BIO 26935: Biology for the 21st Century

Learn how bioremediation works to treat contaminated environments and how microbes can help clean up pollutants. We evaluate multiple scenarios zeroing in on oil-degrading bacteria as a prime example of the process.

Explore how viruses replicate and the various ways in which new viruses emerge. Understand the importance of mutation, cross-species transmission, and the significance of wider spread in host species for disease control strategies.

Explore the intricate eukaryotic cell structure, from the protective plasma membrane to the vital organelles. Learn how DNA, ribosomes, and the cytoskeleton play pivotal roles in cellular function. Dive deep into the world of mitochondria, ER, and the Golgi apparatus.

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 mechanics of voltage-gated Na+ channels and their role in neuron activity. This video breaks down key neuronal terms like resting potential and threshold to explain precisely when these channels open. You'll come away understanding that voltage-gated Na+ channels open at the threshold state initiating an action potential.

Explore the intricate components of the endomembrane system within a cell. Identify which structures belong to this system and which do not, with a specific focus on the unique role of the chloroplast.
