Conservation Of Biodiversity

Ex situ conservation refers to the conservation of components of biological diversity outside their natural habitats. It involves the preservation of plants, animals, and other organisms outside their natural habitats to save them from extinction.

1. Cryopreservation of Gametes: This is an advanced ex situ conservation technique where gametes (sperm and eggs) are stored at low temperatures to maintain their viability over time.
2. Plant Tissue Culture Method: This is a method of culturing plant cells, tissues, or organs under sterile conditions on a nutrient culture medium. It is used to produce large numbers of plants and preserve genetic material.
3. Seed Bank: Seed banks are collections of seeds stored to preserve genetic diversity. Seeds from these banks can be used to grow plants if their natural populations are threatened or destroyed.
4. In Vitro Fertilization (IVF): This is a technique of fertilizing an egg with sperm in a laboratory setting. It is a part of advanced conservation techniques for endangered species.

The correct option is i,ii,iii,iv as all mentioned techniques are part of advanced ex situ conservation strategies. Each method helps in the conservation of genetic material or species itself, ensuring biodiversity is maintained and species are preserved for future generations.

To solve the given matching question, we need to understand the meaning of the terms provided in Column I and match them with the appropriate descriptions in Column II.

1. Narrowly utilitarian argument: This argument emphasizes the specific, tangible benefits that humans derive from biodiversity, such as food, medicine, and industrial products. Therefore, the correct match is with r "Receiving benefits like food, medicine & industrial products."
2. Broadly utilitarian argument: This argument includes the broader benefits of biodiversity that support life, such as ecosystem services like pollination, water purification, and climate regulation. This can be matched with p "Conserving biodiversity for major ecosystem services."
3. Ethical argument: This argument is centered on the intrinsic value of all species and the moral responsibility we have to preserve them for future generations. Hence, this aligns with q "Every species has an intrinsic value and moral duty to pass our biological legacy in good order to future generation."

Based on the explanation above, the correct matching of the columns is: 1-(r), 2-(p), 3-(q).

The right choice among the options provided is 1-(r) 2-(p) 3-(q).
