The pancreas secretes pancreatic juice containing enzymes like amylase, trypsin, and lipase that help digest carbohydrates, proteins, and fats. Bile juice, produced by the liver and stored in the gall bladder, emulsifies fats into small droplets, making it easier for lipase to act on them for compleRead more

Herbivores like cows and rabbits eat plant food, which is rich in cellulose and hard to digest, so they have a longer small intestine for complete digestion and absorption. Carnivores like tigers and lions eat protein-rich, easily digestible food, so they have a shorter small intestine.

ANSWER: [A] Explanation: Correct option: (a) The near point of his eyes has receded away. The student can clearly see the blackboard but cannot read his textbook, which means he suffers from hypermetropia (farsightedness). In this defect, the near point of the eye shifts farther away than normal, maRead more
ANSWER: [A]
Explanation: Correct option: (a) The near point of his eyes has receded away. The student can clearly see the blackboard but cannot read his textbook, which means he suffers from hypermetropia (farsightedness). In this defect, the near point of the eye shifts farther away than normal, making nearby objects appear blurred.

ANSWER: [C] Explanation: Correct option: (c) 40 cm. To obtain an image of magnification M = − 1, the image must be real, inverted and of the same size as the object. This happens when the object is placed at twice the focal length of a convex lens. The given focal length is f = 20 cm. Hence, the objRead more
ANSWER: [C]
Explanation: Correct option: (c) 40 cm. To obtain an image of magnification M = − 1, the image must be real, inverted and of the same size as the object. This happens when the object is placed at twice the focal length of a convex lens. The given focal length is f = 20 cm. Hence, the object should be placed at 2f = 40 cm. At this position, the image is formed on the opposite side of the lens, also at 40 cm, with the same size as the object but inverted.
