Question

how is the skeleton similar to the frame of a house?
○ both are made of calcium.
○ both provide shape and support.
○ both allow movement.
○ both separate the structures into compartments.

Explanation:

• Analyze Option 1: A house frame is not made of calcium, so this is incorrect.
• Analyze Option 2: A skeleton gives the body its shape and supports it; a house frame gives the house its shape and supports the structure. This is a valid similarity.
• Analyze Option 3: A house frame does not allow movement, so this is incorrect.
• Analyze Option 4: A skeleton does not separate the body into compartments like a house frame (if we consider rooms) isn't the main function of a skeleton. So this is incorrect.

Answer:

B. Both provide shape and support.
