BIOL 2000: Biology Today

Grasp the fundamentals of how neurons transmit electrical signals through action potentials. Understand the crucial role of myelination and fiber diameter in efficient nerve impulse conduction. Dive into the comparisons of different nerve fiber types and their properties.

Discover the intricate details of the pelvis anatomy as we analyze and correct misconceptions about its structure and components, using sketches for clarity.

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 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.
