BIOL 1911: Honors Introduction to Organismal Biology

Explore the indispensable role of decomposers in ecosystems. Understand their impact on nutrient cycling, energy flow, and ecological balance. Realize what Earth would face without these vital organisms.

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.

Discover the pivotal genetic change behind the evolution of tetrapod limbs, focusing on a specific shift in the Hox gene expression. Unravel the significance of this change and its role in the spatial organization of body parts.

Unpack the intricate process of sound transduction, from the initial vibrations in the ear to the transformation into neural signals. Learn about the vital roles of cochlea, basilar membrane, and hair cells in deciphering our auditory world. A comprehensive guide to the magic behind our hearing.

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.

Explore the effects of isotonic, hypertonic, and hypotonic solutions on plant and animal cells. Understand water movement, solute concentration dynamics, and the resulting cellular changes, including turgidity in plants and crenation or lysis in animals.
