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?

Answers

Answer 1

Answer:

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.

Answer 2

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.

When the sample from the suspect is taken and mixed with the Anti A it would have got coagulated.

For a blood sample to be O⁻ it should not agglutinate with either Anti A or B antibodies as the blood group O does not contain any antigen on its cell surface.

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.

But if agglutinates with the anti-Rh that means that it is an O⁺ blood group and not O⁻.

Therefore, it cannot be connected with the crime scene.

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

According to the ABO blood group system, two types of antibodies are present antibody A and B in the plasma while two types of antigens anti - A and B are found in the blood cells.

Tom have blood group A+ that means that he has antigen A in his RBC while antibody B is in his plasma.

Therefore, Tom has antibody B in his blood as he is A+.

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.

A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because

Answers

Answer:

This question lacks options, the options are:

A) she did not believe the new formula helped plants grow better than the old formula.

B) it was necessary to see data from more plants before the conclusion could be accepted.

C) it was necessary to have tested the fertilizer on different kinds of plants.

D) she thought he should test additional fertilizer formulas on the same two plants.

The answer is B.

Explanation:

In an experiment, a TRIAL or RUN is refers to repetition of the experiment using the same procedure. A trial is done in order to ensure that the results of the experiment is not based on CHANCE but CERTAIN. It is important that before an experiment be accepted as valid, it must be able to be replicated severally.

In this case, a student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. However, after arriving at a conclusion based on his experimental results, his teacher told him he needed to conduct additional trials. This is because, according to the importance of trials above, IT WAS NECESSARY TO SEE DATA FROM PLANTS BEFORE THE CONCLUSION COULD BE ACCEPTED.

This, in essence, means the students need to repeat the test of the fertilizer formula on more rose plants.

The Punnett square, showing a cross between two parents with at least one R (rolling the tongue) allele, is mentioned below.

What is a Punnet square?

A Punnett square is a graphical tool used by geneticists to predict the probability of offspring genotypes resulting from a cross between two parents with known genotypes.

In the Punnett square, the uppercase R represents the dominant allele for tongue rolling, and the lowercase r represents the recessive allele for not being able to roll the tongue.

The possible offspring genotypes are shown in the boxes within the table. The ratio of genotypes is 1:2:1, with 25% of the offspring having the homozygous dominant genotype (RR), 50% having the heterozygous genotype (Rr), and 25% having the homozygous recessive genotype (rr).
