BIOL 2601: General Biology: Molecules and Cells

Explore the fascinating world of vertebrates and tunicates in this video answer. Learn about their shared anatomical features including notochords and dorsal hollow nerve cords that reveal their closely linked evolutionary history

Explore the distinct approaches of bioremediation and biological augmentation in managing environmental issues. Learn how organisms are utilized for pollutant degradation or enhancing ecological functions to mitigate environmental degradation.

Learn why lipid-soluble signaling molecules like aldosterone only impact specific target cells. We discuss four theories and reveal that intracellular receptors present only in target cells are the key. This video demystifies the unique mechanism behind aldosterone's selective action.

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.

In this video we explore the unique characteristics that set animals apart from other organisms. We evaluate options like gastrulation multicellularity sexual reproduction and flagellated sperm. Conclusively we identify gastrulation as a truly unique process in animal embryonic development.

Explore the key concepts that might illustrate the unity among all organisms including emergent properties descent with modification and natural selection. Understand why the structure and function of DNA ultimately stand as the best example of this unity
