EEB 101: Intro to Biological Sciences

Explore the fascinating world of vertebrates and tunicates in this video answer. Learn about their shared anatomical features including notochords and dorsal hollow nerve cords that reveal their closely linked evolutionary history

Explore the pivotal role of enhancers in gene expression as we dissect their function and interaction with transcription factors. Gain insights into how they crucially influence the transcriptional control of genes.

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.

Explore the role of human placental lactogen (hPL) in this informative video. Learn how hPL prepares the breasts for lactation, debunking other hypotheses about its functions in nourishing the placenta or regulating the menstrual cycle. Discover the primary function of this remarkable placental hormone.

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.
