Answer:

Explanation:
First, let's figure out what heparin is.
It is a prescription, injectable drug that is a blood thinner. It helps to prevent the blood from clotting.
Now, let's analyze each disease and see which one would need heparin.
Anemia
- The body lacks sufficient red blood cells and hemoglobin, so oxygen delivery to cells isn't efficient. This wouldn't need a blood thinner.
Iron deficiency
- This is linked to anemia. The body doesn't have enough iron or red blood cells, and anemia ensues.
Hemophilia
- A genetic disease where blood can't clot. A blood thinner is meant to prevent blood clots and the blood already can't do that. It would only make the problem worse.
Thrombosis
- Involves the clotting of blood, which blocks the blood vessels. This would need a blood thinner to prevent the clots.
The best answer choice is <u>thrombosis.</u>
