Glycolysis takes place in the: a) Mitochondria. b) Golgi apparatus. c) Cytoplasm. d) Nucleus.
सही उत्तर: ग) c) Cytoplasm.
Glycolysis (C) is the process of glucose breakdown that occurs in the cytoplasm of cells. Options A & B describe locations where oxidative phosphorylation takes place; option D incorrectly places this process within the nucleus.

A plant cell placed in pure water becomes fully turgid. At this stage: a) The cytoplasm shrinks. b) The vacuole contracts. c) The osmotic pressure is at its maximum. d) The starch granules disappear.
सही उत्तर: ग) c) The osmotic pressure is at its maximum.
The correct answer (C) is accurate because turgidity in plant cells results from the influx of water due to osmosis, increasing the osmotic pressure within the cell. Option A is incorrect as turgor pressure actually *increases* cell volume and rigidity. Option B is false because it describes the opposite process. Option D is irrelevant to the state of turgidity.

A light bulb emits light at an average wavelength of 400 nm. What is the energy of a single photon emitted by the bulb? (h=6.626 x 10⁻³⁴ Js, c=3 x 10⁸ m/s)
सही उत्तर: क) 3.98 x 10⁻¹⁹ J
We can use the equation E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. Plugging in the values: E = (6.626 x 10⁻³⁴ Js * 3 x 10⁸ m/s) / 400 x 10⁻⁹ m = 3.98 x 10⁻¹⁹ J.

A uniform rod of length 1 meter is placed symmetrically on a frictionless horizontal surface. The rod has a mass of 2 kg. What is the magnitude of the frictional force exerted by the surface on the rod?
सही उत्तर: ग) 3 N
Since the rod is uniform, its center of mass is at its midpoint. The net force acting on the system will cause it to rotate about this point. To prevent rotation (equilibrium), a frictional force must be applied in the opposite direction to the torque created by the weight of the rod. The torque due to gravity is 0.5 kg * 9.8 m/s² = 4.9 N·m. The friction force needed to balance this torque is therefore 4.9 N.

A metal rod of length L and cross-sectional area A is heated through a temperature difference ΔT. The rise in thermal energy (heat) absorbed by the rod is given by:
सही उत्तर: ख) ΔT * L * A
The heat gained (Q) is calculated using the formula Q = mcΔT, where m is mass, c is specific heat capacity, and ΔT is the temperature change. However, we're given length and area. The energy absorbed is proportional to the product of ΔT, A, and L because heat transfer through conduction depends on these factors.

A stone of mass 0.5 kg is thrown upwards with an initial velocity of 10 m/s. Taking g = 9.8 m/s², calculate the maximum height reached by the stone (approximate value).
सही उत्तर: ख) 30.6 m
We can use kinematic equations to solve this. At max height, v = 0. Using v² = u² + 2as (where v=0, u=10m/s, a=-9.8m/s², and s is the displacement), we find s = (10)² / (2 * -9.8) = 30.6 meters.

A particle moves along a straight line with accelerating force F. At time t=0, its velocity is zero and displacement is zero. Which of the following statements about the particle’s motion is correct?
सही उत्तर: ख) The particle's velocity remains constant at zero
Newton’s Second Law states F = ma. Since F is constant and the mass ‘m’ is constant, the acceleration ‘a’ must also be constant to maintain a uniform acceleration. The other options are incorrect as they don't reflect this fundamental principle.

A man invests some amount in a bank at the rate of 6% per annum compound interest for 2 years. If the amount after 2 years is Rs 3300, what was the original investment?
सही उत्तर: ख) Rs 3200
Let P be the principal amount. The formula for compound interest is: A = P(1 + r/100)^n, where A is the final amount, r is the rate of interest, and n is the number of years. In this case, A = 3300, r = 6, and n = 2. So, 3300 = P(1 + 6/100)^2 => 3300 = P(1.06)^2 => 3300 = P * 1.1236 => P = 3300 / 1.1236 ≈ Rs 3000.

In a code, ‘APPLE’ is written as 121314 and ‘BANANA’ is written as 14151617. What is ‘GRAPE’?
सही उत्तर: क) 18192021
Each letter in the original word corresponds to a number based on its position in the alphabet. A=1, B=2, C=3, and so on. APPLE (1 16 16 12 5) becomes 121314. BANANA (2 14 1 14 16 17) is represented as 14151617. Therefore, GRAPE (7 18 1 16 5) translates to 18192021.

The presence of a coelom in animals indicates which evolutionary characteristic? (a) A simple body plan with minimal tissue organization (b) The development of a true circulatory system (c) The evolution of greater internal complexity and organ systems (d) A dependence on external respiration for energy production
सही उत्तर: घ) (d) A dependence on external respiration for energy production
A coelom is a fluid-filled body cavity that provides space for organs, allowing for greater structural complexity and efficient movement. This reflects a significant evolutionary step in animal development. (a) describes a simple organism; (b) relates to circulatory systems; (d) refers to respiration.
