Question 1 · NEET 2025

Match List-I with List-II. List-I List-II A. The Evil Quartet I. Cryopreservation B. Ex situ conservation II. Alien species invasion C. Lantana camara III. Causes of biodiversity losses D. Dodo IV. Extinction Choose the option with all correct matches.

  1. A.A-III, B-II, C-I, D-IV
  2. B.A-III, B-I, C-II, D-IV
  3. C.A-III, B-IV, C-II, D-I
  4. D.A-III, B-II, C-IV, D-I
Show answer

Answer: B. A-III, B-I, C-II, D-IV

The Evil Quartet refers to causes of biodiversity losses (A-III). Ex situ conservation includes cryopreservation (B-I). Lantana camara is an alien invasive species (C-II). Dodo is an extinct bird (D-IV).

Question 2 · NEET 2024

The regions with high level of species richness, high degree of endemism and a loss of 70% of the species and habitat are identified as:

  1. A.Natural Reserves
  2. B.Sacred Groves
  3. C.Biodiversity Hotspots
  4. D.Biogeographical Regions
Show answer

Answer: C. Biodiversity Hotspots

The question describes regions with high species richness, high endemism, and a 70% loss of original habitat. These criteria match the definition of 'Biodiversity Hotspots' as defined by Conservation International.

Question 3 · NEET 2024

Match List-I with List-II: List-I List-II A. Biodiversity hotspot I. Khasi and Jantia hills in Meghalaya B. Sacred groves II. World Summit on Sustainable Development 2002 C. Johannesburg, South Africa III. Parthenium D. Alien species invasion IV. Western Ghats Choose the correct answer from the options given below:

  1. A.A-IV, B-I, C-II, D-III
  2. B.A-II, B-III, C-IV, D-I
  3. C.A-I, B-IV, C-III, D-II
  4. D.A-III, B-I, C-II, D-IV
Show answer

Answer: A. A-IV, B-I, C-II, D-III

Biodiversity hotspot: Western Ghats (A-IV). Sacred groves: Khasi hills example (B-I). Johannesburg 2002: WSSD (C-II). Alien species invasion: Parthenium is a classic example (D-III).

Question 4 · NEET 2024

Cryopreservation technique is used for:

  1. A.Protection of environment
  2. B.Protection of Biodiversity hotspots
  3. C.Preservation of gametes in viable and fertile condition for a long period
  4. D.In-situ conservation
Show answer

Answer: C. Preservation of gametes in viable and fertile condition for a long period

Cryopreservation involves freezing biological materials (like gametes, embryos) at very low temperatures, preserving them viable and fertile for extended periods, commonly used in IVF, seed banks.

Question 5 · NEET 2024

Which one of the following is not included under in-situ conservation?

  1. A.Wild-life sanctuary
  2. B.Botanical garden
  3. C.Biosphere reserve
  4. D.National park
Show answer

Answer: B. Botanical garden

In-situ conservation involves protecting species in their natural habitats. Wild-life sanctuaries, biosphere reserves, and national parks are all in-situ methods. Botanical gardens are ex-situ conservation sites where plants are maintained outside their natural habitat.
