Lab: Natural Selection Assignment: Reflect on the Lab Active Apply the Simulation to the Real World Researchers can genetically select lettuce crops to cultivate for pest resistance. One of the concerns scientists have about genetically selected crops is that some traits for pest resistance may affect the texture of lettuce. What question could be asked to begin this investigation by looking at a measurable dependent variable? * What is the effect of crop selection for pest resistance on the distribution of leaf size in a population of plants? O What is the effect of crop selection for pest resistance on the toughness of lettuce leaves? What is the effect of crop selection for pest resistance on the sale of green salad in grocery stores? What is the effect of crop selection for pest resistance on the texture most preferred for consumption by grasshoppers? RETRY
