In a group of 5 people, A is taller than B, C is shorter than D, and E is taller than F. If we arrange them from tallest to shortest, who will be in the middle?
सही उत्तर: क) A
We are given: A > B, C < D, E > F. Combining this, we get E > A > B > C and E > F > C . Since there are 5 people, arranging them from tallest to shortest means order is E, A, D, B, C. Therefore, the person in the middle is D.

The process of autophagy involves the degradation and recycling of damaged cellular components. Which organelle plays a central role in this process? (A) Endoplasmic Reticulum (B) Golgi Apparatus (C) Lysosome (D) Peroxisome
सही उत्तर: ग) Lysosome
Lysosomes contain enzymes that break down cellular waste products and damaged organelles – this is the core function of autophagy. The other organelles have distinct roles in protein synthesis and modification.

Which of the following is a key characteristic distinguishing prokaryotic cells from eukaryotic cells? (A) Presence of membrane-bound organelles. (B) Containment of DNA within a nucleus. (C) Smaller size compared to eukaryotic cells. (D) Ribosomes are present in both types of cells.
सही उत्तर: ख) Containment of DNA within a nucleus.
Eukaryotic cells possess complex internal structures like the nucleus and mitochondria, enclosed by membranes. Prokaryotic cells lack these membrane-bound organelles, and their DNA is not contained within a nucleus.

Which of the following cellular structures is primarily responsible for maintaining cell volume by regulating the movement of water in and out of the cell? (A) Ribosomes (B) Mitochondria (C) Cell Membrane (Plasma Membrane) (D) Nucleus
सही उत्तर: ग) Cell Membrane (Plasma Membrane)
The cell membrane’s phospholipid bilayer and associated proteins control the passage of water molecules into and out of the cell through osmosis. Ribosomes are involved in protein synthesis, mitochondria produce energy, and the nucleus contains genetic material.

The process of oogenesis (formation of female gametes) is initiated during which phase of the menstrual cycle? (A) Menstruation (B) Follicular Phase (C) Ovulation (D) Luteal Phase
सही उत्तर: ग) Ovulation
Oogenesis begins during the follicular phase when primordial follicles develop into primary oocytes. Menstruation marks the end of a cycle, ovulation releases the mature egg, and the luteal phase follows ovulation.

Which of the following statements best describes the function of cilia in respiratory epithelium? (A) They facilitate gas exchange between air and blood. (B) They propel mucus and trapped particles towards the pharynx for removal. (C) They provide structural support to the epithelial cells. (D) They enhance nutrient absorption from the inhaled air.
सही उत्तर: ख) They propel mucus and trapped particles towards the pharynx for removal.
Cilia are tiny hair-like structures that beat in a coordinated manner to move mucus and debris across the surface of the respiratory tract. Option A is incorrect as gas exchange occurs at alveoli, not cilia. Option C describes cell shape, and option D is incorrect regarding nutrient absorption.

If A + B means A is the father of B, A − B means A is the wife of B, and A × B means A is the brother of B, find the result of 2 × 3
सही उत्तर: ख) B
According to the given rules, 2 × 3 means '2 is the brother of 3'. Therefore, the answer is B.

A uniform wire of length L is stretched until its diameter becomes D. If the Young's modulus for the material is Y, then the stress applied will be:
सही उत्तर: क) (a) LY/D
Stress is defined as force per unit area. In this case, the force applied is the stress, and the area is the cross-sectional area of the wire (πr² = π(D/2)²). So, Stress = Force / Area = Y * (D/2) / (D/2) = Y. Thus, it should be LY/D.

The refractive index of a glass is 1.5 for light traveling in the direction of incidence and 1.3 for light travelling perpendicular to the direction of incidence. Calculate the ordinary and extraordinary refractive indices.
सही उत्तर: क) (a) Ordinary = 1.5, Extraordinary = 1.3
The ordinary refractive index (n₀) is the refractive index for light traveling perpendicular to the direction of incidence. The extraordinary refractive index (nₛ) is the refractive index for light traveling parallel to the direction of incidence. Given nᵢ = 1.5 and n⊥ = 1.3, we can find n₀ = 1.3 and nₛ = 1.5.

A particle moving with velocity 'v' makes an angle θ with the normal to the plane of motion. The horizontal component of velocity is 2 m/s and the vertical component is 3 m/s, then what is the magnitude of the velocity?
सही उत्तर: क) (a) 3.5 m/s
The horizontal and vertical components of velocity are perpendicular to each other. Using the Pythagorean theorem, we can calculate the magnitude of the velocity: v = √( (2)² + (3)²) = √13 ≈ 3.6 m/s. The closest answer is (a) 3.5m/s.
