BIOL 017: Anatomy and Physiology 1

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 stromatolites, the oldest indicators of life on Earth formed by microbial actions. Understand their presence in shallow marine environments and their connection to early eukaryotic life.

Discover the unique adaptations of C4 and CAM plants in photosynthesis. Understand their evolved strategies to fix carbon efficiently in challenging environments. Dive into nature's remarkable mechanisms of survival and adaptation.

Explore the world of Spirillum bacteria, their spiral shape, and their distinct features. Contrast them with Spirochetes, highlighting differences in flagella and structure. Understand key characteristics that set Spirillum apart from other bacteria.

Explore the significance of tracking same-age cohorts in population ecology. Learn how it aids in understanding birth and death rates, predicting population trends, and uncover the reasons behind this crucial ecological research practice.
