BIOL 109: Microbiology

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.

This video traces the evolution of genetic understanding, beginning with Mendel's foundational pea plant experiments, which birthed basic inheritance laws. It delves into complexities like co-dominance, incomplete dominance, and polygenic inheritance. Highlighting the integral role of DNA, it explains its structure and replication, shedding light on mutations. The narrative underscores the interplay of genes with the environment, introducing epigenetics and the myriad ways genes express, shaping

Discover the pivotal genetic change behind the evolution of tetrapod limbs, focusing on a specific shift in the Hox gene expression. Unravel the significance of this change and its role in the spatial organization of body parts.

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

Discover the intricate details of the pelvis anatomy as we analyze and correct misconceptions about its structure and components, using sketches for clarity.

Learn about the critical roles of the epiglottis and glottis in our respiratory and digestive systems. Understand how the epiglottis acts as a protective gate during swallowing, while the glottis facilitates sound production. Together, they ensure safe breathing and swallowing.
