Blood and Fingerprints Essay Example
Module Four: Lab Questions 1. Which of the three types of fingerprints was the fingerprint that you examined (loop, arch, or whorl)? Within that print, what minutiae did you see?
The finger print that I examined was a loop, A Loop starts and ends at the same side, which is the side of the opening. It has one delta on the opposite side of the loops opening. The ridged lines loop around from the center of the print. 2. Compare the print of your helper with your own. Describe the similarities and differences between the two fingerprints.
Even though the prints were similar, the first set of prints were loop and the ones of my helper were whorl. A whorl is roughly circular, with the ridge lines going all the way around. They have two deltas, on opposite sides of the entire whorl. The loop starts and ends at the same side and has only one delta. So they look similar because they both spin out of the center but the loop fingerprint starts and ends on the same side and the whorl fingerprint goes all the way around and enters from both sides. 3. Imagine that you are Alphonse Bertillon and you are trying to explain why you think fingerprints can be so useful to help solve crimes. What would you say to persuade them? Pretend you are explaining to someone who has never noticed fingerprints or thought about what they are.
Fingerprints are the best way to catch a person that has committed a crime. No two persons have the same set of prints. If your prints are found at a crime scene, that means, you were there. Fingerprints are an important part of solving a criminal investigation. This type of testing is done much faster and is not as costly as other procedures. 1. Name and describe the four main components of blood.
The four main components of blood are: Red cells, white cells, platelets and plasma. 2. What antigens and antibodies determine blood type? What are the antigens made of?
The antigens and antibodies that determine blood type are A,B
