IM 2200: Intro to Microbiology

Explore the indispensable role of decomposers in ecosystems. Understand their impact on nutrient cycling, energy flow, and ecological balance. Realize what Earth would face without these vital organisms.

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.

Explore the distinct characteristics of muscle tissues and their functions. Understand the differences between skeletal, cardiac, and smooth muscles. Get insights into the anatomy of striations, cell shapes, and nuclei.

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.

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.
