Sample questions from Mock 18 with answers

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

Question 1

Biology · Reproductive Health

Artificial insemination (AI) involves:

  1. A tying the oviducts
  2. B injecting hormones only
  3. C removing the ovary
  4. D introducing the semen of the husband or a donor into the vagina or the uterus (IUI)

Answer: D. introducing the semen of the husband or a donor into the vagina or the uterus (IUI)

Why: It helps where the male cannot inseminate the female.

Question 2

Biology · Human Reproduction

Ovulation, the release of a mature ovum from the ovary, typically occurs around which day of a standard 28-day menstrual cycle?

  1. A day 1
  2. B day 14
  3. C day 21
  4. D day 28

Answer: B. day 14

Why: Ovulation typically occurs around day 14 of a standard 28-day menstrual cycle, roughly midway through the cycle, triggered by a surge in LH.

Question 3

Biology · Animal Kingdom

The Echinoderms have an endoskeleton of:

  1. A chitin
  2. B calcareous ossicles, with the spiny skin
  3. C the bone
  4. D cartilage

Answer: B. calcareous ossicles, with the spiny skin

Why: The adults are radially symmetrical, whereas the larvae are bilaterally symmetrical.

Question 4

Biology · Microbes in Human Welfare

Streptokinase, a 'clot buster' used in patients with a myocardial infarction, is produced by:

  1. A the bacterium Lactobacillus
  2. B the fungus Trichoderma
  3. C the bacterium Streptococcus
  4. D the fungus Monascus purpureus

Answer: C. the bacterium Streptococcus

Why: It dissolves clots in blood vessels.

Question 5

Biology · Excretory Products and Their Elimination

The vasa recta is absent or reduced in:

  1. A none
  2. B all the nephrons
  3. C the juxtamedullary nephrons
  4. D the cortical nephrons

Answer: D. the cortical nephrons

Why: The vasa recta is well developed in the juxtamedullary nephrons.

Question 6

Physics · Electromagnetic Induction

Two coils have self-inductances of 4 H and 9 H, with perfect coupling. Their mutual inductance is:

  1. A 36 H
  2. B 13 H
  3. C 2.25 H
  4. D 6 H

Answer: D. 6 H

Why: M = k√(L₁L₂) = √36 = 6 H for k = 1.

Question 7

Physics · Work, Energy and Power

The potential energy of a particle at a stable equilibrium position is:

  1. A a maximum
  2. B a minimum
  3. C constant along the path
  4. D zero always

Answer: B. a minimum

Why: The force F = −dU/dx is zero there, and any small displacement raises the energy.

Question 8

Chemistry · Structure of Atom

The maximum number of electrons that can be accommodated in the M shell (n=3) is:

  1. A 8
  2. B 18
  3. C 32
  4. D 2

Answer: B. 18

Why: The maximum number of electrons in a shell is given by 2n²; for n=3 (M shell), this is 2×9 = 18.

Question 9

Chemistry · Alcohols, Phenols and Ethers

Alcohols can be prepared from alkenes by acid-catalyzed hydration, which follows:

  1. A Markovnikov's rule
  2. B anti-Markovnikov's rule
  3. C Zaitsev's rule only
  4. D no particular regiochemical rule

Answer: A. Markovnikov's rule

Why: Acid-catalyzed hydration of alkenes proceeds via a carbocation intermediate, following Markovnikov's rule — the -OH group ends up on the more substituted carbon.

Question 10

Chemistry · Some Basic Concepts of Chemistry

The molality of a solution containing 18 g of glucose (molar mass 180 g/mol) dissolved in 500 g of water is:

  1. A 0.2 m
  2. B 0.1 m
  3. C 2 m
  4. D 0.036 m

Answer: A. 0.2 m

Why: 0.1 mol/0.5 kg.
