CHEM 131: Principles of Chemistry

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.

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 vital roles of pharyngeal slits in lancelets and tunicates. Learn how these clefts aid in filter-feeding, capturing food particles, and evolve through different life stages.

Discover the distinctions and similarities between gymnosperms and angiosperms. Delve into their structural features, seed development processes, and pollen grain formation. Uncover why only angiosperms possess ovaries.

Deepen your understanding of glycolysis, a foundational cellular metabolism process. Grasp how glucose transforms into pyruvate or lactate, based on the presence of oxygen. A clear insight into this process aids in exercise science and disease research.

Discover the differences between hydrocarbons and other organic molecules. While hydrocarbons contain only carbon and hydrogen, other organic molecules integrate more elements and functional groups. This distinction leads to diverse chemical properties and vital biological functions.
