Consider that you are a developmental biology researcher working on studying the development of your DEV2011 cell type (the one you have been assigned this Semester). 

1) You have a fixed embryonic section, and want to see if a particular protein is found in your cell type as it is developing.  What technique (staining and imaging, eg haematoxylin, light microscopy) would be the best to use to answer this question, and why?  (3 marks)  

2. You are designing a study to model the human development of your DEV2011 cell type in a model organism. In which of the following organisms would you choose to undertake this study, and why? Choose from C. elegans (worm), X. laevis (frog), or D. rerio (zebrafish). (3 marks)

NOTE: There is a word limit of 100 words total for this answer (ie 100 words for combined answer 1 and 2). You can use dot points and keep your answer concise.  Your answer will still submit even if it is over the word limit.
