BIOL 105: Human Biology

This video provides a comprehensive explanation of mucous and serous membranes, defining their characteristics and addressing statements about their epithelial types, functions, and exceptions.

Explore the key concepts that might illustrate the unity among all organisms including emergent properties descent with modification and natural selection. Understand why the structure and function of DNA ultimately stand as the best example of this unity

Unravel the intricacies of a eukaryotic cell, its DNA structure, and the proteins that aid its function. Delve into the roles of cohesin, condensin, and histones, and discover the difference between chromatin, nucleosomes, and sister chromatids. Gain clarity on the pivotal structure ensuring successful cell division.

Uncover the vital role of the kidneys in blood filtration and electrolyte balance. Understand the significance of the glomerulus, Bowman's capsule, and renal structures in the filtration process. Grasp the journey of filtrate as it becomes urine within the renal system.

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 concept of semiconservative DNA replication, where each new DNA molecule retains one original strand. Understand the significance of this mechanism in ensuring accurate genetic information transfer across cell generations.
