Astorm washed five female and five male tiger beetles from the mainland to a small island that had no previous population of tiger beetles. in tiger beetles, having six spots (a) is dominant to having four spots (a). all ten beetles had six spots, but one male and one female were heterozygous for the four-spot trait. if six of the beetles died randomly without reproducing, the ratio of the genotypes could be quite different in subsequent generations. this change in allele frequencies would be an example of: a. gene flow b. mutation c. genetic drift d. disruptive selection e. sexual selection

Acar company is testing seatbelts using crash test dummies. the company finds that when cars come to a sudden stop, the crash test dummies' bodies continue to move forward. the seat belt keeps the crash test dummies from hitting the back of the seat in front of them. why do the crash test dummies' bodies continue to move forward even though the car stopped? a. the friction opposing their bodies' movement keeps them in motion. b. the inertia of their bodies keeps them in motion. c. the forward acceleration of the car keeps them in motion. d. the gravity pulling on the car keeps them in motion.
