Description
"The Town That Said, Hell No!" is the story of a rural Colorado community under siege by AMAX, a huge international mining corporation. This powerful company was accustomed to getting its way, but it met its match in the late 1970s and early 1980s when it tried to overrun a unique and undaunted adversary.
Crested Butte was no ordinary town. Hemmed in by high mountains in the heart of the Central Rockies of Colorado, summers at 9,000 feet are idyllic,...

In this video lesson, Paul Andersen explains simple Mendelian genetics. He begins with a brief introduction of Gregor Mendel and his laws of segregation and independent assortment. He then presents a number of simple genetics problems along with their answers. He also explains how advances in genetic knowledge may lead to ethical and privacy concerns.--Publisher.

In this video lesson, Paul Andersen explains how radioactive nuclei can decay by releasing an alpha, beta, or gamma particle. The exact moment of decay for each nucleus cannot be determined, but probability is useful in predicting the half-life. The half-life is the amount of time required for half of the radioactive nucleus to decay, and it depends on the decay constant. Several examples of decay and several half-lives are included.--Publisher.

Description
In this video lesson, Paul Andersen explains that elementary reactions are steps within a larger reaction mechanism. Colliding molecules require sufficient energy and proper orientation to break bonds and form new bonds. A unimolecular reaction mechanism requires one type of reactant and is a first-order reaction. A bimolecular reactions requires two molecules colliding and is a second-order reaction. Termolecular reactions are rare but are the colliding...

Description
In this video lesson, 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 lead to logistic growth. Real data from Yellowstone Park is used to show how populations interact. He ends the lesson by showing how human impacts can eventually lead to changes within an ecosystem.--Publisher.

In this video lesson, Paul Andersen explains how the cell cycle is used to create new cells. The creation of identical diploid daughter cells, through mitosis, is described. The creation of unique haploid daughter cells through meiosis is also described. The importance of cyclin and cyclin dependent kinases to regulate the cell cycle is included.--Publisher.

In this video lesson, Paul Andersen explains the differences between a system and an object. Depending on the scale, it often times easiest to view a system as an object if the constituent parts aren't relevant to the question being asked. He also explains how the simplest objects are the fundamental particles of matter.--Publisher.

In this video lesson, Paul Andersen explains how genes are regulated in both prokaryotes and eukaryotes. He begins with a description of lac and trp operons and how they are used by bacteria in both positive and negative response. He also explains the importance of transcription factors in eukaryotic gene expression.--Publisher.

In this video lesson, Paul Andersen details the processes of photosynthesis and respiration. Autotrophs use the light reactions and the Calvin cycle to convert energy from the Sun into sugars. Autotrophs and heterotrophs use cellular respiration to convert this sugar into ATP. Both chemosynthesis and fermentation are discussed. The evolution of photosynthesis is also discussed.--Publisher.

In this video lesson, 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. He also explains how eukaryotic cells gained complexity through infolding of the cell membrane and endosymbiosis.--Publisher.

In this video lesson, Paul Andersen explains how buffer solutions maintain pH in a solution. A buffer solution is made up of a weak acid and its conjugate base. As strong acids or bases are added, the pH remains stable. A good buffer solution has a pKa value equivalent to the pH and equal amounts of the weak acid and the conjugate base.--Publisher.

In this video lesson, Paul Andersen explains the importance of biodiversity. He starts by describing how biodiversity can be species, genetic, or ecosystem diversity. He explains the importance of keystone species in an environment and gives two examples: the jaguar and the sea otter. He finishes with a quote from the father of biodiversity, E.O. Wilson.--Publisher.

Description
In this video lesson, Paul Andersen explains how the center of mass of an object represents the average position of matter in an object. The center of mass of a system is a combination of all the objects within the system. As long as no external torque is applied to the system, the center of mass will be conserved.--Publisher.

In this video lesson, Paul Andersen explains how Newton's Third Law applies to all objects. When an object applies a force to another object (Action), an equal and opposite force (Reaction) is applied to the original object. Several scenarios are described to show these action-reaction pairs. Free-body diagrams are used to describe all of the external forces from these interactions.--Publisher.

In this video lesson, Paul Andersen describes how plants and animals defend themselves against pathogens. He begins by discussing the hypersensitive response in plants as a nonspecific form of immune response. He then discusses both the humoral and cell-mediated immune response in mammals. A brief discussion of the chicken pox, small pox, and HIV is included.--Publisher.
