Question

In responding to the force of gravity, which characteristic is present in many land animals?


A. They rely on soft tissues to maintain their shape


B. They must be able to move quickly


C. They have a rigid musculoskeletal system


D. They have wings and flippers

Answer 1

Answer:

C.

Explanation:

Based on the answers provided it can be said that the main response of the force of gravity on land animals is that is caused them to have a rigid musculoskeletal system. This is because the Earth's gravity provides the needed help for land animals to maintain their muscle mass, mainly due to  Earth's pull putting stress on the skeletal system, which helps keep it sturdy and rigid for the animal to be able to move appropriately.
