SYNOPSIS OF CHAPTER 5: VEGETARIAN LIFESTYLES, GENERAL GUIDELINES

As specified in the syllabus, you are expected to provide synopses of two chapters of the textbook. These are the general guidelines for the first synopsis, which is on chapter 5: Vegetarian Lifestyles. The purpose of the synopses is to ensure that you are properly engaging with the material covered in the textbook, and are properly integrating the basic biology of the insects that we discussed in lectures on the ways in which insects impact humans. To this end, her I provide you with a series of questions to guide your reading and facilitate your synopses. Your synopses should be concise, but complete, answers to these questions.

ALL questions specify the maximum number of words required for your answer, and you must observe those word limits. Type your answers into this worksheet and upload them to the link provided on Moodle as a MS word document. DO NOT upload PDF files as I cannot process (grade) pdf files. Your synopsis 1 is due at 11:55 pm, on Sunday January 31, 2021.
