Question 2
The flower that can be divided into two equal halves in any radial plane is:
- A actinomorphic, e.g. mustard, datura and chilli
- B bilateral
- C zygomorphic
- D asymmetric
Answer: A. actinomorphic, e.g. mustard, datura and chilli
Why: The zygomorphic flower can be divided into two equal halves in only one plane, e.g. the pea.
Question 3
Double fertilization, a process unique to angiosperms among seed plants, is NOT found in:
- A gymnosperms
- B dicot angiosperms
- C monocot angiosperms
- D all flowering plants
Answer: A. gymnosperms
Why: Double fertilization, producing both a zygote and a nutritive triploid endosperm, is a defining and unique feature of angiosperms; gymnosperms do not undergo this process.
Question 4
In the logistic growth model, the growth rate is greatest when the population size is about:
- A zero
- B K/2
- C 2K
- D K
Answer: B. K/2
Why: At K, the growth rate becomes zero.
Question 5
The hormone which stimulates the gall bladder to release the bile is:
- A secretin
- B cholecystokinin (CCK)
- C insulin
- D gastrin
Answer: B. cholecystokinin (CCK)
Why: CCK also stimulates the release of the pancreatic enzymes.
Question 6
The number of molecules per cubic metre of a gas at 300 K and 10⁵ Pa is about (k = 1.38 × 10⁻²³ J/K):
- A 2.4 × 10²³
- B 6 × 10²³
- C 2.4 × 10²⁸
- D 2.4 × 10²⁵
Answer: D. 2.4 × 10²⁵
Why: n = P/kT = 10⁵/(1.38 × 10⁻²³ × 300) ≈ 2.4 × 10²⁵ m⁻³.
Question 7
If the speed of a vehicle is doubled, with the same braking retardation, the stopping distance becomes:
- A eight times
- B two times
- C half
- D four times
Answer: D. four times
Why: s = u²/2a ∝ u².
Question 8
Sodium benzoate and salts of sorbic acid are used as:
- A artificial sweeteners
- B food preservatives
- C flavours
- D antioxidants
Answer: B. food preservatives
Why: They prevent the growth of microorganisms.
Question 9
The number of electrons in one mole of water molecules is:
- A 6.022 × 10²³
- B 1.2 × 10²⁴
- C 6.022 × 10²⁴
- D 6.022 × 10²⁵
Answer: C. 6.022 × 10²⁴
Why: Each water molecule has 10 electrons.
Question 10
The IUPAC name of CH₃COCH₃ is:
- A ethanone
- B propanone
- C propan-2-ol
- D propanal
Answer: B. propanone
Why: A three-carbon chain with a ketone group (suffix -one).
