The reaction of acetone with sodium hydroxide solution followed by treatment with hydrochloric acid produces which product?
सही उत्तर: घ) Acetaldehyde
This is a classic example of the Williamson ether synthesis. Sodium hydroxide deprotonates acetone to form an enolate ion. This enolate then reacts with HCl to form ethyl methyl ketone. The other options represent different reaction pathways involving ketones or aldehydes.

The process of transpiration in plants primarily serves which function? A. To absorb carbon dioxide from the atmosphere. B. To regulate plant temperature by cooling the leaf surface. C. To synthesize proteins within the plant cells. D. To attract pollinators to the flower.
सही उत्तर: ख) To regulate plant temperature by cooling the leaf surface
Transpiration, the loss of water vapor through stomata, generates a pulling force (transpirational gradient) that drives water uptake from the soil. Options A and D describe other functions of transpiration or related processes.

The process by which plants synthesize their own food from sunlight, carbon dioxide, and water is called: A. Transpiration B. Respiration C. Photosynthesis D. Germination
सही उत्तर: ग) Photosynthesis
Photosynthesis is the fundamental process by which plants convert light energy into chemical energy in the form of glucose. Options A, B, and D represent other biological processes – transpiration (water loss), respiration (energy breakdown), and germination (seed sprouting) respectively - that are not the primary food production mechanism.

Which of the following accurately describes the role of the operculum in bony fishes? (a) It is a sensory organ responsible for detecting vibrations in the water. (b) It protects the gills and helps regulate their opening and closing. (c) It primarily functions as a digestive gland, secreting enzymes into the mouth. (d) It is involved in respiration, absorbing oxygen directly from the atmosphere.
सही उत्तर: ख) It protects the gills and helps regulate their opening and closing.
The operculum’s primary function is to protect the delicate gills and play a crucial role in regulating their opening and closing – controlling water flow across the gills for gas exchange. Options (a), (c) and (d) represent incorrect functions of this anatomical feature.
