Answer:
Kindly check explanation as the question seems incomplete but the explanation should help.
Explanation:
Given the following :
Initial dosage of drug = 100mg
Halflife of drug = 6hours
After 18 hours, the percentage of drug that will be in the system should be :
Half-life is the time taken for a material to reduce to half of it's initial size.
Since half life = 6 hours
After 6 hours ; amount left = 100/2 = 50 mg
After 12 hours ; amount left = 50/2 = 25mg
After 18 hours ; amount left = 25/2 = 12.5mg
Hence, after 18 hours percentage left in system :
(Amount left / total initial amount) × 100%
(12.5 / 100) × 100%
0.125 × 100%
= 12.5%

Answer: d. Confounding
Explanation:
In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).
For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). <em>Controlling</em> for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.
Answer:
Application or Implementation including its Clonal personality psychology for Rubeola infectious disease in something like a 6-year-old child is given below.
Explanation:
<u>Clonal Selection Theory:</u>
This hypothesis notes that lymphocytes have virulence genes preceding activation and also that spontaneous mutations throughout clonal expansion induce the formation of lymphocytes containing strong affinity antigen affiliations.
<u>Its applications are given below:</u>
- Throughout the situation of Rubeola infectious disease in such a 6-year-old boy, as shown by this hypothesis, B-cells that distinguish after such an innate immune system forming phase selection because then antioxidants formed by younger memory B cells provide significantly higher commonalities to certain antigens.
- As a result, secondary physiological systems from memory blocks have become so successful that persistent Rubeola attacks with much the same virus are prevented unless setting up.
- After the primary outbreak, genetic mutations throughout clonal selection may generate recollection B cells which could attach to implementation more effectively than those of the initial B cells.
