BIOL 1604: Animal Biology

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.

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.

Discover the body's innate ability to adapt to extreme cold conditions. Learn how the brain orchestrates warming responses like shivering. Grasp the concept of homeostasis in maintaining internal stability.

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

Discover the role of Okazaki fragments in DNA replication and the importance of DNA Ligase in ensuring their correct joining. Learn how a malfunction in this enzyme might disrupt the formation of continuous DNA strands on the lagging strand.
