The document provides instructions for students to complete an assignment on fixed action patterns and natural selection. Students are asked to: 1) Highlight objective 1, 2, and 3 command terms in different colors for class discussion. 2) Define key terms related to stimuli and responses. 3) Label structures of the spinal vertebra and draw a reflex arc. 4) Explain the roles of receptors, neurons, and effectors in responses to stimuli. 5) Discuss how natural selection has affected the fixed action patterns of different species based on evidence from scientific articles.

2. Stimulus A change in internal or external environment that is detected and elicits a response. CITATION Ste104 1033 (1)ResponseReflex

3. Label the structures of the spinal vertebra shown in the image (including ventral and dorsal roots)

4. Draw the reflex arc for pain withdrawal on top of the diagram. Label white and grey matter, spinal cord, spinal nerves, receptor cell, sensory neuron, relay neuron, motor neuron.

5. Explain the roles of the following in the animal response to stimulus.

6. ReceptorsSensory NeuronsRelay neuronsMotor neuronsSynapsesEffectors

7. Explain the advantages of the pain reflex being mediated by the spinal column rather than being a learned, brain-mediated response.

12. State another term for Fixed Action Pattern.

13. ……………………………………………………………………………………………………………………………………………..

14. Fixed action patterns are not learned – they are genetic in basis, can be inherited and are therefore subject to mutation, variation and natural selection.

15. Explain how natural selection affected the migratory patterns of Sylvia attricapilla.

16. Common nameOriginal fixed action patternAlternate behaviourAdvantage to individualsEffect on natural selectionExperimental evidence

17. Explain how natural selection has affected the fixed action patterns of one other species.

18. Name (latin & common)Original fixed action patternAlternate behaviourAdvantage to individualsEffect on natural selectionExperimental evidence

19. Read one of the articles. Outline how fixed action patterns have been changed through natural selection and discuss the article with your peers.
