Paul Andersen explains the three types of muscle found in humans; striated, smooth and cardiac muscle. He explains how actin and myosin interact to contract the sarcomere in a muscle. The sliding filament theory explains how ATP and calcium are used to contract the z disks.
Paul Andersen describes the major mutations found in the living world. He starts with an analogy comparing the information in DNA with the information in a recipe. Changes in the DNA can result in changes to the protein, like changes in the recipe can result in changes in the food.
How myosin and actin interact to produce mechanical force.
This online video briefly shows glacial loss in North and South America between 2003 and 2010. The resource, "NASA Goodbye Glaciers" included in "Lesson 3 Black Ice" is a part of "Unit 03 Challenges to Safe Operating Space" included in Energy & Sustainability ES - Course 2.
In this survey text, directed at those not majoring in biology, we dispel the assumption that a little learning is a dangerous thing. We hope that by skimming the surface of a very deep subject, biology, we may inspire you to drink more deeply and make more informed choices relating to your health, the environment, politics, and the greatest subject that are all of us are entwined in, life itself.
The National Association of Biology Teachers (NABT) is "the leader in life science education." To date, more than 9,000 educators have joined NABT to share experiences and expertise with colleagues from around the globe; keep up with trends and developments in the field; and grow professionally.
Natural Resources Biometrics begins with a review of descriptive statistics, estimation, and hypothesis testing. The following chapters cover one- and two-way analysis of variance (ANOVA), including multiple comparison methods and interaction assessment, with a strong emphasis on application and interpretation. Simple and multiple linear regressions in a natural resource setting are covered in the next chapters, focusing on correlation, model fitting, residual analysis, and confidence and prediction intervals. The final chapters cover growth and yield models, volume and biomass equations, site index curves, competition indices, importance values, and measures of species diversity, association, and community similarity.
Hank guides us through the process of natural selection, the key mechanism of evolution.
Paul Andersen explains how natural selection is a major mechanism in evolution. The video begins with a discussion of Charles Darwin and the details of natural selection. The data of the peppered moth during the industrial revolution is used to show the process of adaptation.
The video resource "Natural Selection - Crash Course Biology #14" 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.
How the "Owl Butterfly" may have gotten the spot on its wings.
Hank begins a series of videos on organ systems with a look at the nervous system and all of the things that it is responsible for in the body.
Paul Andersen begins this podcast with a discussion of brain lateralization and gives a brief demonstration of tests that were performed on split-brain individuals. He then discusses the major parts of a neuron and explains how action potentials are generated using voltage-gated ion channels.
The video resource "The Nervous System - CrashCourse Biology #26" 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.
