Try this first
Why do different types of tissues have varying levels of X-ray absorption?.
- A.Due to differences in their temperature.
- B.Due to differences in their density and atomic composition.
- C.Due to differences in their color.
- D.Due to differences in their shape.
Model answer
What a good answer should say
- Due to differences in their density and atomic composition.
Explanation
Why this works
Different tissues have varying densities and atomic structures, which affect how they interact with X-rays. Tissues with higher atomic numbers or greater density absorb more X-rays, resulting in different appearances on the X-ray image.
