Question

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?
o 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?
o what is the effect of crop selection for pest resistance on the sale of green salad in grocery stores?
o what is the effect of crop selection for pest resistance on the texture most preferred for consumption by grasshoppers?

Explanation:

• The question asks for a measurable dependent variable related to the texture of lettuce affected by pest - resistance crop selection.
• Leaf size distribution (first option) is about plant morphology, not texture.
• Sale of green salad (third option) is a market - related factor, not a direct measure of lettuce texture.
• Texture preferred by grasshoppers (fourth option) is about the preference of another organism, not a direct measure of the lettuce's texture for the context of human - relevant texture concerns (since the initial concern was about how it affects the texture, likely for human - related aspects like eating).
• Toughness of lettuce leaves (second option) is a measurable aspect of texture.

Answer:

What is the effect of crop selection for pest resistance on the toughness of lettuce leaves?
