Try this first
Why do different tissues absorb X-rays differently?.
- A.Due to variations in tissue density and atomic composition
- B.Because all tissues absorb X-rays equally
- C.Only fat tissues absorb X-rays effectively
- D.X-rays do not interact with tissues
Model answer
What a good answer should say
- Due to variations in tissue density and atomic composition
Explanation
Why this works
Different tissues have varying densities and atomic compositions, which affect their ability to absorb X-rays. Denser tissues, like bone, absorb more X-rays than less dense tissues, such as muscle or fat.
