The process of converting ammonia into nitric acid on an industrial scale is known as:
सही उत्तर: ग) Contact Process
The Contact Process involves the oxidation of ammonia over a platinum catalyst to produce nitric oxide (NO), which then further oxidizes to form nitrogen dioxide (NO₂) and ultimately nitric acid. The other processes deal with different chemicals or industrial methods.

What is the primary reason why sulfuric acid (H₂SO₄) is a strong oxidizing agent?
सही उत्तर: ख) It readily loses electrons.
Option 1 is correct because H₂SO₄ is a strong oxidizing agent due to its ability to accept electrons (lose hydrogen ions) and facilitate redox reactions. The other options describe properties of the substance but do not explain why it's an oxidizing agent.

-
Which of the following compounds will exhibit isomerism?
सही उत्तर: घ) CO₂
CO2 (carbon dioxide) has two structural isomers: linear and bent. The other options do not have the same number of atoms for each element, so they cannot form isomeric forms. Nitrogen gas(NH₃) is a linear molecule as it only requires one rotation to form its shape whereas methane (CH₄) has no rotational freedom.

The decomposition of potassium chlorate (KClO₃) can be represented as: 4KClO₃(s) → 3KClO₄(s) + KCl(s). Which statement accurately describes this reaction?
सही उत्तर: ख) The reaction is endothermic and releases heat.
Option 1 is correct because the formation of KClO₄ is an endothermic process, requiring energy input. The other options are incorrect; KCl is a solid not a precipitate in this scenario and the reaction doesn't involve a stable gaseous product (it produces a different potassium salt).

Among five friends, P is taller than Q, R is shorter than S, T is taller than P and S is shorter tha
सही उत्तर: ख) Q
We are given that P > Q, S < R, T > P, and S < R. Combining these inequalities logically, we have T > P > Q and R > S. Since the question asks for the *odd one out*, this is related to a sequence of relationships—the relationship 'shorter than' is the critical factor because it’s consistently used.”},{

Which of the following best describes the role of ‘synapses’ in neuronal communication?
सही उत्तर: घ) The area of the neuron responsible for receiving incoming signals
Synapses are specialized junctions that allow neurons to communicate through the release of neurotransmitters. The space between neurons is crucial for chemical transmission, not direct electrical contact. Neurotransmitter synthesis occurs within the neuron itself.

-
Which of the following cell types is primarily responsible for initiating the inflammatory response upon tissue injury?
सही उत्तर: ग) Erythrocytes
Neutrophils, a type of white blood cell, are the first responders to inflammation. They migrate to sites of infection or injury and release chemicals that attract other immune cells. Lymphocytes activate adaptive immunity, while erythrocytes carry oxygen and osteoclasts resorb bone.

-
The phenomenon of ‘positive feedback’ is most prominently observed during which physiological process?
सही उत्तर: ख) Regulation of blood glucose levels
Positive feedback loops, like those involved in the menstrual cycle, amplify a signal. During menstruation, oxytocin release stimulates uterine contractions, which further stimulate oxytocin production – a self-reinforcing cycle. Blood clotting and digestion of fats involve negative feedback loops.

-
The process of parturition (childbirth) is stimulated by an increase in the levels of which hormone during pregnancy?
सही उत्तर: ग) Oxytocin
Oxytocin, produced by the pituitary gland, plays a crucial role in triggering uterine contractions and promoting labor. Estrogen and progesterone are primarily involved in maintaining early pregnancy, while testosterone is a male sex hormone.

The characteristic olive-green to brown color of brown algae (Phaeophyceae) is primarily due to the presence of: (A) Chlorophyll a and chlorophyll c (B) Carotenoids, specifically fucoxanthin (C) Phycoerythrin pigments (D) Anthocyanins
सही उत्तर: ग) (C) Phycoerythrin pigments
Brown algae contain significant amounts of fucoxanthin, a carotenoid pigment that absorbs blue-green light and reflects green and brown wavelengths, resulting in the characteristic color. Options (A) and (C) describe other pigments found in different algal groups.
