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.
Answer:
1 gene controlled by the Lac promoter and a given operator. 24. If the repressor mutant binds the operator variant, GFP expression is decreased; the stronger the binding interaction, the lower the expression. A repressor plasmid library was transformed into competent cells containing a given, single, operator.
Answer:
eating the candy bar increases the amount of sugar in the blood stream. ... when your blood sugar drops too low (hypoglycemia), your pancreas releases the hormone glucagon. glucagon then incited the release of glycogen (a sugar storage molecule) from the liver. this increases the blood sugar levels back to a normal level.
