Which organelle is responsible for degrading damaged or worn-out cellular components within a cell?
सही उत्तर: ख) Lysosome
The lysosome is the primary degradation compartment of the cell, containing enzymes that break down lipids, carbohydrates, proteins and nucleic acids. The other organelles listed – mitochondria, ribosomes, and the endoplasmic reticulum – have different, distinct functions within the cell.

If a series of days begins with Monday and has a pattern where each day increases by one following the standard days of the week, what will be the 15th term in this series?
सही उत्तर: क) Monday
The series follows the pattern Monday, Tuesday, Wednesday,... The days increase sequentially. Therefore, the 15th term is Friday.

A uniform conducting plate of length l and resistance R is bent into a circle. What is the radius of the circle?
सही उत्तर: ख) lπ
The circumference of the circle is 2πr, where r is the radius. Since the plate is bent into a circle with length l, we have 2πr = l. Therefore, r = l/(2π). The other options are incorrect because they do not reflect this relationship based on the geometry.

A particle moves with a velocity v = (2t + t²) m/s, where 't' is in seconds. What is the displacement of the particle from its initial position after 2 seconds?
सही उत्तर: क) 10 m
Displacement is found by integrating the velocity function with respect to time. ∫v dt = ∫(2t + t²) dt = t² + (t³/3) + C. Since the particle starts at position 0 at t=0, C = 0. Therefore, displacement at t=2s is (2)² + ((2)³/3) = 4 + 8/3 = 12/3 + 8/3 = 20/3 ≈ 6.67m. The closest answer to this value is 6 m.

A long solenoid has 700 turns and a length of 1 meter. If a current of 3 Amperes flows through it, what is the magnetic field strength (in Tesla) at its center?
सही उत्तर: क) 1.5 x 10⁻³ T
The magnetic field strength inside a solenoid is given by B = μ₀nI, where μ₀ (permeability of free space) = 4π × 10⁻⁷ T⋅m/A and n is the number of turns per unit length. In this case, n = 700 turns / 1 m = 700 turns/m and I = 3 A. Therefore, B = (4π × 10⁻⁷ T⋅m/A) * 700 * 3 A = 8.4 x 10⁻³ T. The closest answer is 3.0 x 10⁻³ T, which contains a rounding error.

The process of converting an alcohol to its corresponding alkyl halide using concentrated hydrochloric acid is called:
सही उत्तर: ग) Halogenation
Halogenation, specifically the reaction with HCl, is the standard method for converting alcohols into alkyl halides. Reduction involves adding hydrogen, oxidation involves loss of electrons and esterification involves forming an ester.

The reaction of ethanol with excess HI produces which major product?
सही उत्तर: ग) 1-Iodoethane
Ethyl iodide is the major product formed when primary alcohols react with concentrated hydroiodic acid. The other options are either products of competing reactions or involve different reagents.

What number comes next in this series: 1, 4, 9, 16, 25, ?
सही उत्तर: क) 30
The series consists of perfect squares (1^2, 2^2, 3^2, 4^2, 5^2...). Therefore, the next term is 6^2 = 36.

A and B are standing facing each other. A is to the east of B. C is to the north of A. D is to the west of B. E is directly south of C. If a line is drawn from A to E, what direction does this line point?
सही उत्तर: घ) South-East
The arrangement describes the spatial relations: A is east of B, C is north of A, D is west of B, and E is south of C. This creates a square - forming a North West direction when connecting A to E.
