Answer:a. This study involved comparison of two populations. What were the populations?
1) Pregnant women who took the drug.
2)Pregnant women who didn't take the drug.
b. Do you suppose the data were obtained in a survey or experiment?
- Survey
C.Provide a descriptive statistic that could be used to estimate the number of women out of 1000 in this population who have tissue abnormalities.
-out of 1,000 women developed tissue abnormalities
63/3980=.0158
15.8%
D. remember that women whose mothers took the drug were twice as likely to develop tissue abnormalities.)
___ out of 1,000 women developed tissue abnormalities
15.8/2
7.9
e. Medical sudies often use a relatively large sample (in this case 3980). Why?
medical studies often use a relatively large sample (in this case, 3980) because disease occurrences can be rare and difficult to observe when only isolated populations are considered.
Answer:
False.
Explanation:
Intravenous drug administration consists of applying a drug directly into the patient's vein. This type of drug administration promotes more accurate observations on the drug's effects on the patient's body and on the drug's effectiveness in fighting the disease, mainly because intravenous administration allows the drug to act faster, even when applied in large volumes.
A primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak
<h3>What is antigenic drift?</h3>
Antigenic drift is a phenomenon that causes small changes or mutations in the genes of influenza viruses leading to changes in their surface proteins of the virus, which are HA (hemagglutinin) and NA (neuraminidase).
For this reason, new influenza vaccines are produced yearly to alter the effects that may emerge as a result.
Thus, a primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak

Answer:
The debates over vaccinations are often cast as arguments over the integrity of science. But they can just as easily be understood as conversations about power, writes Eula Biss, a senior lecturer at Northwestern University, in her book, On Immunity: An Inoculation. As it stands, all 50 states require specific vaccines for school-aged children, although each grants exemptions for students unable to be vaccinated for medical reasons. The power struggle—pitting parents against parents—arises in the 19 states that allow families to opt out of vaccination requirements by claiming a "philosophical exemption," whether based on personal, moral, or religious beliefs.
