Model answer
What a good answer should say
- Bones absorb more X-rays than soft tissues.
Explanation
Why this works
Bones have a higher density and atomic number compared to soft tissues, which means they absorb more X-rays. This greater absorption results in a lighter appearance (white) on the X-ray image, while softer tissues appear darker.
