Which of the following accurately describes the function of the notochord in chordates?
सही उत्तर: ख) B. It provides skeletal support and serves as a primitive backbone.
The notochord is a flexible rod located along the dorsal side of chordates; it provides structural support during development and acts as a temporary skeletal framework, laying the groundwork for the future vertebral column – options A, C and D describe other functions.

The process of exocytosis, where vesicles fuse with the plasma membrane, is most closely associated with which of the following cellular activities?
सही उत्तर: ग) C. Osmosis – movement of water across a semi-permeable membrane.
Exocytosis is the process by which cells release substances outside of themselves via vesicle fusion with the plasma membrane, primarily for secretion. Phagocytosis involves engulfment, osmosis concerns water movement, and mitosis is a cell division process; thus they are incorrect choices.

Consider the series: 2, 4, 8, 16, ?
सही उत्तर: ख) 32
This is a standard geometric progression where each number is doubled to get the next. Therefore, the answer is 32.

If ‘RED’ is called ‘BLUE’, ‘BLUE’ is called ‘GREEN’, and ‘GREEN’ is called ‘YELLOW’, what is ‘YELLOW’ called?
सही उत्तर: क) PINK
This is a simple substitution cipher. Each color is replaced by another based on the given rule. Therefore, YELLOW is correctly identified as ORANGE.

Which of the following structures is responsible for nutrient transport within a plant?
सही उत्तर: ख) Xylem
The phloem is the vascular tissue that transports sugars and other organic nutrients throughout the plant, from source to sink. Xylem transports water and minerals. The cuticle protects the leaf, and the epidermis covers the entire plant surface.

The process of photosynthesis involves light-dependent reactions which produce ATP and NADPH. Which plant hormone primarily regulates the opening and closing of stomata to balance carbon dioxide uptake and water loss?
सही उत्तर: ग) Abscisic Acid
Abscisic acid (ABA) is a key regulator of stomatal closure, responding to drought stress. The other hormones have different primary roles in plant development – auxin promotes cell elongation, cytokinins stimulate cell division, and gibberellins influence stem growth.

Which of the following plant groups exhibits alternative phyllotaxy?
सही उत्तर: ग) Ferns
Alternative phyllotaxy means leaves are arranged in an alternating pattern around the stem. Dicots, like many flowering plants, typically exhibit this arrangement. Monocots have spiral phyllotaxy, ferns show multiple arrangements and bryophytes lack a true stem for leaf arrangement.

The potential energy U of a system of two charges q₁ and q₂ separated by a distance r is given by U = k q₁q₂ / r, where k is Coulomb’s constant. If q₁ = +3 μC, q₂ = -4 μC, and r = 0.5 m, what is the potential energy? (k = 9 × 10⁹ N⋅m²/C²)
सही उत्तर: ख) 3.6×10^8 J
The potential energy U is calculated using the formula U = k q₁q₂ / r. Substituting the given values, we get U = (9 × 10⁹ N⋅m²/C²) * (3 × 10⁻⁶ C) * (-4 × 10⁻⁶ C) / (0.5 m) = -2.16 × 10⁻⁵ J. However, the question is incorrectly posed and has a numerical error requiring an approximate solution to arrive at one of the provided answers. The closest answer is 2.7×10^8 J.
