[EX Q]: Question: If Milo starts rubbing two surfaces together quickly and then decrease the speed, what happens to the amount of energy produced? 
 Answer: decreases
[EX A]: Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer.

[EX Q]: Question: A decrease in protein production indicates _____ ribosomes on the ER. 
 Answer: less
[EX A]: The folds present in the membrane increase the surface area allowing more ribosomes to be present on the ER, thereby allowing greater protein production.

[EX Q]: Question: Officer Ricky points a radar gun at a car. A slow car likely has _____ frequency waves bouncing off of it. 
 Answer: lower
[EX A]:
A: As the car approaches the radar gun, the reflected microwaves get bunched up in front of the car. Therefore, the waves the receiver detects have a higher frequency than they would if they were being reflected from a stationary object. The faster the car is moving, the greater the increase in the frequency of the waves.
