Question

analogies are often used to help make concepts easier to understand. trisha wants to write an analogy to help her remember the difference between the axial skeleton and the appendicular skeleton. which is the best analogy?

the axial skeleton is like the skin of an apple; the appendicular skeleton is like the core of an apple.

the axial skeleton is like the core of an apple; the appendicular skeleton is like the skin of an apple.

the axial skeleton is like the frame of a swing set; the appendicular skeleton is like the swings.

the axial skeleton is like the swings on a swing set; the appendicular skeleton is like the frame of a swing set.

Explanation:

To determine the best analogy, we recall the functions of the axial and appendicular skeletons. The axial skeleton (skull, spine, ribcage) forms the central core and structural support of the body. The appendicular skeleton (limbs, shoulder/hip girdles) is attached to the axial skeleton and enables movement (like swings attached to a swing - set frame).

• For the apple - related options: The axial skeleton is the core (central support), not the skin, so options with axial as skin or appendicular as core are incorrect.
• For the swing - set options: The axial skeleton is the frame (central support), and the appendicular skeleton is the swings (attached and for movement), which matches their functions.

Answer:

C. The axial skeleton is like the frame of a swing set; the appendicular skeleton is like the swings.
