D)Bone strength is more important than body shape in the locomotion of land animals.

Question

Quizplus · Accepted Answer

Locomotion requires overcoming both friction and gravity, as animals have to move against the force of friction generated between their bodies and the surface they are moving on, and also against the downward force of gravity. Both factors are important in locomotion, regardless of whether the animals live on land or in water. Bone strength and body shape may also be important factors, but they are not as universally relevant as overcoming friction and gravity.
