1. In most healthy vertebrates, which of the following body components has the greatest mass?
Carbohydrates b)) Proteins c) Lipids d) Minerals e) Nucleic acids 2. The energy content of
carbohydrate, protein, and fat isandkcals per gram, respectively a) 1, 3, 5 b) 1, 5, 10 4,4, 9 5, 10,
20 10, 20, 30 e) 3. Common feeding modes in animals include: a) b) -c) attack of individual prey
items. suspension feeding. association with symbiotic microbes d) Both a and c All of the above
4. As an animal increases its rate of powered movement (e.g. increases running speed), its
metabolic rate: calina -(aincreases decreases , stays the same. d) decreases first and then
increases. mass specil:o -e) None of the above; metabolic rate is not correlated with speed. 5.
Which of the following organisms have the lowest mass-specific cost of transport? a) Crow b)
Salmon -c) Sparrow d) Cheetah e) Humarn
Solution
1) b proteins are building block of the body.
2)c, fats gives 9kcal per gram whereas other two gives 4
3)e, All three are feeding modes
4)a, increase because of more requirements of the energy.
5) e human. Larger animals have lesser mass specific cost of transport
