MCQ
Which blood cells of frogs are nucleated?
  • A. RBCs
  • B. WBCs
  • C. Platelets
  • D. All of the above
✅ Correct Answer: A
Unlike mammals, frogs have nucleated RBCs.
Assertion-Reason
Assertion (A): Male and female frogs can be distinguished by external features. Reason (R): Female frogs have vocal sacs and copulatory pads on their fore limbs.
  • A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
  • B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
  • C. If assertion is true but reason is false.
  • D. If the assertion and reason both are false.
✅ Correct Answer: C
NCERT states “Male frogs can be distinguished by the presence of sound producing vocal sacs and also a copulatory pad on the first digit of the fore limbs which are absent in female frogs.” The Assertion is true - males and females can be distinguished externally. However, the Reason is false. NCERT explicitly states these features are present in “male frogs” and “absent in female frogs,” not the reverse.
NEET 2025 Pattern
Match the basic tissue types found in animals given in Column I with their characteristic features given in Column II and their primary roles given in Column III. Column I (Tissue Type) A. Epithelial tissue B. Connective tissue C. Muscular tissue D. Neural tissue Column II (Characteristic Feature) 1. Composed of elongated contractile fibres 2. Exerts the greatest control over the body’s responsiveness 3. Cells are tightly packed with little intercellular matrix 4. Most abundant and widely distributed tissue in the body Column III (Primary Role) I. Binding and supporting other tissues and organs II. Providing covering and forming protective barriers III. Movement and locomotion IV. Rapid transmission of impulses through excitable cells Choose the correct option:
  • A. A-3-II, B-4-I, C-1-III, D-2-IV
  • B. A-4-II, B-3-I, C-1-III, D-2-IV
  • C. A-3-I, B-4-II, C-1-III, D-2-IV
  • D. A-1-III, B-2-I, C-3-II, D-4-IV
✅ Correct Answer: A
Let's match the tissue types, their characteristic features, and primary roles as described in the NCERT chapter 'Structural Organisation in Animals': A. Epithelial Tissue: Characterized by 'cells are compactly packed with little intercellular matrix' (from subsequent section). Its primary role is to 'provide a covering or a lining for some part of the body. They also form a barrier'. So, A matches with 3 and II. B. Connective Tissue: This tissue type is 'most abundant and widely distributed in the body of complex animals'. Its 'special function of linking and supporting other tissues/organs of the body'. So, B matches with 4 and I. C. Muscular Tissue: Each muscle is 'made of many long, cylindrical, parallelly arranged fibres'. Its key function is 'contraction and relaxation' for movement. So, C matches with 1 and III. D. Neural Tissue: 'Neural tissue exerts the greatest control over the body’s responsiveness to changing conditions... neurons, the unit of neural system are excitable cells... transmit stimuli very rapidly'. So, D matches with 2 and IV. Therefore, the correct sequence of matching is A-3-II, B-4-I, C-1-III, D-2-IV.
