At 1:00 a. m., someone breaks a window in the back of a store and robs the safe. On the way out, the thief cuts himself (or herself) on a piece of the broken glass. You are a forensic detective called to the scene. You test the sample of blood left behind by the thief. It is O-. While you are there, police bring in a suspect with a cut in the forearm who was arrested just three blocks from the store. You take a sample of the suspect’s blood and mix it with anti-A. You immediately know that the suspect is not the person who cut himself on the broken glass in the store. How do you know this? 2. Suppose the same suspect's blood does not agglutinate when tested with anti-A or anti-B, but does agglutinate when tested with anti-Rh. Would this connect the suspect with the crime scene? Explain
3. Tom and Jane participate in a Red Cross blood drive. Both are first-time donors. As part of the screening.
A. What ABO antibody is found in Tom's blood?
B. What ABO antigens are found in Janes blood?
4. The same Tom and Jane's blood donations are sent to a processing center where the blood cells from the plasma in each of the two samples. The separated cells and plasmas are then sent to a hospital. A blood researcher wishes to use Tom's blood in an attempt to extract and identify the A antigen. Should she attempt the extraction process on his blood cells or on his plasma?

A blood test is done by using chemicals that coagulate with the blood sample if it is positive for the test.

1. The suspect was not the same person was determined by using the blood test.

2. If the blood sample does not agglutinate for both the Anti A and Anti B antibodies it indicates the blood type to be O.

3. A. Tom's blood group is A+ the ABO antibody can be determined by:

B. Jane's blood group is AB+ which means that Jane has both the antigen A and B in her blood cells while there are no antibodies in her plasma.

4. The process of the extraction of antigen A from Tom's sample should be done from the blood cells as RBC contains the antigen while plasma is of no use because they contain the antibodies.

Explanation:

When a blood group matches with an antibody it agglutinate this indicate an agreement furthermore when they do not agglutinate it denotes they aint compatible.

The suspect's whose blood is unknown on mixing with anti-A blood agglutinate and is immediately ruled out this is because the criminal who is 0- should agglutinate with anti-B.

When the suspect blood agglutinate on testing with anti-Rh it indicates that the suspect is O+ and not O-

Plasma are mostly filled with water blood samples should be extracted from blood cell.

it's anything that aren't producers and consumers.

explanation:

you've got to be clear on what "this" is
