BIOL 242: Diversity of Life

Explore the influential Three-Domain System of classification, introduced by Carl Woese in 1978. Discover how it categorizes life into Bacteria, Archaea, and Eukarya based on distinctive cellular structures. Learn about the characteristics of each domain, from prokaryotic Bacteria and Archaea to the rich diversity within Eukarya, encompassing Protists, Fungi, Plants, Animals, and the unique world of viruses.

Discover the differences between hydrocarbons and other organic molecules. While hydrocarbons contain only carbon and hydrogen, other organic molecules integrate more elements and functional groups. This distinction leads to diverse chemical properties and vital biological functions.

Unlock the language of genetic history with our guide to understanding pedigrees and their symbols. Learn how to interpret squares circles and lines to track inheritance patterns for traits and diseases.

Explore the intricate eukaryotic cell structure, from the protective plasma membrane to the vital organelles. Learn how DNA, ribosomes, and the cytoskeleton play pivotal roles in cellular function. Dive deep into the world of mitochondria, ER, and the Golgi apparatus.

Learn about mouse genetics and the implications of dominant and recessive genes on coat color. We'll use a Punnett square to predict offspring coat patterns by crossing two heterozygous mice. Learn how phenotype ratios like 9 Agouti: 4 white: 3 black help us understand genetic outcomes.

Discover the fascinating science behind table salt's unique characteristics that arise from the bond between sodium and chloride atoms. Explore topics like its unique taste, solubility in water, and ability to conduct electricity. Learn how the combination of sodium and chloride creates properties neither element possesses on its own.
