- 2. Multiple Choice
The directon of blood travel can be determined by:
the size of the blood drop
following the tail of the blood drop
the type of blood (A, B, AB, O)
the amount of blood present
- 3. Multiple ChoiceA blood drop that is perfectly round would have an impact angle of10 degrees45 degrees30 degrees90 degrees
- 4. Multiple ChoiceA gunshot wound close to the head would producelow velocity spatterhigh velocity spattermedium velocity spatternone of these
- 5. Multiple Choice
What does a "tail" on a blood stain tell you about the direction of travel of the blood drop?
the blood came from the opposite direction of the tail
the direction of the blood follows the tail
A tail indicates multiple drops of blood
A tail indicates the blood made contact at 90 degrees
- 6. Multiple Choice

Transfer or contact
Point of origin
Angle of impact
Low velocity impact

- 16. Multiple Choice
The small secondary drops of blood that are around a main drop or bool of blood as a result of the blood hitting a surface are called:
Spines
Swipe
Satellite drops
Drip Drops
- 17. Multiple ChoiceInvestigators can individualize blood evidence by:Determining the blood groupObserving the blood cellsComparing the DNA from the cellsUsing the Kastle-Meyer test
- 18. Multiple Choice
A blood droplet makes impact with a smooth surface at a very acute angle of approximately 30 degrees. How would you expect the drop to be shaped?
very long and narrow
nearly circular/spherical
circular but with spines extending from the edges
there is no way to predict the shape of the drop
- 19. Multiple Choice
One of the main differences between red blood cells and white blood cells is
red blood cells have a nucleus and DNA while white blood cells do not
white blood cells have a nucleus and DNA while red blood cells do not
red blood cells aid in fighting off infections while white blood cells transport oxygen and carbon dioxide throughout the body
red blood cells are irregularly shaped while white blood cells are round, disc-shaped cells
