BIOL 160: Biological Sciences I

Explore the world of microbiology in this video as we investigate the processes that lead to genetic variation in bacterial populations. Learn about transduction, transformation, conjugation, and mutation, and discover why meiosis, a process occurring in sexually reproducing organisms, is not a source of genetic variation in bacteria.

Explore the intricate components of the endomembrane system within a cell. Identify which structures belong to this system and which do not, with a specific focus on the unique role of the chloroplast.

In this video, we explore the crucial role of the cytoplasm in a cell and its division. By drawing parallels to intriguing concepts like telekinesis, we shed light on vital processes like karyokinesis and cytokinesis. By the end, we unveil cytokinesis as the primary method for plant cell cytoplasm division.

Explore the critical role of phospholipids in forming cell membranes across various organisms. Understand their unique amphipathic properties and their influence on cellular processes, from transport to signaling.

Discover the fundamentals of the respiratory system and the primary muscle behind inspiration. This video breaks down the physiological process of breathing, the key role of the diaphragm, and why other muscles don't initiate breathing.
