                                Q2:
                                
What is Stable Isotope Analysis used in tracking the migration of the Painted Lady Butterfly?

                            
                        

                                                

                            
A: A method that uses isotopic markers to distinguish genetically different populations

                            
B: A process that studies isotopic compositions in wings to determine the region where the butterfly developed as a larva

                            
C: A technique that uses radio signals to track real-time movement patterns

                            
D: A process that involves tagging butterflies with chemical markers to trace migration routes

                        

                        

                            
                        

                        

                            

                                
 Answer:  B

                                
 Explanation:

                                
Stable isotope analysis examines elements like hydrogen and strontium in butterfly wings. Since wings do not metabolically change after development, the isotopic composition reveals the geographical location where the butterfly lived as a larva.

                                

                            

                        

                    

                

                            

                    
                    

                        

                            
                                Q3:
