Biology essentials volume 012
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 course you will learn why it's important to adjust your organizational structure to implement AWS Cloud Financial Management (CFM). You will learn about new responsibilities that must be developed and owned within the finance organization as you use or continue to use AWS.--Publisher.
9) Biodiversity
Series
Biology essentials volume 055
Description
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.
11) Momentum
Description
"Paul Andersen will first define momentum as the product of an object's mass and velocity. He will then demonstrate how a net force acting on an object will change the momentum in the direction of the force. Several problems will be included."--
13) pH and buffers
Series
Chemistry essentials volume 069
Description
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.

Chemistry essentials volume 038
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...

Biology essentials volume 013
Description
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.
16) Gene regulation
Series
Biology essentials volume 031
Description
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.
