100
Define BPA.
What is...Bloodstain Pattern Analysis?
100
Define Psychology.
What is... the study of the mind and behaviors of individuals?
100
This blood type is known as the universal donor.
What is...Blood type O-?
100
Examples of transfer blood stains?
What are...Smears, wipes, or (swipe) prints?
100
Worth 300 points: Determine the angle of impact if the blood droplet is 19mm in length and 9 mm in width. Round to the nearest hundredth.
What is...28.27 degrees?
200
Part of blood that is primarily made up of water.
What is... Plasma?
200
What do psychiatrists specialize in that psychologists do not?
What is...Medical treatments?
200
Determine the blood type:
Positive test with anti-A, Negative test with anti-B, and Positive test with Rh-factor.
What is...Blood type A +?
200
The width-to-length ratio of a blood stain is used to identify this aspect.
What is... Angle of Impact?
200
Worth 300 points: Determine the angle of impact if the blood droplet is 34mm in length and 28 mm in width. Round to the nearest hundredth.
What is... 55.44 degrees?
300
The term Rh Factor stands for.
Bonus points for where it was discovered in.
What is... Rhesus, and was discovered in Rhesus monkeys?
300
Explain the difference between an organized and a disorganized serial killer.
What is...An organized killer is typically more intelligent, hides the body/weapon so they do not get caught, keeps a totem, and performs the same kill style. A disorganized is the opposite, leaves the body, no totem, changes method.
300
Determine the blood type if no A and B antigens are present, but Rh antigens are.
What is...Blood type O+?
300
If a blood droplet had a diameter of 10 mm, and another's diameter is 22mm. Which bloodstain was dropped from a greater height? Explain.
What is... the 22mm Blood droplet, because the higher up a droplet comes from, the more it will spatter and fan out?
300
Worth 300 points: Determine the angle of impact if the blood droplet is 6.5mm in length and 4.8 mm in width. Round to the nearest hundredth.
What is... 47.60 degrees?
400
Instead of this structure, red blood cells have hemoglobin inside them.
What is...a Nucleus?
400
Create a profile for the typical serial killer.
Every characteristic is worth 100 points.
What is...White male, early 30s, abusive relationship, animal cruelty, bedwetting, head trauma, isolated.
400
The blood type that contains zero antibodies.
What is... Blood type AB+?
400
Explain the difference between passive and projected bloodstrains.
What is... Passive is caused by gravity. Projected is caused by a force applied to the victim.
400
Calculate the height of impact spatter if the angle of impact is 67.67 degrees and the distance to the area of convergence is 67 cm. Round to the nearest hundredth.
What is...163.12 cm?
500
Explain the difference between an antigen and an antibody.
What is... Antigens are markers (team flags) on the red blood cell. Antibodies attack opposing (team flags) antigens as they see them as a threat?
500
Explain the difference between the three types of murderers.
What is...Mass murder kills more than 4 people at a time to send a message. Spree killer kills more than one person at multiple locations (constantly moving). A serial killer has a cooling-off period and typically has the same killing pattern.
500
Create a Punnett square and explain if a mother with blood type A can have a child with blood type O, if the father is blood type B.
What is... Yes, it is possible as both parents' alleles would have to contain the recessive O type (i). Her alleles would be Ai, and the dad's alleles would be Bi. Completing a Punnett square would result in 25% to have either A, B, AB, or O blood type.
500
Explain what direction this bloodstain pattern is coming from.
What is the direction of the bloodstain is from the top right because the tails of the blood droplets indicate the direction the blood is traveling.
500
Calculate the height of impact spatter if the angle of impact is 10.6 degrees and the distance to the area of convergence is 106 cm. Round to the nearest hundredth.
What is... 19.84 degrees?
