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. Having read the above passage, choose the right answer to the following question (choices are faster or slower ): Tina is speeding on the highway, and a cop is sat on the road with a radar gun to see who to pull over. The cop's gun begins to detect a low frequency, with waves reflected being bunched up. The car was going faster or slower?
slower

Having read the above passage, choose the right answer to the following question (choices are increases or decreases ): If a car and a truck drive away from each other, what happens to the gravitational attraction between the two vehicles increases or decreases?
decreases

Q: The smaller a population is, the more allele frequencies may drift. Having read the above passage, choose the right answer to the following question (choices are Milo or Jerry ): If Milo is part of a larger population then Jerry is, which person's population will experience greater drifting of allele frequencies Milo or Jerry?
A: Jerry
