Answer:
Normal cellular processes during the S phase of the cell cycle.
Explanation:
Antimetabolites are drugs that affect one or more enzymes which are important for DNA synthesis by acting as a substitute to the main metabolites that would be used in the normal metabolism.
Antimetabolites also act during the S phase of the cell cycle thereby contributing to cell destruction.
While Antineoplastic antibiotic agents interfere with one or more stages of the synthesis of RNA, DNA, or both which prevent normal cell growth and reproduction of the cell.
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.
Answer:
b. ex post facto or quasi-experimental.
Explanation:
An ex post facto search is done when a researcher cannot manipulate one of the variables such as sexual behavior or smoking (as described in the question), ie this type of research is done when it is not possible to manipulate the independent variables as they already arrive ready for research. Ex-post fact research deals with variables that are unmanipulated in nature. Quasi-experimental research can also be done for this same situation.
