Description
In this video lesson, Paul Andersen describes how free energy is used by organisms to grow, maintain order, and reproduce. A brief discussion of the first and second law of thermodynamics is also included. Disruptions in the amount of free energy can cause death and disruptions to popultaions, communities, and ecosystems.--Publisher.

In this video lesson, Paul Andersen explains how chemical change differs from physical change. In the laboratory, macroscopic observations are used to infer changes at the particulate level. Evidence for chemical change include gas production, change in temperature, change in odor, change in color, and formation of a precipitate.--Publisher.

Description
In this video lesson, Paul Andersen explains how the temperature is a measure of the average kinetic energy of particles in an object. The temperature is proportional to the average kinetic energy according to the Kelvin scale. At absolute zero, there is no molecular motion, and it is at 0K. The Maxwell-Boltzman distribution can be used to measure the average kinetic energy of the particles in a specific example.--Publisher.

In this video lesson, Paul Andersen explains how feedback loops allow living organisms to maintain homeostasis. He uses thermoregulation in mammals to explain how a negative feedback loop functions. He uses fruit ripening to explain how a positive feedback loop functions. He also explains what can happen when a feedback look is altered. Diabetes mellitus is caused by an alteration in the blood glucose feedback loop.--Publisher.

In this video lesson, Paul Andersen describes genetic drift as a mechanism for evolutionary change. A population genetics simulator is used to show the importance of large population size in neutralizing random change. The near extinction of the northern elephant is used as an example of the bottleneck effect. The high incidence of total colorblindness due to a typhoon that hit the small island of Pingelap is also 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...

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 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.

In this video lesson, Paul Andersen explains that entropy is simply the dispersion of matter or energy. He begins with a series of videos that show the natural direction of processes. According to the second law of thermodynamics, the entropy may never decrease in a closed system. In irreversible processes, the entropy will increase over time. The entropy will increase as volume increases, phases change, temperature increases, and as the moles of...

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 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.

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.
