Mr. Andersen describes the two portions of the AP Biology Test. Tips for answering multiple choice and free response questions are included. Sample questions from old AP tests are also included.
Paul Andersen explains the structure, function and importance of adenosine triphosphate (ATP). He begins by describing the specific structure of the molecule and its three main parts: adenine, ribose sugar, and phosphate groups. He explains how energy can be stored in ATP and released through hydrolysis to ADP and Pi.
The video resource "ATP & Respiration: Crash Course Biology #7" 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.
Abiogenesis Paul Andersen describes how life could have formed on our planet through natural processes. The progression from monomers, to polymers, to protocells and finally to cells is described. The Miller-Urey experiment is described in detail as well as characteristics of the latest universal ancestor
This activity first asks the students to study the patterns of bird flight and understand that four main forces affect the flight abilities of a bird. They will study the shape, feather structure, and resulting differences in the pattern of flight. They will then look at several articles that feature newly designed planes and the birds that they are modeled after. The final component of this activity is to watch the Nature documentary, "Raptor Force" which chronicles the flight patterns of birds, how researchers study these animals, and what interests our military and aeronautical engineers about these natural adaptations. This activity serves as an extension to the biomimetics lesson. Although students will not be using this information in the design process for their desert resort, it provides interesting information pertaining to the current use of biomimetics in the field of aviation. Students may extend their design process by using this information to create a means of transportation to and from the resort if they chose to.
Paul Andersen explains important concepts that can not be explained by simple Mendelian genetics. He begins with a discussion of polygenic inheritance and uses a simulation on height to show how a bell shape curve of phenotypes is produced.
Tribal communities in southeastern Alaska are partnering with federal and state agencies to investigate increasing harmful algal bloomsevents that pose human health risks to subsistence harvesters.
Students learn how nanoparticles can be creatively used for medical diagnostic purposes. They learn about buckminsterfullerenes, more commonly known as buckyballs, and about the potential for these complex carbon molecules to deliver drugs and other treatments into the human body. They brainstorm methods to track buckyballs in the body, then build a buckyball from pipe cleaners with a fluorescent tag to model how nanoparticles might be labeled and detected for use in a living organism. As an extension, students research and select appropriate radioisotopes for different medical applications.
The AIBS Science Office works on issues related to biological research. Initiatives supported in the Science Office are generally of national concern and/or cross-disciplinary. A large share of the current activities surround distributed research and information networks as well as biological research facilities and infrastructure.
Paul Andersen explains the process of anaerobic respiration. This process involves glycolysis and fermentation and allows organisms to survive without oxygen. Lactic acid fermentation is used in animals and bacteria and uses lactate as an electron acceptor. Alcoholic fermentation used ethyl alcohol as an electron acceptor.
3-part lecture series given at Kwame Nkrumah University of Science and Technology about infections with Gram-negative obligate anaerobes
In this video Paul Andersen explains how scientists analyze data and evaluate evidence. He starts with a description of data and how it must be properly displayed. He then describes types of data in each of the four big ideas. He finally discusses a number of practice questions related to data analysis.
Paul Andersen steps you through eight types of animal behavior. He starts by defining ethology and explaining that behavior varies from innate to learned. He discusses each of the following with examples; instinct, fixed action pattern, imprinting, associative learning, trial and error learning, habituation, observational learning and insight.
The video resource "Animal Behavior - CrashCourse Biology #25" 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 introduces the concept of ethology and contrasts kinesis and taxis. He explains the importance of courtship rituals in fruit flies. He finally shows you how to use a choice chamber to study behavior in pill bugs.
The video resource "Animal Development: We're Just Tubes - Crash Course Biology #16" 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 briefly surveys members of the Domain Animalia. He begins with brief description of the phylogeny of animals. He then describes the characteristics of all animals, heterotrophy, multicellularity, motility and blastula. He describes eight invertebrates and vertebrates.
What is the Antibiotic Apocalypse? What is it all about? And how dangerous is it? The video "The Antibiotic Apocalypse Explained" is a resource included in the Biology topic made available from the Kurzgesagt open educational resource series.
Paul Andersen explains how aposematic coloration (or warning coloration) is used for protection in the natural world. He explains how bright colors can be caused by either sexual selection or a warning coloration to predators. He also explains how organisms can use this coloration to mimic other organisms with a similar pattern.
Archaea In this video Paul Andersen describes the defining characteristics of members in the domain archaebacteria. He starts with a brief description of the phylogeny of this group. He then describes the major characteristics on an archaea, such as differences in the phospholipids.

Life oPaul Andersen describes the defining characteristics of the domain Eubacteria. He begins with a quick description of the phylogeny of bacteria and horizontal gene transfer. He then surveys the structures of a bacteria; nucleoid region, capsule, pilli, cell wall with peptidoglycan, flagella.
Paul Andersen introduces the Punnett Square as a a powerful tool in genetic analysis. He tries to address major misconceptions that students have when use a Punnett Square. He gives a number of examples of monohybrid crosses and one example of a dihybrid cross.
Paul Andersen explains how the behavior of various organisms is shaped by natural selection. The action of phototropism and the timing of photoperiodism have both been shaped by the relative availability of light. Courtship in the bower bird determines the success of offspring.
