Q. 35 One treatment for high blood pressure is taking diuretics that prevent the kidney collecting ducts from reabsorbing water. How would diuretics reduce blood pressure? By increasing blood volume By decreasing blood volume By increasing heart rate By decreasing heart rate

The diuretics will increase the volume of urine. That means more water is taken from the blood and excreted. According to Boyle's law, the volume is proportional to the pressure(p1v1=p2v2). It means that if we decrease the volume of blood we also decrease the pressure.

That means second option

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
