BIO 1421004: Modern Biology II

Discover the intricacies of lymphocytes, vital immune system cells, as we uncover where they develop the ability to effectively combat foreign invaders and the unique roles of T and B lymphocytes and NK cells.

Learn about the role of Erythropoietin (EPO), a natural kidney hormone, in controlling red blood cell production and oxygen transport. Discover how athletes misuse synthetic EPO for performance enhancement, despite the associated health risks.

Unpack the process of biological magnification in the food chain and learn why consuming foods from lower trophic levels minimizes toxin exposure. Grasp the implications of human-induced pollutants and the benefits of dietary diversity.

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.

Unravel the mysteries of food chain lengths by analyzing various factors. We spotlight the 10% rule in ecology, emphasizing how energy transfer inefficiencies mold ecosystem structures and functions.

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.
