In a biosphere reserve, active cooperation with local people is established in the:
| 1. | Natural zone | 2. | Core zone |
| 3. | Buffer zone | 4. | Transition zone |
The most effective means of conservation is to:
1. remove predators
2. preserve habitats
3. vaccinate against diseases
4. census the species during the breeding season
Species most vulnerable to extinction from human activities are those with:
1. low carrying capacities
2. high population growth rates
3. large niches
4. many natural predators
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 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 |

| 1. | South America | 2. | Africa |
| 3. | Europe | 4. | Asia |
Which of the following is not a cause for the loss of biodiversity?
1. Destruction of habitat
2. Invasion by alien species
3. Keeping animals in zoological parks
4. Over-exploitation of natural resources
