BIOL 1111: Introduction to Biology I

Explore active and passive transport and understand how ion pumps and phagocytosis fit in. Discover endocytosis as an active transport where cells engulf particles. Differentiate between active transport mechanisms and passive methods like facilitated diffusion.

Get acquainted with the intricate details of the vertebrae, from typical structure components to the unique traits of cervical, thoracic, and lumbar vertebrae. Enhance your grasp of the spinal column's sophistication and importance in human anatomy.

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.

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.

Explore the fascinating intersection of human and prokaryotic genetics revealing that both contain about 1000 shared genes despite their complexity difference. The video explains how this common genetic heritage can be traced back to a universal ancestor covering the essential functions these genes perform like metabolism and DNA replication.
