10 of the 180 questions, with answers and explanations. The rest are in the app.
Question 1
Biology · Digestion and AbsorptionInflammation of the intestinal tract is the most common ailment due to the bacterial or viral infections and is called:
- A jaundice
- B constipation
- C indigestion
- D gastroenteritis
Answer: D. gastroenteritis
Why: The cause may be the intestinal worms.
Question 2
Biology · Animal KingdomWhich of the following has an open circulatory system?
- A chordates
- B echinoderms
- C annelids
- D arthropods and molluscs
Answer: D. arthropods and molluscs
Why: The blood pumped by the heart passes through the open-ended vessels into the cavities (sinuses).
Question 3
Biology · Locomotion and MovementThe pivot joint is found between the:
- A atlas and axis
- B the femur and the hip bone
- C the carpals
- D the humerus and scapula
Answer: A. atlas and axis
Why: It allows the rotation of the head.
Question 4
Biology · Breathing and Exchange of GasesInspiration (inhalation) occurs when the diaphragm:
- A relaxes and moves upward, decreasing thoracic volume
- B contracts and moves downward, increasing thoracic volume
- C stays fixed while ribs move down
- D contracts and moves upward
Answer: B. contracts and moves downward, increasing thoracic volume
Why: Contraction of the diaphragm flattens it and moves it downward, expanding the thoracic cavity and lowering intrapulmonary pressure below atmospheric, drawing air in.
Question 5
Biology · Strategies for Enhancement in Food ProductionSemi-dwarf, high-yielding wheat varieties that triggered the Green Revolution in India were developed by introducing genes for dwarfing from a variety bred by:
- A Norman Borlaug in Mexico
- B Gregor Mendel in Austria
- C Charles Darwin in England
- D Hugo de Vries in Holland
Answer: A. Norman Borlaug in Mexico
Why: Norman Borlaug developed semi-dwarf, high-yielding, disease-resistant wheat varieties in Mexico, which India adapted from the mid-1960s to dramatically raise wheat production.
Question 6
Physics · Ray Optics and Optical InstrumentsThe resolving power of a telescope is increased by:
- A increasing the diameter of the objective
- B using red light only
- C decreasing the diameter of the objective
- D using a longer-focus eyepiece
Answer: A. increasing the diameter of the objective
Why: Resolving power ∝ D/λ; larger apertures see finer detail and collect more light.
Question 7
Physics · Thermal Properties of MatterThe rate of heat flow through a metal rod is H. If its length is doubled keeping everything else the same, the rate becomes:
- A 4H
- B H/4
- C H/2
- D 2H
Answer: C. H/2
Why: H = KA ΔT/L, so the rate is inversely proportional to the length.
Question 8
Chemistry · Coordination CompoundsGold is extracted from its ores by dissolving it in aqueous cyanide solution as:
- A Au²⁺
- B Au(CN)₃
- C [Au(CN)₂]⁻
- D AuCN₂ gas
Answer: C. [Au(CN)₂]⁻
Why: The complex is then reduced with zinc.
Question 9
Chemistry · ThermodynamicsUsing bond enthalpies H–H = 436, Cl–Cl = 243 and H–Cl = 431 kJ/mol, the enthalpy change for H₂ + Cl₂ → 2HCl is:
- A +183 kJ
- B −183 kJ
- C −862 kJ
- D +679 kJ
Answer: B. −183 kJ
Why: ΔH = (436 + 243) − 2 × 431 = 679 − 862 = −183 kJ.
Question 10
Chemistry · Redox EquilibriumThe oxidation number of carbon in CH₂Cl₂ is:
- A 0
- B +4
- C +2
- D −2
Answer: A. 0
Why: x + 2(+1) + 2(−1) = 0.
