In this video Paul Andersen explains the importance of oxygen in accepting electrons. He begins with a brief description of combustion. He then explains the role of oxygen in aerobic cellular respiration.
Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane.
The video resource "In Da Club - Membranes & Transport: Crash Course Biology #5" 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.

Overview of the inflammatory response
Paul Andersen explains how organisms use information to communicate with each other. Signals are used by bees doing the waggle dance to communicate the location of flowers. Territorial markings are used by wolves to establish territory. Complex courtship rituals are used by sage grouse to ensure mating success.
This Instructor’s Guide contains the brief outlines of Chapters 12-21 as found in Concepts of Biology, though some underwent revision. Also, instructors will find detailed outlines of the text for use in lecturing, as well as structured outlines that may be used by students to take notes while reading the chapter or during lecture. All outlines are derived from the OpenStax text. Additionally, study guides that contain a variety of questions are provided for students.
Introduction to cellular respiration, glycolysis, the Kreb's Cycle, and the electron transport chain
Introduction to evolution, variation in a population and natural selection
Heredity and Classical Genetics. Dominant and recessive traits. Heterozygous and homozygous genotypes.

Students learn about the current applications and limitations of 3D bioprinting, as well as its amazing future potential. This lesson, and its fun associated activity, provides a unique way to review and explore concepts such as differing cell functions, multicellular organism complexity, and engineering design steps. As introduced through a PowerPoint® presentation, students learn about three different types of bioprinters, with a focus on the extrusion model. Then they learn the basics of tissue engineering and the steps to design printed tissues. This background information prepares students to conduct the associated activity in which they use mock-3D bioprinters composed of a desktop setup that uses bags of icing to “bioprint” replacement skin, bone and muscle for a fictitious trauma patient, Bill. A pre/post-quiz is also provided.
The resource , ''Isometric Paper (pdf)'' included in "Lesson 2 Engineering Graphics, Lesson 3 Engineering Graphics" is a part of "Unit 03 Cardiovascular and Respiratory Systems, Unit 05 Urinary and Reproductive Systems" included in Health & Life Sciences HLS - Course 2.
Through two lessons and five activities, students explore the structure and function of cell membranes. Specific transport functions, including active and passive transport, are presented. In the legacy cycle tradition, students are motivated with a Grand Challenge question. As they study the ingress and egress of particles through membranes, students learn about quantum dots and biotechnology through the concept of intracellular engineering.
Overview of how the nephrons in the kidney filter blood and reabsorb water and other molecules.
This comprehensive module explores common laboratory experiments for microbiology, including microbiological stains (e.g. Gram stains), assessing the accuracy of diagnostic tests, measuring antibody response to infection, and Detection of microbial antigens, and nucleic acid amplification (e.g. Polymerase Chain Reaction).
