2. Indo-Burma
3. Himalayas
4. Deccan plateau
What percent of earth’s area is covered by hotspots of biodiversity?
| 1. | less than 2 | 2. | about 7 |
| 3. | about 11 | 4. | more than 16 |
According to your NCERT text, the number of biosphere reserves, national parks and wildlife sanctuary in India are respectively:
| 1. | 14, 90 and 448 | 2. | 11, 98 and 440 |
| 3. | 15, 101 and 403 | 4. | 13, 92 and 427 |
1. Seed bank
2. National park
3. Cryopreservation
4. Botanical garden
If the threat of extinction is high, the preferred strategy for the conservation of this threatened species would be:
| 1. | In-situ conservation | 2. | Ex-situ conservation |
| 3. | Either of the two | 4. | Neither of the two |
Agricultural biodiversity is conserved:
1. in ex-situ locations commonly in the form of gene banks
2. in ex-situ locations commonly in botanical gardens
3. in in-situ locations such as biosphere reserves
4. in in-situ locations in agricultural institute fields
The agricultural practice of producing or growing a single crop, plant or livestock species, variety, or breed in a field or farming system at a time is called as:
1. Monoculture
2. Polyculture
3. Oligoculture
4. Agriculture
The reasons to store seeds in a seed bank include all except:
| 1. | To have available the genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, taste, etc. of crops. |
| 2. | To forestall loss of genetic diversity in rare plant species in an effort to conserve biodiversity ex-situ. |
| 3. | To preserve the historical and cultural value of plants not grown now. |
| 4. | To guard against biopiracy by limiting the use of seeds only in certain areas. |
Recalcitrant seeds are:
1. seeds that do not survive drying and freezing during ex-situ conservation
2. seeds that can resist the effects of drying or temperatures less than 10 °C
3. can be stored for long periods
4. terminator seeds
Freezable specimens that can be preserved with cryopreservation include all except:
| 1. | Semen | 2. | Seeds |
| 3. | Early embryos | 4. | Human heart |
