BIOL 122: General Biology 2

Explore the secrets of fossilization in sedimentary rocks. Uncover how these rocks, like nature's archives, preserve the history of life on Earth over billions of years. Delve into the unique processes that create these historical records.

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.

Explore what makes each element unique by focusing on the atomic components: protons neutrons and electrons. Learn why the number of protons known as the atomic number is the defining characteristic for each element's properties. Understand how protons set elements apart even as neutrons and electrons also play important roles.

Discover the dynamic nature of the cell's lipid bilayer. Delve into the roles of unsaturated and saturated phospholipids in membrane fluidity. Understand temperature's influence on this vital cellular component.

Explore the pivotal role of enhancers in gene expression as we dissect their function and interaction with transcription factors. Gain insights into how they crucially influence the transcriptional control of genes.

Explore the groundbreaking heterotroph hypothesis by Alexander Oparin. This video outlines how the first organisms likely consumed pre-existing organic matter reshaping how we think about the origins of life and evolution
