Question 2
Phenylketonuria is an inborn error of metabolism that is inherited as:
- A an autosomal recessive trait, in which phenylalanine accumulates and is converted to phenylpyruvic acid
- B a Y-linked trait
- C an X-linked dominant trait
- D a chromosomal aberration
Answer: A. an autosomal recessive trait, in which phenylalanine accumulates and is converted to phenylpyruvic acid
Why: It causes mental retardation if untreated.
Question 3
Robert Brown discovered the:
- A ribosome
- B Golgi body
- C cell wall
- D nucleus
Answer: D. nucleus
Why: He described it in 1831.
Question 4
The rigid fungal cell wall is composed mainly of:
- A peptidoglycan
- B chitin and polysaccharides
- C lignin
- D cellulose
Answer: B. chitin and polysaccharides
Why: The fungi are heterotrophic.
Question 5
In grasshoppers, the male is XO and the female is XX. This type of sex determination is called:
- A XY type
- B ZW type
- C XO type
- D haplodiploidy
Answer: C. XO type
Why: All eggs have an X chromosome, and half of the sperm have an X while half have none.
Question 6
The Earth's magnetic field at a place is 4 × 10⁻⁵ T with a dip of 60°. The horizontal component is:
- A 3.46 × 10⁻⁵ T
- B 8 × 10⁻⁵ T
- C 2 × 10⁻⁵ T
- D 4 × 10⁻⁵ T
Answer: C. 2 × 10⁻⁵ T
Why: H = B cosδ = 4 × 10⁻⁵ × 0.5 = 2 × 10⁻⁵ T.
Question 7
When two waves overlap, the resultant displacement at any point is the algebraic sum of the individual displacements. This is the principle of:
- A superposition
- B reflection
- C conservation of energy
- D refraction
Answer: A. superposition
Why: Waves pass through each other unchanged.
Question 8
In a Daniell cell, the anode and the cathode are respectively:
- A zinc and copper
- B zinc and zinc
- C copper and copper
- D copper and zinc
Answer: A. zinc and copper
Why: Zinc is oxidised at the anode and Cu²⁺ is reduced at the cathode.
Question 9
The adsorption of a gas on a solid surface increases with:
- A an increase in the temperature
- B a decrease in the pressure of the gas
- C a decrease in the surface area of the solid
- D an increase in the pressure of the gas
Answer: D. an increase in the pressure of the gas
Why: More gas molecules strike the surface at higher pressure, so more are adsorbed.
Question 10
Cleansing action of soap depends on the formation of:
- A a crystalline lattice
- B micelles that trap grease in their hydrocarbon interior
- C a covalent bond with dirt
- D an insoluble precipitate
Answer: B. micelles that trap grease in their hydrocarbon interior
Why: Above the critical micelle concentration, soap molecules aggregate with hydrocarbon tails inward and polar heads outward. Grease dissolves in the tails and the whole micelle is washed away in water.
