Paul Andersen describes how free energy is used by organisms to grow, maintain order, and reproduce. A brief discussion of the first and second law of thermodynamics is also included.
BioNetwork provides high-quality economic and workforce development for the biotechnology and life science industries across North Carolina through education, training, and laboratory resources.
Paul Andersen explains how linked genes behave and how linked genes were discovered. He shows how linked genes would be reflected in a dihybrid cross using a fruit fly simulator. He uses chromosome-based Punnett squares to explain why the frequency of recombination is less that 50%.
Paul Andersen explains how populations eventually reach a carrying capacity in logistic growth. He begins with a brief discussion of population size ( N ), growth rate ( r ) and exponential growth. He then explains how density dependent limiting factors eventually decrease the growth rate until a population reaches a carrying capacity ( K ).

![Majors Animal [or Cellular or Plant] (BIOL 212)](https://img.oercommons.org/160x134/ncccs-production/media/upload/materials/screenshots/materials-course-26921.png)
This is the second in a series of majoręs biology classes covering the principles of biology. The course is an integrated study of basic concepts concerning animal biology emphasizing animal evolution, diversity, phylogeny and a comparative look at general principles of animal form and function. This course is a lab science class and students will be required to participate in weekly lab activities and document their lab work for successful course completion.
![Majors Animal [or Cellular or Plant] (BIOL 213)](https://img.oercommons.org/160x134/ncccs-production/media/upload/materials/screenshots/materials-course-26922.png)
Biol & 213 is the third course of a year-long series of biology courses for Biology majors. The first third of the course surveys prokaryotes, protists, fungi, and plants, focusing on diversity, evolution, and life cycles from an evolutionary perspective. We will then describe plant anatomy, physiology, growth, responses to the environment, and reproduction, emphasizing flowering plants. We will finish with ecology, focusing on population, and community ecology and expanding outward to ecosystems and the introduction of biodiversity and conservation.
![Majors Cellular [or Animal or Plant] (BIOL 211)](https://img.oercommons.org/160x134/ncccs-production/media/upload/materials/screenshots/materials-course-26923.png)
This course is the first in a three-course sequence that introduces biology in preparation for advanced study in areas of biological science such as medicine, dentistry, cell biology, microbiology, or veterinary medicine. Biol& 211 introduces students to cellular structure and function. Major topics studied include: energy capture and utilization, cellular reproduction, inheritance, genetic mutation, protein synthesis, gene expression, and biotechnology.

Paul Andersen describes mechanisms that increase the genetic variation within a population. He begins by discussing how horizontal transfer can move genetic material between bacteria. Transformation, transduction, and conjugation in bacteria are all included. He also explains how crossing over, random assortment, and random fertilization can maintain genetic variation in eukaryotes.
Paul Andersen explains how organisms regulate timing and control. Phototropism and Photoperiodism allow plants to respond to light throughout the day and year. Circadian rhythms are used in all organisms (including animals) as an internal clock. Bacteria use quorum sensing to communicate the number of bacteria present.
Paul Andersen explains how the process of meiosis produces variable gametes. He starts with a brief discussion of haploid and diploid cells. He compares and contrasts spermatogenesis and oogenesis. He explains how each person is different due to independent assortment, crossing over and random fertilization.
The video resource "Meiosis: Where the Sex Starts - Crash Course Biology #13" is included in the "Biology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.
Paul Andersen explains simple Mendelian genetics. He begins with a brief introduction of Gregor Mendel and his laws of segregation and independent assortment. He then presents a number of simple genetics problems along with their answers.
This "Mendel's Law of Independent Assortment and Gamete Diversity" learning object is the from the Sumanas resource series. Sumanas offers a robust selection of content and services that are directed at enhancing the learning experience.
Paul Andersen explains how the Meselson-Stahl experiment was used to prove that DNA copied itself through a semi-conservative process. They grew E. coli in a medium containing heavy nitrogen (N-15). They then added the E. coli to a medium containing regular nitrogen (N-14) and observed it over several generation.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.
As a group of organisms that are too small to see and best known for being agents of disease and death, microbes are not always appreciated for the numerous supportive and positive contributions they make to the living world. Designed to support a course in microbiology, Microbiology: A Laboratory Experience permits a glimpse into both the good and the bad in the microscopic world. The laboratory experiences are designed to engage and support student interest in microbiology as a topic, field of study, and career. This text provides a series of laboratory exercises compatible with a one-semester undergraduate microbiology or bacteriology course with a three- or four-hour lab period that meets once or twice a week. The design of the lab manual conforms to the American Society for Microbiology curriculum guidelines and takes a ground-up approach -- beginning with an introduction to biosafety and containment practices and how to work with biological hazards. From there the course moves to basic but essential microscopy skills, aseptic technique and culture methods, and builds to include more advanced lab techniques. The exercises incorporate a semester-long investigative laboratory project designed to promote the sense of discovery and encourage student engagement. The curriculum is rigorous but manageable for a single semester and incorporates best practices in biology education.
