Which statement about locomotion is true?
A) Locomotion requires energy to overcome friction and gravity.
B) Gravity is a greater locomotion problem for animals in water than for those on land.
C) Overcoming friction is a greater locomotion problem for land animals than for those that live in water.
D) Bone strength is more important than body shape in the locomotion of land animals.

Question

Quizplus · Accepted Answer

Locomotion, regardless of the environment, requires energy to overcome the opposing forces of friction and gravity. This is because friction and gravity create resistance to the motion of the animal, which requires energy to overcome. Therefore, statement A is the one that is true. B is false because water provides buoyancy that helps animals overcome gravity. C is false because water is more viscous than air, which creates more friction and drag making it a greater locomotion problem for aquatic animals. D is false because body shape is just as important as bone strength in locomotion for land animals as it helps them distribute their weight and balance their bodies.
