BIOL 103: Human Biology

In this video we explore the unique characteristics that set animals apart from other organisms. We evaluate options like gastrulation multicellularity sexual reproduction and flagellated sperm. Conclusively we identify gastrulation as a truly unique process in animal embryonic development.

Dive into the biochemistry of haemoglobin, a pivotal protein in red blood cells. We assess key statements about its structure and function, clarifying common misconceptions.

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.

Discover the origins of specialized cells in embryonic development and learn about the three essential germ layers: ectoderm, mesoderm, and endoderm. Explore how these layers form the foundation for all multicellular life.

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.

Unpack the intricate processes within photosynthesis and identify which is most directly powered by light energy. Discover the critical role of chlorophyll in capturing solar power.
