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

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.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
