BIOL 111: Introduction to Biology

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 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.

Explore the nature of compounds in chemistry, focusing on potassium chloride (KCl) and its dissociation. Understand the distinctions between salts, acids, bases, and buffers. Dive into the characteristic behaviors of each to identify the true nature of KCl.

Uncover why flamingos, genetically predisposed to white feathers, sport a pink hue. Dismissing influences like weather and DNA mutations, the mystery unravels with diet: the intake of carotenoids from their food which overrides their genetic blueprint

Explore the intricate world of phosphorylation cascades and their role in cellular signaling. Learn how protein kinases amplify external signals, guiding a cell's response. Decipher common misconceptions about these essential cellular processes.

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.
