Imagine a population of beetles. Yellow beetles are easier for birds to see and eat. Gray beetles blend into their surroundings, so they are less visible to birds than yellow beetles are. As a result, gray beetles are more likely to survive and reproduce, enabling the gene for gray coloration to be passed on to the next generation. This increases the frequency of genes for gray coloration in the population. Which of the following evolutionary processes does this scenario describe? a,. genetic drift
b. mutation
c. migration
d. natural 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.
