BIOL 106: General Biology

Explore the hierarchy of biological structures to identify the smallest independent unit of life. This video assesses options from organelles to organs, elucidating the pivotal role of the cell in life's tapestry.

Discover the precise organization of thin and thick filaments in muscle cells as we debunk misconceptions and highlight the vital role of sarcomeres in muscle contraction.

Uncover the fundamentals of human muscle contraction and anatomy in this lesson. Highlighting the distinct roles of muscle origin and insertion we clarify their functions in movement. Learn why the muscle origin is the cornerstone of stability during contraction anchoring our body mechanics.

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.

Learn about the unique adaptability of facultatively anaerobic cells in different oxygen conditions. Discover the outcome of an experiment comparing their growth in aerobic and anaerobic environments. Grasp the resilience of these cells and their growth mechanisms.

Explore how viruses replicate and the various ways in which new viruses emerge. Understand the importance of mutation, cross-species transmission, and the significance of wider spread in host species for disease control strategies.
