a reference to the speed of the object (weapon) striking the body (the source of the blood).
luminol
antigen - antibody response
hemoglobin
velocity
angle of impact

Explanation:

Each definition is matched to the corresponding forensic/biology-related term based on the core description of the term's function or structure.

Answer:

1. Angle at which blood strikes a target surface relative to the horizontal plane of the target surface. → Angle of impact
2. A compound extremely sensitive and can detect bloodstains diluted as much as 300,000 times); detect blood. → Luminol
3. A red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a heme group. → Hemoglobin
4. Reaction in which antibodies attach to specific antigens; causes agglutination in cross blood-type transfusions. → Antigen-antibody response
5. A reference to the speed of the object (weapon) striking the body (the source of the blood). → Velocity
