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.
Jeremy is going with dehydration and electrolyte imbalance which commonly thought to be the cause of muscle cramps. This is most evident factor when training in hot and humid conditions due to an increased loss of electrolytes through sweat.
Exercise associated muscle cramps are mainly treated with hydration and electrolyte supplementation but this could be neglecting the underlying cause of cramps during or after exercise. The most effective way of treating cramps before they affect body athletic performance is neuromuscular re-education.
What is neuromuscular re-education?
Neuromuscular re-education involves training weak, underactive muscles to help balance the work load..

The answer for this question is ‘Epidemiology’
Answer:
The correct option is: B) peristalsis
Explanation:
Peristalsis is the involuntary wave-like contractions and relaxations of the smooth muscles of the gastrointestinal tract of the humans.
These alternating contractions and relaxations produces a peristaltic wave that pushes the food down the esophagus of the digestive system. The peristaltic movement prevents the food from moving backwards and pushes the food forward.
