Here's a chance to see if you can combine what you know to add up resistance in series AND in parallel. Rishi is a pediatric infectious disease physician and works at Khan Academy.

Dr. Mahadevan from Stanford School of Medicine explains adequacy for lateral cervical (neck) x-rays

This text was created by students in PHED 301 - Advanced Anatomy in the Sport, Health & Physical Education department at Vancouver Island University.

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 blooms—events that pose human health risks to subsistence harvesters.

Find out how Aldosterone and ADH cause changes in volume and osmolarity. Rishi is a pediatric infectious disease physician and works at Khan Academy.

See how Aldosterone effects the principal cells of the kidney to raise BP and lower potassium. Rishi is a pediatric infectious disease physician and works at Khan Academy.

See how Aldosterone acts on the alpha-intercalated cell to remove protons (acid) from the blood. Rishi is a pediatric infectious disease physician and works at Khan Academy.

In Florida's humid climate, strawberry growers are in a constant battle with two kinds of fruit rot. Using a decision support system, they can save money by spraying fields only when the plant diseases are a threat.

This resource is the manual for "Allele A1" Software. AlleleA1 simulates evolution at a single locus in an ideal population of imaginary organisms. The user enters values for parameters controlling selection, mutation, migration, genetic drift, and inbreeding. As the simulation runs, the software plots a graph showing the frequency of allele A1 over time. The resource, "Allele A1 Manual (pdf)" within "Lesson 03 Population Genetics and the Evolution of Resistance - Elaboration" is a part of Unit 06 Population Genetics and the Evolution of Resistance included in Agriscience & Biotechnology, Ag Bio - Course 2.

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 introduces Anatomy and Physiology in this podcast. He starts by describing how the form of an object fits the function. He then explains the themes of homeostasis and hierarchy. He describes the four major types of tissues; epithelial, muscle, nervous and connective.

Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors. The book is organized by body system and covers standard scope and sequence requirements. Its lucid text, strategically constructed art, career features, and links to external learning tools address the critical teaching and learning challenges in the course. The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams.

Includes the study of the gross and microscopic structure of the systems of the human body with special emphasis on the relationship between structure and function. Integrates anatomy and physiology of cells, tissues, organs, the systems of the human body, and mechanisms responsible for homeostasis.

Includes sections on the Endocrine System, the Cardiovascular System, the Lymphatic and Immune System, the Respiratory System, the Digestive System, Nutrition, the Urinary System, the Reproductive System, and Development and Inheritance.

This Open Course is an adaptation of OpenStax Anatomy and Physiology and was created under a Round Nine ALG Textbook Transformation Grant.

Topics covered include:

Chemical Organization
