Answer:

1.What type of reaction is the health care provider concerned about and why?The health care provider concerned about the an IgE mediated allergic reaction. Inthe past, E.O. was given penicillin and had a sign of immune response to the drug.E.O. body has already produce Ig. E. If she uses the penicillin again, it may cause an increased allergic reaction. 2.Explain the role of IgE and mast cells in type I hypersensitivity reactions. Why might E.O. react adversely to the antibiotic with the first use?-The first exposure to an antigen causes B-lymphocytes to produce IgE-The second exposure to the same antigen causes cross links the IgE and mast cell degranulation and release of histamine, serotonin lead to rapid constriction of vessels and causing the hypersensitive reaction. -In the past, E.O.’s body had not produce the IgE immuglobin to penicillin. But at this point, her body is already produce it, and she might has some reaction to the drug. 3.What would you tell E.O.’s parents to look for when they are assessing for a reaction?Itching, angioedema, edema of larynx, uticaria, bronchospasms, vomiting, abdominal cramps, diarrhea

Answer:

a. conservative replication

b. semi conservative replication

c. dispersive replication

d. discontinuous replication

e. continuous replication

The CORRECT ANSWER IS C.

c. dispersive replication

Explanation:

The attached image shows a single band that becomes lighter (in volume) and increase in darker intensity (in times of color) is revealed with consecutive replications. The major pattern that would produce these outcome is dispersive replication.

Conservative replication do reveal two bands (a 14N for the wholly latest molecule, and a 15N for the totally antiquated molecule) after the initial replication. Therefore, this wholly wrong.

Semi-conservative replication reveal an individual band of transitional weight after the initial replication, followed by two bands following the second replication (one of transitional weight, and the other at the 14N position). These two bands is observed in each following replication, with the transitional weight becoming lighter in color as the 14N band is seen to appear darker in color.

The real pattern gives an individual band that pinpoints to all molecules in an individual replicative cycle possessing the same constituents.

Dispersive replication, has its molecules to be a blend of old (15N) and new (14N) strands. Each replication raises the ratio of new to old strands as it explains the reason an individual band is shown raised (lighter in weight) with every replication.
