Botanist Dr. Lisa Patel studied the defense mechanisms of the wild cabbage plant (*Brassica oleracea*). Patel claimed that wild cabbage plants increase their production of mustard oils—chemical compounds that deter pests—specifically in response to insect feeding, rather than maintaining high levels of these oils constantly.
Which choice, if true, would most directly support Patel's claim?
- AWild cabbage plants grow faster and produce more seeds in areas with fewer insects.
- Wild cabbage plants that were subjected to insect feeding showed a significant rise in mustard oil levels, while undamaged plants maintained low levels.Cevap
- CInsects that feed on wild cabbage plants have developed a high tolerance to mustard oils over time.
- DWild cabbage plants maintained constant, high levels of mustard oils regardless of whether insects fed on them.
Cevap
The choice stating that wild cabbage plants subjected to insect feeding showed a significant rise in mustard oil levels, while undamaged plants maintained low levels.
The correct answer is supported by evidence that wild cabbage plants subjected to insect feeding showed a significant rise in mustard oil levels while undamaged plants maintained low levels. This directly demonstrates that the production of mustard oils is a dynamic response to insect feeding rather than a constant, unchanging state, supporting the researcher's claim.
