General Biology 2 Course Introduction and Prokaryotic Fundamentals
Course Contact and Communication Protocol
Office Communication Caveats: The professor provided an office phone number but explicitly stated they rarely answer it because they are seldom in the office while on campus.
Primary Availability: Students are most likely to find the professor in the laboratory or teaching classes. Last-minute questions are best addressed in the lab.
Email Requirements: All electronic correspondence must be sent from a student's official Santa Fe email address. Emails from personal accounts will likely not be received or responded to due to campus policies regarding security and professionalism.
Canvas (Course Management System): The campus system, referred to as the portal for the course, will house all critical information, including course materials, grade postings, and announcements.
Registration and Administrative Procedures
Class Roster: Students are required to initial the roster next to their name. If a student's name is missing, they must write it at the bottom and immediately verify their registration status.
Registration Correction: Errors in registration must be resolved within the first couple of days of the session. Delaying these fixes can lead to significant administrative complications later in the term.
Required Course Materials
Textbook: The course utilizes Campbell Biology Twelfth Edition, published by Pearson. - This is the same textbook used in General Biology 1 (Core 1). - Students with ebook access usually have a duration of 12 months, which should cover the summer session if purchased for the previous term. - Hard copies can be purchased directly from Pearson if the bookstore is out of stock.
Laboratory Manual: A custom-written manual produced by the Santa Fe biology faculty is mandatory. - This manual is exclusively available through the campus bookstore. - Warning on Availability: The bookstore frequently under-orders this manual, leading to stock shortages in the first days of class. Restocking typically takes two weeks. - Students are required to have the manual by Thursday's session; immediate purchase is strongly advised.
Course Scope and Curriculum Overview
General Biology 1 vs. 2: The collective goal of the two-course sequence (Core 1 and Core 2) is to cover the entire Campbell Biology textbook over two semesters. - General Biology 1 Recap: Covered the first half of the book, focusing on biochemistry, cell biology, genetics, and evolutionary theory. - General Biology 2 Scope: Covers the second half of the textbook, beginning with Chapter 27.
Content Selection: Due to time constraints, the course will not cover every single chapter in the second half but will select key chapters to build a foundational knowledge base.
Initial Survey: The first section of the course involves a survey of known life forms on Earth to familiarize students with biological diversity.
Laboratory Orientation: A short lab session is held initially to orient students to the lab's unique structure, which differs significantly from the GenBio 1 lab format.
Summer Session Schedule and Structure
Duration: The summer session is 10 weeks long.
Lecture Frequency: There are approximately 20 lecture sessions during the summer, which is fewer than in the Spring or Fall semesters.
Lab Frequency: Labs meet twice per week during the summer, resulting in five more lab sessions than in regular semesters.
Adjusted Scheduling: Because there are fewer lecture slots, the professor will utilize some of the extra lab periods for lecture content. These instances are marked on the provided course outline.
Examination and Grading Policies
Lecture Exams: There are four unit exams for the lecture portion of the course. - Format: Multiple-choice, limited to 50 questions per exam. - Source Material: Questions are taken directly from the textbook. Reading the chapters thoroughly is the primary means of preparation.
Laboratory Exams: There are three lab exams throughout the semester, divided into units that coincide with lecture topics.
Grading Transparency: All grades are posted on Canvas, which automatically computes the student's current standing in the course.
Strict Evaluation: No grades are dropped, and there is no curve applied to the scores. Missing exam dates is highly discouraged due to the speed of the 10-week session.
Cognitive Science and Optimized Study Routines
Brain Training: The professor utilizes principles from cognitive science and neuropsychology to suggest study habits that improve brain function and retention, similar to how athletes use specific workout routines.
The "Backwards" Routine: Most students attend lectures first and then read the textbook. The professor identifies this as inefficient for long-term learning.
