Real questions NTA asked from Animal Kingdom, with the answer and the working. Try before you peek.

Question 1 · NEET 2026

Given below are two statements: Statement I: The class name Reptilia refers to creeping or crawling mode of locomotion. Statement II: All organisms belonging to Reptilia have three chambered heart. In the light of the above statements, choose the most appropriate answer from the options given below:
  1. A.Both Statement I and Statement II are correct
  2. B.Both Statement I and Statement II are incorrect
  3. C.Statement I is correct but Statement II is incorrect
  4. D.Statement I is incorrect but Statement II is correct
Answer and explanation

Answer: C

The class name comes from the Latin repere or reptum, meaning to creep or crawl, so Statement I is correct. Statement II fails on a single well-known exception: CROCODILES have a four-chambered heart, while other reptiles such as lizards, snakes and turtles have three chambers. The word 'all' is what makes the statement false. NCERT Class 11, Animal Kingdom.

Question 2 · NEET 2026

Which of the following is not a characteristic of chordates?
  1. A.Presence of notochord
  2. B.Central nervous system is dorsal
  3. C.Absence of gills
  4. D.Presence of post anal part (tail)
Answer and explanation

Answer: C

Chordates are defined by four fundamental features: a notochord, a dorsal hollow nerve cord, PAIRED PHARYNGEAL GILL SLITS and a post-anal tail. Gill slits are therefore present, not absent - even in terrestrial vertebrates they appear during embryonic development before being modified into other structures. NCERT Class 11, Animal Kingdom.
