ss7ja [257]

Answer:

The correct term is - extrinsic stain.

Explanation:

Extrinsic stains are normally present on the surface of a tooth and occur due to taking pigmented beverages such as coffee, tea, carbonated drinks, caramel coloring, and foods. Smoking cigarettes is also one of the reasons that can cause an extrinsic stain.

This can be removed by dentists or professionals like hygienists. The stain particles act on the outer surface of the teeth and pigmented them which cause stain yellowish or brownish in individuals.

In a case-control study of obesity and adult-onset asthma, controls are matched to cases on the basis of race and gender.

Bess [88]

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.

How do vaccines work? Do they work against viruses and bacteria? Why there<br> are so many vaccines.

Liono4ka [1.6K]

Answer:

Vaccines train our immune systems to create proteins that fight disease, known as ‘antibodies’, just as would happen when we are exposed to a disease but – crucially – vaccines work without making us sick. Live, attenuated vaccines fight viruses and bacteria. These vaccines

contain a version of the living virus or bacteria that has been weakened

so that it does not cause serious disease in people with healthy immune

systems. Because live, attenuated vaccines are the closest thing to a

natural infection, they are good teachers for the immune system.

Examples of live, attenuated vaccines include measles, mumps, and

rubella vaccine (MMR) and varicella (chickenpox) vaccine. Even

though they are very effective, not everyone can receive these vaccines.

Children with weakened immune systems—for example, those who are

undergoing chemotherapy—cannot get live vaccines. Those are only some vaccines, of course not all vaccines inject a live virus into your body. And of course, there are so many vaccines because (unfortunately) there are so many diseases!
