FoundationWhich comparison of sharp plant structures is botanically correct?
Need a small nudge?

Classify by developmental origin, not by casual appearance.

UnderstandingWhich statement about alkaloid-related plant defense is most precise?
Need a small nudge?

Choose the statement that preserves chemical diversity and context.

ApplicationA caterpillar wounds a leaf, and jasmonate signaling increases defensive metabolites and herbivore-induced volatiles. What is the best interpretation?
Need a small nudge?

Use mechanistic language and avoid intention or guarantees.

InterpretationIn a documented ant–acacia mutualism, what exchange can make the relationship beneficial to both partners?
Need a small nudge?

Look for a food-or-housing-for-defense exchange in a named system.

ConnectionSome Passiflora species bear structures resembling Heliconius eggs, and experiments in particular species pairs show reduced egg laying. What is the strongest conclusion?
Need a small nudge?

Preserve both the observed effect and its species-specific scope.
