Complete the assigned readings (Activity One).
Recall that teratogens are a recurring theme throughout the text and you will find information in other chapters in addition to the required readings for this module. For example, this information is also augmented in Chapter 17.
Prepare an essay of about 200 words addressing the following: Why retinoic acid is a teratogen. You need to specify the exact molecular mechanisms and the particular population(s) of animals for which it acts as a teratogen.
Notice that you are not expected to find an answer. There is not a single correct answer. You need to use the question as a prompt to demonstrate your understanding of the material.
Keep the following guiding questions in mind as you complete this activity taking care to ensure your response address them:
•Am I at risk from retinoic acid or is it actually beneficial?
•Where does retinoic acid appear in my day to day life? 
Complete the assigned readings (activity one), and select articles on retinoic acid from the Excelsior college library or the companion website, www(dot)devbio(dot)com.
They need not be peer-reviewed articles.
