Homeostatic Disruptions

022 - Effect of Homeostatic Disruptions Paul Andersen explains how disruptions in homeostasis can affect biological systems at all levels. He uses the example of dehydration in animals to explain how disruptions at the cellular level can affect an organism. He also uses the example of the invasive brown tree snake in Guam to explain how disruptions can affect entire ecosystems. Do you speak another language?

Plant And Animal Defense

023 - Plant and Animal Defense Mechanisms 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. Do you speak another language? Help me translate my videos: www.bozemanscience.com/translations/ All of the ...

Development: Timing And Coordination

024 - Regulation of Timing and Coordination in Development - Paul Andersen explains how genes control the timing and coordination of embryo development. Seed germination initiates the discussion of cell differentiation. The SRY gene and genetic transplantation shows the importance of embryonic discussion. Cell deat is also an important part of development that is regulated by microRNA. HOX genes (a form of homeotic genes) is also discussed. Do you speak another language? Help me translate my ...

Mechanisms Of Timing And Control

025 - Mechanisms of Timing and Control Paul Andersen explains how organisms regulate timing and control. Phototropism and Photoperiodism allow plants to respond to light throughout the day and year. Circadian rhythms are used in all organisms (including animals) as an internal clock. Bacteria use quorum sensing to communicate the number of bacteria present. Do you speak another language?

Behavior And Natural Selection

026 - Behavior and Natural Selection Paul Andersen explains how the behavior of various organisms is shaped by natural selection. The action of phototropism and the timing of photoperiodism have both been shaped by the relative availability of light. Courtship in the bower bird determines the success of offspring. And finally pollination represents the combined success of the coevolution between insects and flowers. Do you speak another language? Help me translate my videos: www.bozemanscience.com/...

Dna And Rna - Part 2

027 - DNA and RNA - Part 2 Paul Andersen continues his description of DNA and RNA. He begins with the structure of DNA and RNA and moves into the process of DNA Replication. He also describes the central dogma of biology explaining how DNA is transcribed to mRNA and is finally translated into proteins. He also introduces genetic engineering and explains how transformation is used to create insulin. Do you speak another language? Help me translate ...
