BIOB 170: Principles Biological Diversity

Explore the definitions of tissue, organ, and organ system. Understand the distinctions and interconnectedness between these components. Get an overview of the human body's eleven major organ systems and their functions.

Unpack the concept of Restriction Fragment Length Polymorphism (RFLP), exploring the significance of DNA fragment variations. Learn how restriction enzymes act as molecular scissors, leading to insights into genetic disorders, biodiversity, and more.

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
