Some animals, such as birds, have beaks, while other animals, like horses, have large mouths with flat teeth.
The difference in these structures is most closely related to -- 

• the sounds the animals make.
• the habitat the animals live in.
• the type of offspring they have.
• the types of food these animals eat.

The whiskers of a cheetah and the antennae of a beetle are shown in the photographs.

• They help organisms eat food quickly.
• They help organisms defend themselves.
• They help organisms get information about their environment.
