BIOL 120: The Science of Life.

Explore the profound impact of oceans on the biosphere in this video. Discover how oceans contribute to oxygen production, carbon dioxide absorption, and climate moderation, while also uncovering their limitations in regulating the pH of freshwater biomes and terrestrial groundwater.

Explore the influential Three-Domain System of classification, introduced by Carl Woese in 1978. Discover how it categorizes life into Bacteria, Archaea, and Eukarya based on distinctive cellular structures. Learn about the characteristics of each domain, from prokaryotic Bacteria and Archaea to the rich diversity within Eukarya, encompassing Protists, Fungi, Plants, Animals, and the unique world of viruses.

Learn about the role of Erythropoietin (EPO), a natural kidney hormone, in controlling red blood cell production and oxygen transport. Discover how athletes misuse synthetic EPO for performance enhancement, despite the associated health risks.

Learn how bioremediation works to treat contaminated environments and how microbes can help clean up pollutants. We evaluate multiple scenarios zeroing in on oil-degrading bacteria as a prime example of the process.

Explore the concept of semiconservative DNA replication, where each new DNA molecule retains one original strand. Understand the significance of this mechanism in ensuring accurate genetic information transfer across cell generations.

Explore the distinct differences between eukaryotic and prokaryotic chromosomes. Understand their structures, organization, size, and cellular locations. Grasp how these genetic units underscore life's incredible diversity.
