A person enters a room, flips the light switch, and a lamp turns on. What causes the lamp to turn on?
the circuit is open, flipping the switch closes it
Person X and person Y both smoked the same brand and amount of cigarettes for 20 years. Person Y develops lung disease while person X does not. Why?
the genetic makeup of person x allowed for a higher tolerance to chemicals in tobacco than person Y
Why do thunderstorms most often occur in the summer months?
higher summer temperatures increase the rate of evaporation and convection
