an aldehyde
  2. B a carboxylic acid
  3. C an alcohol
  4. D a ketone

Answer: B. a carboxylic acid

Why: RMgX + CO₂ → RCOOMgX → RCOOH.

Question 10

Chemistry · States of Matter

At the same temperature and pressure, equal volumes of all gases contain the same number of molecules. This is:

  1. A Boyle's law
  2. B Avogadro's law
  3. C Charles' law
  4. D Graham's law

Answer: B. Avogadro's law

Why: Avogadro's law relates the volume of a gas to the number of moles at constant T and P.
