BIOL 111: General College Biology

Explore the indispensable role of decomposers in ecosystems. Understand their impact on nutrient cycling, energy flow, and ecological balance. Realize what Earth would face without these vital organisms.

Discover the intricate world of phylogenetic systematics, a method revealing life's diverse connections. Dive into the tree-like structure representing evolutionary relationships. Unravel how shared traits help sketch the ever-evolving story of life

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.

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

Discover the fundamentals of the respiratory system and the primary muscle behind inspiration. This video breaks down the physiological process of breathing, the key role of the diaphragm, and why other muscles don't initiate breathing.

Learn about mouse genetics and the implications of dominant and recessive genes on coat color. We'll use a Punnett square to predict offspring coat patterns by crossing two heterozygous mice. Learn how phenotype ratios like 9 Agouti: 4 white: 3 black help us understand genetic outcomes.
