Answer:
Incidence
Explanation:
Isaac will need to assess the incidence rate of HIV-infected adolescents for his research. This must be done because Isaac's research wants to gauge the speed with which this virus is spreading among teens. For this, Isaac must make a comparison between the existing number of patients who fit this case, with patients who fit the recent cases of incidence of the disease. That is, when conducting his research, he will want to examine the number of new cases, the incidence of the disease.
Answer:
The best answer to the question: Which hygiene claim is supported by research? Would be: B: Brushing with a fluoride toothpaste helps prevent cavities.
Explanation:
We can first start this by saying, that right off the bat, we can totally rule out options C and D as a correct answer. Research, in fact, has shown, first that antibacterial soap does not have a higher impact on overall disease acquisition than regular soap, and rather, it does affect health because antibacterial soaps kill even normal bacterial groups on human skin that are necessary for skin balance. Also, handwashing was been shown to be beneficial in reducing the incidence of infection. On options A and B, although professional teeth cleaning does help in overall mouth welfare, it is not paramount, or vital, and therefore does not have to be regular if a person carries out his/her personal hygiene in the proper manner. However, what research HAS shown is that even if a person does a full care process of his/her teeth (brushing, flossing, etc,) if that person does not use fluoride in toothpaste, he/she will be prone to dental cavities as it has been shown that fluoride does impact the ability of bacteria to cause cavities. This is why the answer is B.
