The video resource "Ecology - Rules for Living on Earth: Crash Course Biology #40" 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 how ecosystems change over time. He starts by explaining how global climate change will impacts ecosystems around the planet. He then discusses how continental drift created climatic changes that impacted mammal species.
The video resource "Ecosystem Ecology: Links in the Chain - Crash Course Ecology #7" is included in the "Ecology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.
Paul Andersen explains how ecosystems interact with biotic and abiotic factors. He explains and gives examples of food chains and food webs. He shows how limiting factors eventually leads to logistic growth. Real data from Yellowstone Park is used to show how populations interact.
Paul Andersen explains how changes in the signal transduction pathway can affect organisms. He begins with a brief discussion of the tetrodotoxin produced by the California Newt. He then explains how anthrax affects adenylate cyclase and thereby shuts down the signal transduction pathway.
Overview of the Electron Transport Chain
This "Embryonic Stem Cells and Somatic Cell Nuclear Transfer (extended version)" 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.
How can many stupid things combine to form smart things? How can proteins become living cells? How become lots of ants a colony? What is emergence? The video "Emergence - How Stupid Things Become Smart Together" is a resource included in the Biology topic made available from the Kurzgesagt open educational resource series.
Paul Andersen explains how eukaryotic cells were formed through a process of endosymbiosis. He describes how aerobic bacteria became mitochondria and cyanobacteria became chloroplasts. He mentions an example of symbiosis that occurs today and mentions the importance of Dr. Lynn Margulis in the development of this modern theory.
This biomimetic engineering challenge introduces students to the fields of nanotechnology and biomimicry. Students explore how to modify surfaces such as wood or cotton fabric at the nanoscale. They create specialized materials with features such as waterproofing and stain resistance. The challenge starts with student teams identifying an intended user and developing scenarios for using their developed material. Students then design and create their specialized material using everyday materials. Each students test each design under specific testing constraints to determine the hydrophobicity of the material. After testing, teams iterate ways to improve their self-cleaning superhydrophobic modification technique for their design. After iterating and testing their designs, students present their final product and results to the class.
Labs in this book supplement the information gained in lecture, as well as providing some perspective and experience with hands-on applications of ideas in pest management. The labs are presented in week-by-week order, so the pre-labs and reading for week 1 are labeled “Pre-Lab 1” and “Week 1 Reading”.
Pre-Labs are assignments to be done before lab meets, and will be due at the beginning of Lab. Complete the labs using your textbook, web resources, or the reading assigned for the week.
Readings are short 1-3 page “chapters” covering background topics pertinent to the upcoming lab, particular groups of insects/arthropods, or methods used in Pest Management. This should be read before coming to Lab each week.
Lab Assignments need to be printed and brought to class so that they can be completed as a group in Lab. It is sometimes helpful to read through the assignment ahead of time to get an idea of the subject matter for the week.
This open textbook covers the most salient environmental issues, from a biological perspective. The text is designed for an introductory-level college science course. Topics include the fundamentals of ecology, biodiversity, pollution, climate change, food production, and human population growth.
Lecture slides for each chapter are available from https://drive.google.com/drive/folders/119oj6XXHnQMpwu_rCgczDFrZPMbqGN8W
This college-level open textbook covers the most salient environmental issues from a biological perspective.
Paul Andersen explains how living organisms exchange matter with the environment. The importance of the surface area to volume ratio is emphasized using a simple mathematical model. The essential chemicals for life; water, carbon, nitrogen and phosphorus are described. Each of these elements are vital to the four major macromolecules.
Paul Andersen starts with a brief description of enzymes and substrates. He then explains how you can measure the rate of an enzyme mediated reaction. Catalase from yeast is used to break hydrogen peroxide down into water and oxygen. He also explains how temperature and pH could affect the rate of a reaction.
Paul Andersen explains how enzymes are used to break down substrates. The correct shape of the active site allows a key/lock fit between the enzyme and the substrate. The enzyme catalase is used to break down hydrogen peroxide. The importance of cofactors and coenzymes is emphasized.
Paul Andersen describes three main characteristics of life that are conserved in all organisms on the planet. The universal genetic code, the central dogma of biology, and shared metabolic pathways give us details of the original universal ancestor.
Paul Andersen discusses the defining characteristics of the members of Domain Eukarya. He starts with a brief description of the phylogeny of life on earth. He then discusses the major characteristics of eukaryotic cells. He explains how eukaryotic cells evolved from prokaryotic cells using endosymbiosis and infolding.
Hank tells us about the city of Eukaryopolis - the animal cell that is responsible for all the cool things that happen in our bodies.
The video resource "Eukaryopolis - The City of Animal Cells: Crash Course Biology #4" 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.
