The signs of dehydration include symptoms that indicate the body's water levels are insufficient. Dry mouth and fatigue are indeed common indicators of dehydration because when the body lacks adequate fluids, it struggles to maintain normal functions. A dry mouth results from reduced saliva production, while fatigue arises as the body becomes unable to perform tasks effectively due to a lack of hydration, affecting energy levels and physical performance.

In contrast, excessive sweating and high blood pressure is not a typical sign of dehydration, as high blood pressure may not necessarily correlate directly with fluid levels. Similarly, increased appetite and high energy levels contradict the typical manifestations of dehydration, as individuals who are dehydrated generally experience fatigue and reduced energy. Bright yellow urine is a result of concentrated urine, indicative of dehydration, but frequent urination is not consistent with dehydration; typically, dehydration leads to reduced urine output as the body tries to conserve water. Thus, the correct choice highlighting signs of dehydration includes dry mouth and fatigue.
