NEET2016BotanyBiomolecules (B)Actual
It is much easier for a small animal to run uphill than for a large animal, because:
Options
- AIt is easier to carry a small body weight.
- BSmaller animals have a higher metabolic rate.
- CSmall animals have a lower O 2 requirement
- DThe efficiency of muscles in large animals is less than in the small animals.
Correct answer
B. Smaller animals have a higher metabolic rate.
Step-by-step solution
Smaller animals have higher BMR related to sustained energy production and delayed muscle fatigue. BMR is the rate of energy expenditure per unit time by endothermic animals at rest.