The Recommended Routine: Students should read the textbook and take notes before the lecture. - Analytical Engagement: Writing notes while reading forces the student to stop, think, and analyze, causing more neurons to fire and connect. - Classroom Engagement: Pre-reading eliminates the "frantic" need to keep up with note-taking during lecture, allowing students to focus on filling in gaps or clarifying "fuzzy" concepts. - Plain English Explanations: The professor aims to translate technical textbook language into plain English during class. Students who have already read the material can specifically ask for clarification on difficult sections.
Incentives for the Routine: - Bonus Points: Students who bring their pre-lecture notes to class and show them to the professor at the start of chaque session will earn a bonus (5 points) on the corresponding unit test. - Mastering Biology: Using the Pearson "Mastering Biology" website for optional extra credit assignments can yield another 5 points. These assignments only appear during the week a chapter is being covered. - Cumulative Benefit: Engaging in both the note-taking and the online assignments can improve a student's grade by a full letter grade ( total bonus).
Long-term Academic and Professional Significance
Foundational Knowledge: Future upper-division courses assume mastery of the Campbell text. Professors often begin where Campbell leaves off.
Standardized Testing (MCAT/PCAT): Standardized exams for medical and pharmacy school are often authored by Pearson, meaning the questions are frequently derived from the Campbell Biology textbook.
Qualifying Exams (Masters/PhD): The professor shared an anecdote regarding qualifying exams where professors use the Campbell text to test candidates. - Process: A professor might open to a random page (e.g., protein synthesis) and require the student to deliver a mini-lecture on that spot. - Consequence: Failure to pass these face-to-face verbal exams results in being asked to leave the graduate program.
Scientific Vocabulary: Building a scientific vocabulary is essential. Standardized tests include vocabulary sections where familiarity with scientific terms, meanings, and names is critical.
Introduction to Chapter 27: Prokaryotes
Definition: Prokaryotes are single-celled life forms characterized by a lack of membrane-bound organelles and specifically the absence of a nucleus.
Evolutionary Timeline: Fossil records suggest prokaryotes have existed on Earth for at least (3.5 billion) years.
Biosphere Dominance: Prokaryotes are found in every environment capable of supporting life. - Population Example: There are more prokaryote cells in a single human mouth than there have been humans in the history of the species.
Pathogens vs. Beneficial Flora: While some are pathogenic (causing disease), many are essential. - Intestinal Health: Bacteria in the gut help digest molecules humans cannot break down, leaving behind essential nutrients. - Probiotics: Healthy bacteria are essential to the "ecosystem of life." - Overuse of Antibiotics: The professor warns against the indiscriminate use of antibacterial products, which can destroy essential ecosystems.
Extremophiles: Prokaryotes can survive in extreme conditions, such as the boiling water of geysers in Yellowstone National Park. The bright colors seen on rocks near these geysers are often films of bacteria rather than the rock itself.
Biological Status of Viruses: The course focuses on prokaryotes as the simplest life forms. Viruses are generally excluded from this category as many biologists do not consider them to be living forms.
Endosymbiosis Preview: Future chapters will discuss how complex eukaryote organelles, such as mitochondria and chloroplasts, may have originated as free-living bacterial cells that were absorbed by larger cells.
Questions & Discussion
Q: What day of the week do the Mastering Biology extra credits renew? - A: They are usually due by the end of the week, such as Friday or Saturday. Some are already posted.
Q: Can you access the website if you bought the ebook? - A: Access depends on the specific purchase. If the ebook was bought through the bookstore, it should typically include access to the Mastering Biology website.
Q: How specific are the test questions regarding textbook details? - A: While everything in the chapter is technically "fair game," the professor aims to be realistic. With only 50 questions covering multiple chapters, the focus is on the main points rather than "nitpicky" details that might cause everyone to fail.
Q: What is a qualifying exam? - A: An exam taken during the first semester of a Master's or PhD program where a committee of professors tests the candidate's foundational knowledge to ensure they are "qualified" to continue the program.
