Exam points
- explain how internal or external environmental cues can trigger behavioral or physiological responses
- represent a stimulus-to-response pathway and use controlled data to connect an environmental variable with an organismal response
- explain how organisms exchange information in response to cues and how that information can change behavior

[Maximum number: 5]
Many insects rely on pheromones (chemical signals) that are released by the females to find
mating partners. Scientists hypothesize that, in a certain type of moth, the behavior of male
moths in response to pheromones is regulated by the extracellular signaling molecule 20E.

Question (i)
(i)
Using the template in the space provided for your response, construct an appropriate
type of graph that represents the data in Table 1. Your graph should be appropriately
plotted and labeled.
