BIO 17275: Biology for the 21st Century

Discover the intricacies of lymphocytes, vital immune system cells, as we uncover where they develop the ability to effectively combat foreign invaders and the unique roles of T and B lymphocytes and NK cells.

Explore the differences in DNA, RNA, and protein synthesis between eukaryotic and prokaryotic cells. Understand the benefits of separation in eukaryotes and the efficiency of proximity in prokaryotes. Both systems reveal the ingenious ways cells adapt to their needs.

Discover the concept of adaptation in this video, where we evaluate four scenarios to determine which represents a heritable trait enhancing an organism's survival in its environment. Learn how the webbed feet of a duck exemplify a true adaptation, enabling it to thrive in its habitat.

Discover the essence of hydrostatic pressure and its significance in capillary beds, examining its relationship with colloid osmotic pressure and how it affects fluid movement in our circulatory system.

Explore the crucial concept of biodiversity and its significance. Learn about the various threats it faces, from pollution to habitat destruction. Emphasize the paramount threat: habitat alterations and their implications.

Venture into the intricate mechanisms of a eukaryotic cell as we clarify the conditions under which transcription begins. Discover the pivotal role of the promoter and the essential docking of transcription factors.
