Q. No.Keoladeo National Park, host to migratory birds from Siberia, is in:
1.
Rajasthan
2.
Uttar Pradesh
3.
Madhya Pradesh
4.
Gujarat
In animals, the organism, if unable to migrate, might avoid the stress by escaping in time. All the following would exemplify this except:
| 1. | Hibernation | 2. | Aestivation |
| 3. | Diapause | 4. | Migration |
Under unfavorable conditions, many zooplankton species in lakes and ponds are known to enter a stage of suspended development called as:
| 1. | Dormancy | 2. | Hibernation |
| 3. | Aestivation | 4. | Diapause |
Any attribute of the organism that enables the organism to survive and reproduce in its habitat is called as:
1. Adaptation
2. Phenotypic plasticity
3. Acclimatization
4. Norm of the reaction
All the following are adaptations in desert plants to minimize water loss except:
1. Thick cuticle
2. photosynthesis
3. CAM pathway
4. Sunken stomata
According to Allen’s rule:
| 1. | Mammals from colder climates generally have shorter appendages |
| 2. | Mammals from colder climates generally have longer appendages |
| 3. | Mammals from colder climates generally have smaller body size |
| 4. | Mammals from colder climates generally have larger body size |
A thick layer of fat, blubber, beneath the skin is found in:
1. Terrestrial mammals of colder climates
2. Aquatic mammals of colder climates
3. Terrestrial mammals of warmer climates
4. Aquatic mammals of warmer climates
High altitude acclimatization in humans include all the following except:
| 1. | Increased RBC production |
| 2. | Increased breathing rate |
| 3. | Increased heart rate |
| 4. | Increased binding affinity of haemoglobin |
For the purpose of ecological studies, the term population is applicable to individuals reproducing:
| 1. | Asexually | 2. | Sexually |
| 3. | Both 1 and 2 | 4. | Neither 1 nor 2 |
Unlike a population, an individual has:
| 1. | Birth and death | 2. | Birth rate |
| 3. | Death rate | 4. | Sex ratio |
