Biology- Organisms and Ecosystems (BG101)
Version 1 and 2: 41 hours.
Version 1: September 2017 – January 2023. Version 2: February 2023 - Present.
Version 1 and 2: Upon successful completion of the course, students will be able to: explore the evolution and natural selection of species on Earth; analyze speciation and demonstrate how adaptation has occurred over the years; explore the fossils of the Earth and determine what caused extinction in certain species; recognize the Hardy-Weinberg Principle and examine how it is applied in nature; identify the effects of genetic drift and gene flow; differentiate effects of non-random mating and creation of subspecies; examine the phylogenetic tree and how the tree branches; compare and contrast homoplasy and heteroplasy in species; organize the bacteria, archaea, protists and plant kingdom life cycles and means of sexual and asexual reproduction; and distinguish and classify species characteristics of gymnosperms, angiosperms, fungi, and insects.
Version 1 and 2: Instruction is offered online through video lectures, study guides, required and supplemental readings, quizzes, homework, and final exams. Major topics include: evolution, proper scientific experiments, basic units of the body, Darwin’s natural selection, fossil rocks, extinction, speciation, Hardy-Weinberg Principle, genetic drift, gene flow, random mating, direction selection, disruptive selection, genetic resistance, mutations, non-random mating, sexual selection, morphological species, subspecies, allopatric speciation, vicariance, polyploidy, Hardy-Weinberg Law, phylogenetic tree, nodes, homoplasy, fossils, parietal bias, extinction, asteroid theory, bacteria, archaea, Miller experiments, Koch’s Postulate, extremophiles, nitrogen cycle, protists, potato famine, malaria, red tide, multicellularity, apoptosis, cilia, flagella, plants, plant-based fuel, plant uses, seed plants, phylogenetic tree of green plants, plant structure, plant adaptation, plant reproduction, plant life cycles, moss, heterosporous plants, seed dispersal, gymnosperms, angiosperms, fungi, mutualism, parasitism, commensalism, carbon cycle, s. cerevisiae, spore dispersal, insect history, insect diversity, insect morphology, metamorphosis, chelicerata, importance of insects, and insect reproduction.
