She will give the DNA fingerprinting report to the jury which will have samples of suspect and its profile matching to the evidence found at the scene of crime.
In DNA fingerprinting hair, blood, semen, or other biological samples are required for the comparison of suspect and evidence. It depends on the unique polymorphism in their DNA.
The fragments of DNA are made to run on the electrophoresis gel and the similar bands observed will confirm the matching.
The DNA fingerprinting will provide very exact evidence if the DNA samples matched.
Answer:
After 48 hours amount left = 6.25 g
Explanation:
Given data:
Half life of potassium = 12 hours
Total mass = 100 g
Mass left after 48 hours = ?
Solution:
Number of half lives passed:
Number of half lives = Time elapsed / half life
Number of half lives = 48 hours/ 12 hours
Number of half lives = 4
At time zero = 100 g
At first half life = 100 g/ 2 = 50 g
At 2nd half life = 50 g/2 = 25 g
At 3rd half life = 25 g/2 = 12.5g
At 4th half life = 12.5 g/2 = 6.25 g
Answer:
The classic symptoms of asthma include wheezing, coughing, tightness in your chest, and feeling short of breath. But other conditions — like allergies, chronic obstructive pulmonary disease (COPD), sleep apnea, and post nasal drip — can trigger the same problems.
Explanation:
<span>Positive Rh factor represents the presence of the rhesus protein on the blood cells.</span> <span>Rh factor or Rhesus factor is used to describe the presence of antigen Rh (D) in the blood. A person who is, for example, AB Positive (AB+) has the A and B antigens and the Rh(D) antigen, whereas someone who is AB Negative (ab-) lacks the Rh(D) antigen. Antibodies to Rh antigens can be involved in hemolytic transfusion reactions and they increase the risk of Hemolytic disease of the fetus and newborn, so it is important for mother and the baby to have the same Rh factor.</span>
