BIOL 3096: Cell Structure and Function

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 how our brain interprets the scent of smoke differently based on context. Compare reactions in an open campfire setting versus an enclosed residence hall. Understand the underlying mechanisms of olfactory fatigue and context-driven alarm responses.

Discover the Oparin-Haldane hypothesis detailing Earth's primordial conditions and the potential birth of life. Learn about the abiotic synthesis of organic molecules, the rise of protobionts, and the evolution to the first true cells.

Explore active and passive transport and understand how ion pumps and phagocytosis fit in. Discover endocytosis as an active transport where cells engulf particles. Differentiate between active transport mechanisms and passive methods like facilitated diffusion.

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.

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.
