Researchers can genetically select lettuce crops to cultivate plants that are pest-resistant. one of the concerns of genetically selected crops is that some traits such as tough leaves for pest resistance may affect a suitable taste and texture desired by humans for eating. what question could be asked to begin this investigation by looking at a measurable dependent variable?
a. what is the effect of crop selection for pest resistance on the taste and texture most preferred for consumption by humans?
b. what is the effect of crop selection for pest resistance on the distribution of leaf size in a population of plants?
c. what is the effect of crop selection for pest resistance on the sale of green salad in grocery stores?
or d. what is the effect of crop selection for pest resistance on the taste and texture most preferred for consumption by grasshoppers?
