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.
Co-dominance.
It's where both of the genes are represented and in this case, both the genes for brown and white hair will be represented.
Hope this helps :)
<em>Hi,</em>
Answer:
<em>She talks to him and explains to him that it is not painful. </em>
Answer with Explanation:
The patient above is in the condition of a "compensated/compensatory stage of shock." This stage follows the initial stage of shock. At this point, the person's body has a low amount of blood circulating in the body. However, he is still able to maintain his blood pressure as well as his "perfusion" due to the presence of "renin-angiotensine-aldosterone-system," also known as <em>"RAAS." </em>
This hormone system works by regulating the body's blood pressure. Due to low renal blood volume (the blood circulating in the kidneys), the kidneys secrete "renin." Renin then acts on angiotensin (a protein), which allows the formation of angiotensine I. Angiotensine I is converted to angiotensine II through the presence of angiotensine-converting enzyme. Angiotensine II is a potent vasoconstrictor, thus it also helps in increasing the blood volume.
The formation of angiotensine II stimulates <em>"aldosterone"</em> hormone which is released from the adrenal glands. This hormone allows water and sodium to be reabsorbed. In order to maintain a good electrolyte balance, the potassium is removed. This results to an increase fluid in the body, thereby leading to an increase blood pressure.
