Biology 45 Introduction to Human Nutrition

This 4-unit course is a detailed, in-depth scientific look at the basics of nutrition, with an emphasis on disease prevention and treatment.  This course is offered every quarter (including the summer quarter, in the condensed 6 week format). 

Before you can register for Biology 45 you must have taken and passed the prerequisites (BIOL 40 A, B and C -- Anatomy and Physiology). If you're hoping to add this class, I cannot give you an add code (even if there is space in the class) until you have received clearance for the prerequisites. I am not able to expedite or circumvent that process.

The syllabus is provided as a web-based "liquid" syllabus. (On the first page there is a link to a traditional, printable syllabus as a pdf file)

Summer 2023 Syllabus

FYI: There are no required synchronous lectures either on campus or on Zoom for Bio 45

However, there are times that you will need to be on Zoom.  Exams will be taken online on specific days, at specific times (with a choice of times on those dates), while on Zoom with video enabled.

The dates for the 5 Exams are:

  • Exam 1 Thursdays July 13
  • Exam 2 Thursday July 20
  • Exam 3 Thursday July 27
  • Exam 4 Thursday August 3
  • Exam 5: Thursday August 10
  • You choose one of the following times to take exams 1-4 (45 minute exams): 6 pm, 7 pm or 8 pm
  • Exam 5 (1 hour exam) will be offered at 4:30 and 6 pm
  • FYI: The lowest of the 5 exam scores gets dropped. So if you take Exams 1-4 and you're happy with your scores, you do not need to take Exam 5.

Even if you've taken online courses before, watch this very short video (<3 min) to gain realistic expectations about taking classes online:  What it takes to be a successful online student

You WILL learn lots of GREAT STUFF about food, nutrition, eating, our relationship with food and much more! This class not only will help you become a better RN, but it will help YOU and your family to experience good health.

Yes, this is an academically rigorous course, but lots and lots of students get As. :-) There are "easy points" plus some Bonus Points to earn to improve your class standing.

Be Aware that  Bio 45 in the summer is fast paced:  2 weeks of the "regular" Bio 45 is compressed into 1 week of the summer quarter version. You should expect to spend at least 25 hours a week engaged in active learning for earning an A in Bio 45 in the summer
