It is much easier for a small animal to run uphill than for a large animal, because
1 The efficiency of muscles in large animals is less than in the small animals
2 it is easier to carry a small body weight
3 Smaller animals have a higher metabolic rate
4 Small animals have a lower $\mathrm{O}_2$ requirement
Explanation:
Small animals have high metabolic rate so they can easily run uphill than for a large animal, metabolism results in release of energy. Hence, smaller animals have more energy and that makes it more easier for them to run uphill than a large animal. Metabolic rate is directly proportional to the size of animal. HindII is the first discovered restriction enzyme by Werner Arber. Smaller animals have higher BMR (Basal metabolic rate) related with sustained energy production and delayed muscles fatigue.

Which two of the following changes $(a-d)$ usually tend to occur in the plain dwellers when they move to high altitudes $(3,500 \mathrm{~m}$ or more)?
1 $(B)$ and $(C)$
2 $(C)$ and $(D)$
3 $(A)$ and $(D)$
4 $(\mathrm{A})$ and $(B)$
Explanation:
The body undergoes numerous changes at higher elevation in order to increase oxygen delivery to cells and improve efficiency of oxygen use. The early changes includes increased breathing rate, increased heart rate and fluid shifts. The later changes includes increased red blood cell production. increased 2, 3 DPG production and increased number of capillaries. The number of red blood cells increases when there is little oxygen because the body is trying to compensate for the lack of oxygen. At high altitude, the lack of oxygen is sensed by carotid bodies, which causes an increases in the breathing depth and rate Then there is an increases in breathing and heart rate to as much as double, even while resting.

Two opposite forces operate in the growth and development of every population. One of them related to the ability to reproduce at a given rate. The force opposite to it is called :
1 Fecundity
2 Environmental resistance
3 Biotic control
4 Mortality
Explanation:
Two opposite forces operate in the growth and development of every population. One of them related to the ability to reproduce at a given rate, the force opposite to it is called environmental resistances. - Environmental resistances is factor that can limit the increase in a population common factors include predators disease, competitors and lack of food, water and suitable habitat, contributed by environmental resistance, as a result overall population of the species does not grow uncontrollably.

What will be happen if the number of organism increased at a place
1 Inter species competition
2 Intra species competition
3 Both
4 None
Explanation:
The number of organism increased at a place of inter species competition and intra species competition. This is generally for food, water, shelter and specifically perfect mate. Intra species competition occurs between members of the same species. Organisms from different species compete for resources called interspecies competition.
