Study the marking See what earns credit and compare it with a full-mark answer.
Marking points
- 1 State that X-rays are absorbed by bone.
- 2 State that X-rays can pass through flesh or soft tissue.
Full-mark answer
X-rays are absorbed by bone, but they can pass through flesh, so bones show up in the X-ray image.
Why this answer loses marks
Bones absorb X-rays.
This gains the bone absorption idea but omits that X-rays can pass through flesh.
