BIOL 121: Principles of Biology

Discover how filtration pressure is calculated within our bodies. Explore various options from adding capillary pressures to understanding lymphatic vessel roles. Grasp essential physiology principles as we highlight the accurate method.

In cell biology, the "driving ion" is a pivotal concept. It refers to ions moving from areas of high to low concentration, generating energy for various cellular transport processes. This gradient is crucial for nutrient uptake and waste elimination. Multiple processes involve a driving ion, including facilitated diffusion, symport transport, primary active transport pumps, and cotransport. Facilitated diffusion aids molecule movement along their gradient, while symport moves multiple substance

Explore the world of spontaneous reactions, focusing on cellular respiration. Learn how our cells convert glucose into energy-rich ATP, driving vital life functions.

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 fascinating realm of organic chemistry and its emphasis on carbon compounds. Understand how organic molecules, pivotal to life, are intricately composed. Gain insight into the properties and relationships that make these compounds essential.

Discover the origins of specialized cells in embryonic development and learn about the three essential germ layers: ectoderm, mesoderm, and endoderm. Explore how these layers form the foundation for all multicellular life.
