BIOL 998: Doctoral Comprehensive Examination (w/Classes)

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.

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 intricacies of nucleic acids, the macromolecules essential to life. Understand the roles of DNA and RNA, and delve into the structure of nucleotides—the fundamental building blocks of these crucial biomolecules.

Explore stromatolites, the oldest indicators of life on Earth formed by microbial actions. Understand their presence in shallow marine environments and their connection to early eukaryotic life.

Explore the fascinating process of protein digestion, debunking misconceptions about where it starts. Discover the roles of enzymes like pepsin and HCl in breaking down proteins in the stomach.

Get insights into the role of lysosomes in different cell types. Find out which cell is the ideal choice for studying these powerful digestive organelles and why.
