Course description: 

Prerequisite: MATH 090. A comprehensive one semester general biology course for non-majors. Includes life from the molecular to the organismic level of both plants and animals and their interactions within the environment. Special emphasis is put on human biology within appropriate areas of study. Appropriate for general education as well as nursing, pre-professional, and higher level biology courses. Includes laboratory component. (CSU) (UC credit limited. See a counselor.)

Textbooks and other materials:


1.      Audesirk, T., G. auderisk, and B. E. Byers. 2009. Fifth Edition (although any edition will probably be fine). Life on Earth. Pierson/Benjamin Cummings, San Francisco, CA
2. Lab Manual, Principles of Biological Science
, Imperial Valley College, Science, Math, and Engineering Division


3. Safety Goggles - Available at IVC bookstore. If you wear glasses then you DO NOT have to wear the safety goggles.


 Attendance Policy:

Attendance is required
.  You will be responsible for all material presented during lecture and lab sessions.   If for some reason you can't attend a lecture, quiz or an exam you must provide a signed medical or legal excuse to document your absence in order for your absenceto be excused.  Students must realize that labs CANNOT be made up (regardless of the extracurricular activity that resulted in the absence, or whether its an excused absence). Some labs require numerous hours to prepare and/or require cooperative student participation.  Lab practical exams may not be made up.  Thus, attendance is mandatory at all labs.  If you miss a lab, you must see me immediately and provide a signed medical or legal excuse to document your absence.  All research indicates that there is a strong positive correlation between class attendance and good grades (i.e., those who attend class get better grades than those who skip class).        

Class attendance and tardy policy follows regulations set forth in the IVC catalog. Additionally, the IVC catalog states "disruption of a class can result in disciplinary action."   I consider coming into class tardy - a disruption.  Any student tardy/absent 3 times (in any combination) will be considered a disturbing element in class and will be directed to student services for discipilnary action.  This includes being tardy following any announced breaks during class or lab.   


Please note that personal issues, such as family obligations, family situations, border slowdowns, babysitters, sick babies, railroad crossings, job interviews, car problems and work schedules are not acceptable excuses for an absence or a tardy.  You are allowed one tardy. For all subsequent tardies you will be asked to provide a 4 page essay on the topic we are covering on that day. This will be due at the beginning of the next class. Failure to provide a 4 page (double spaced, 12 font) will result in the loss of 30 points. If you miss more than 1 hour of a daily lecture you will be recorded as absent. Additionally, leaving class or lab before it has been officially dismissed will be regarded as as an unexcused absense, and will result in an essay as described above. 

    It is the responsibility of the student to fill out the necessary paperwork if he/she no longer attends the class.  In order for a student to "officially" drop the course he/she must fill out the proper paperwork (this can be done on-line).  If this is not done, a semester grade of “F” will be assigned. 

Honor Policy:


       Imperial Valley College students must conduct themselves in accordance with the highest standards of academic honesty and integrity.  Academic dishonesty by a student will not be tolerated.  Plagiarism or violations of copyright policies are a form of academic dishonesty and are treated as an ethics violation.


You will lose 25 points each time your cell phone rings, vibrates, buzzes, flashes or blinks during lecture or during lab (even if it is in your backpack or purse!).  Similarly you will incur the same penalty if I observe you "checking" your phone by looking at it, or using it as a calculator during a lecture or lab. If I see you using your cell phone for any reason you will be asked to leave the class. You can be sure that I will provide you plenty of time to take care of all of your social networking needs. If you go to the restroom during class or lab leave your phone on the desk. You may provide your children's daycare and family health providers the phone number of the IVC Front Office so the office may contact you in class in the event of an emergency. Your course grade will be based on 5 lecture exams, 5 lab practical exams, lab and lecture quizzes, and assignments.  Unannounced quizzes may be given during lecture and lab.  Review sessions prior to exams will be arranged if there is an interest. 
  • Approximately 5 - 10 homework, lab assignments, and/or announced or unannounced quizzes (10-20 points each approximately)
  • 2 lab practical exams (80 points each approximately)
  • Five lecture exams to cover lectures, textbook, CD-roms, videos, and other lecture/lab materials (80 points each approximately - the final will be partially comprehensive.
  • One Scientific Literature writitng assignement (50 points).
  • Total = ~700 points (approximate)

    Grades will be assigned according to the following scale:

    >90%  = A          
    80 - 89.9%  = B 
    70 - 79.9%  = C
    60 - 69.9%  = D
    <59.9%  = F 
I do not accept late homework without a signed legal or medical excuse

Special Needs and Accommodations

Any student with a documented disability who may need educational accommodations should notify the instructor or the Disabled Student Program and Services (DSP&S) office as soon as possible (DSP&S, Room 2177, Health Sciences Building (760 355-6312). If you have emergency medical information to share with me, or if you need special arrangements in case the building must be evacuated, please see during the first week of class.


Course Objectives

  1. identify the basic characteristics of all living things.
  2. name basic chemical aspects that pertain to life and the concept of homeostasis.
  3. describe the subcellular components of the cell including their structure and function.
  4. explain the light and dark reactions of photosynthesis.
  5. explain cellular respiration and its relations to the entire organism.
  6. demonstrate knowledge of the structure and function of DNA and RNA.
  7. explain protein synthesis and site the central dogma of cell biology.
  8. compare and contrast the fundamentals of asexual and sexual reproduction.
  9. define ecology and the overall impact of ecology to conditions in the environment.
  10. solve problems in general genetics and in human genetics and relate advances in genetics to social responsibility of geneticists.
  11. identify and relate the functions of the major systems of the human body; the interrelationship among body systems and nature of disease.
  12. classify organisms in the kingdoms of plants and animals,discuss their evolutions and their relationships.

Student Learning Outcomes

Upon course completion, the successful student will have acquired new skills, knowledge, and or attitudes as demonstrated by being able to:

  • respond to critical thinking applications of biological scenarios. (ILO2)
  • attend and arrive on time for class and lab meetings. (ILO3)
  • communicate ideas in biology clearly. (ILO1)
  • perform lab activities properly and correctly analyze lab data. (ILO1, ILO2)
