BIOL 3400: Cell Biology

Discover the concept of adaptation in this video, where we evaluate four scenarios to determine which represents a heritable trait enhancing an organism's survival in its environment. Learn how the webbed feet of a duck exemplify a true adaptation, enabling it to thrive in its habitat.

Explore the influence of atmospheric pressure in our body's functions, particularly its essential role in pulmonary ventilation or the breathing process.

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.

Explore Fluorine's electron configuration and its impact on chemical reactivity. Learn about electron shells, orbitals, and the quest for a complete valence shell.

Discover which metabolic pathway is the heavyweight champion of ATP production. We'll evaluate contenders like lactic acid fermentation, the Krebs cycle, and more to determine the top ATP generator.
