BSC 117: Biology II

Learn about male pattern baldness as we break down the science behind shrinking hair follicles and their effects on hair thinning. Learn why bald men still have hair follicles and what happens to them over time. Ideal for anyone keen to understand the biology of hair loss.

Dive into the biochemistry of haemoglobin, a pivotal protein in red blood cells. We assess key statements about its structure and function, clarifying common misconceptions.

This data-driven video examines the difference in nucleotide replication rates between prokaryotes and eukaryotes, providing insights into the factors affecting their speed. It concludes that prokaryotes outpace eukaryotes, replicating nucleotides approximately ten times faster, and explores the contributing factors behind this difference.

Explore the concept of semiconservative DNA replication, where each new DNA molecule retains one original strand. Understand the significance of this mechanism in ensuring accurate genetic information transfer across cell generations.

Discover why most cells are unable to utilize heat for work by exploring the principles of cellular thermodynamics. Learn how heat, as a form of kinetic energy, relates to cellular processes and why uniform temperature distribution within cells hinders their ability to harness heat effectively. Uncover the key factors that determine why cells can't perform work using heat.

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.
