10 of the 180 questions, with answers and explanations. The rest are in the app.
Question 1
Biology · Cell: The Unit of LifeThe prokaryotic ribosomes have the sedimentation coefficient of:
- A 40S
- B 80S, composed of 60S and 40S subunits
- C 70S, composed of 50S and 30S subunits
- D 60S
Answer: C. 70S, composed of 50S and 30S subunits
Why: The eukaryotic ribosomes are 80S.
Question 2
Biology · Biotechnology and Its ApplicationsWhich of the following is NOT a benefit of genetically modified crops?
- A It always increases the nutritional value of the crop
- B it helps to reduce post-harvest losses
- C it reduces the use of chemical pesticides
- D it increases the tolerance to abiotic stresses
Answer: A. It always increases the nutritional value of the crop
Why: Nutritional enhancement applies only to specifically designed crops such as golden rice.
Question 3
Biology · Strategies for Enhancement in Food ProductionPusa Gaurav is a variety of Brassica that is resistant to:
- A drought
- B fungus
- C salt
- D the aphids
Answer: D. the aphids
Why: The flat pod in okra resists the shoot and fruit borer.
Question 4
Biology · Environmental IssuesVermicomposting uses earthworms to convert organic kitchen and farm waste into:
- A toxic sludge
- B nutrient-rich compost that improves soil fertility
- C biogas only
- D plastic-free packaging
Answer: B. nutrient-rich compost that improves soil fertility
Why: Earthworms ingest organic waste and excrete nutrient-rich castings, producing compost that improves soil structure and fertility while reducing landfill waste.
Question 5
Biology · Plant KingdomThe protonema in the mosses is:
- A the capsule
- B the sporophyte
- C the creeping, green, branched and frequently filamentous stage developed directly from the spore
- D the male gametophore
Answer: C. the creeping, green, branched and frequently filamentous stage developed directly from the spore
Why: The second stage is the leafy stage.
Question 6
Physics · Motion in a PlaneThe vertical component of a force of 10 N acting at 30° above the horizontal is:
- A 10 N
- B 2.5 N
- C 5 N
- D 8.66 N
Answer: C. 5 N
Why: F sin30° = 10 × 0.5 = 5 N.
Question 7
Physics · Electromagnetic InductionA spark appears at a switch when a circuit containing a large inductor is suddenly opened because:
- A a large emf is induced in the inductor as the current falls rapidly
- B the capacitor discharges
- C the resistance is zero
- D the battery voltage doubles
Answer: A. a large emf is induced in the inductor as the current falls rapidly
Why: ε = L dI/dt is large when dI/dt is large.
Question 8
Chemistry · Environmental ChemistryWhich of the following is a primary pollutant?
- A ozone in smog
- B H₂SO₄ in acid rain
- C PAN
- D SO₂
Answer: D. SO₂
Why: A primary pollutant is released directly into the air.
Question 9
Chemistry · AminesThe Gabriel phthalimide synthesis is used to prepare:
- A aromatic primary amines
- B secondary amines
- C tertiary amines
- D pure primary aliphatic amines
Answer: D. pure primary aliphatic amines
Why: Aryl halides do not undergo the nucleophilic substitution step, so the method works only for aliphatic primary amines.
Question 10
Chemistry · HydrogenLiquid hydrogen is used as a rocket fuel because it:
- A is easy to store at room temperature
- B is heavier than air
- C has a very high energy per unit mass on combustion
- D is non-flammable
Answer: C. has a very high energy per unit mass on combustion
Why: The product is just water.
