Q. No.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
Unlike a population, an individual has:
| 1. | Birth and death | 2. | Birth rate |
| 3. | Death rate | 4. | Sex ratio |
In a pond, there were 20 lotus plants last year. If through reproduction 4 new lotus plants are added, the number of offspring per lotus per year would be:
| 1. | 0.2 | 2. | 0.4 |
| 3. | 2.0 | 4. | 4.0 |
The given age pyramid represents a:
| 1. | Fast expanding population | 2. | Slowly expanding population |
| 3. | Stable population | 4. | Declining population |
1. Pug marks
2. Cub count
3. Area allocation
4. Collar position
If a new habitat is just being colonized, which of the following is most likely to contribute to an increase in the population density?
| 1. | Birth rate | 2. | Death rate |
| 3. | Immigration | 4. | Emigration |
When population density is plotted against time, the exponential growth curve is:
| 1. | S shaped | 2. | Straight line |
| 3. | J shaped | 4. | Hyperbola |
In the logistic growth equation given below, the carrying capacity is represented by:
\(\frac{\mathrm{dN}}{\mathrm{dt}}=\mathrm{rN}\left(\frac{\mathrm{K}-\mathrm{N}}{\mathrm{K}}\right)\)
| 1. | N | 2. | r |
| 3. | K | 4. | K – N / K |
Darwinian fitness is represented by:
| 1. | Low r value | 2. | High r value |
| 3. | High K value | 4. | Low K value |
Which of the following organisms does not breed only once in their life time?
| 1. | Pacific salmon | 2. | Marsupial mice |
| 3. | Birds | 4. | Bamboo |
