BIOL 1050: Biology & Environmnt

Unlock the basics of the anatomical position, a crucial standard in medical and anatomical studies. This video clarifies the key differences among prone, supine, and standing positions and why they're not the anatomical position.

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 world of spontaneous reactions, focusing on cellular respiration. Learn how our cells convert glucose into energy-rich ATP, driving vital life functions.

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.

Unravel the origins of blood cell types as we differentiate between myeloid and lymphoid stem cells, highlighting the unique lineage of platelets, B cells, and Natural Killer cells.

Explore the similarities and differences between the circulatory systems of amphibians and humans. Understand the distinctions in heart chambers, blood pressure, and where these two species align in their circulatory features.
