BIOL 2101: Human Anatomy & Physiology 1 Lab

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.

Unravel the mysteries of food chain lengths by analyzing various factors. We spotlight the 10% rule in ecology, emphasizing how energy transfer inefficiencies mold ecosystem structures and functions.

Explore the crucial concept of biodiversity and its significance. Learn about the various threats it faces, from pollution to habitat destruction. Emphasize the paramount threat: habitat alterations and their implications.

Gain a clear understanding of chemical equilibrium, where reactant and product concentrations stay constant due to equal forward and reverse reaction rates. Dispel common misconceptions about equilibrium, such as concentration equality and reaction reversibility.

Discover the origins of specialized cells in embryonic development and learn about the three essential germ layers: ectoderm, mesoderm, and endoderm. Explore how these layers form the foundation for all multicellular life.

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.
