BIO 26935: Biology for the 21st Century

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.

Discover the differences between hydrocarbons and other organic molecules. While hydrocarbons contain only carbon and hydrogen, other organic molecules integrate more elements and functional groups. This distinction leads to diverse chemical properties and vital biological functions.

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 concept of adaptation in this video, where we evaluate four scenarios to determine which represents a heritable trait enhancing an organism's survival in its environment. Learn how the webbed feet of a duck exemplify a true adaptation, enabling it to thrive in its habitat.

Discover the roles of sensory, interneurons, and motor neurons in the nervous system. These specialized cells transmit, process, and execute commands, orchestrating our responses. Experience the seamless coordination that enables us to interact with our environment.

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.
