  • Tutorials on several important biology topics have been created for student use. Each tutorial contains a description of the biology topic, an animation and quiz to test your knowledge. Please contact Dr. Alexander Edens at aedens@hartnell.edu  for more information.

    • Cellular Respiration
      The goal of this tutorial is to learn about cellular respiration, including Glycolysis, Krebs Cycle and the Electron Transport Chain.
    • Cell Cycle and Mitosis
      The goal of this tutorial is for you to learn the phases of of the cell cycle and mitosis and the important events that take place during each phase.  Complete all three portions of this tutorial:
    • Cell Structure and Function
      The goal of this tutorial is for you to be able to describe cell theory, differences between prokaryotic and eukaryotic cells and understand cell structure and function.
    • Development
      The goal of this tutorial is to learn about the basics of early development from fertilization through gastrulation and major differences in early development between taxonomic groups.
    • Diffusion and Osmosis
      The goal of this tutorial is for you to be able to describe the movement of molecules in the processes of diffusion and osmosis.
    • DNA Replication
      The goal of this tutorial is for you to learn the process of DNA replication and the major players involved.
    • Eukaryotic Life Cycles
      The goal of this tutorial is for you to gain knowledge about the 3 major eukaryotic life cycles: gametic, zygotic and sporic.
    • Genetics
      The goal of this tutorial is for you to be able to identify important terms used in genetics, how to use a Punnett square to determine the outcome of a cross with 1 trait or 2 traits, and how to use the product rule to determine the outcome of a cross with any number of traits.
    • Meiosis
      The goal of this tutorial is for you to learn the stages of Meiosis and describe the important events that occur at each stage. Upon completion of this tutorial, you will also be able to compare and contrast mitosis and meiosis.
    • Microevolution
      The goal of this tutorial is to learn about the difference between macroevolution & microevolution, how Hardy-Weinberg equilibrium works as well as factors that can upset this equilibrium and how to use the equation, \(p^2 + 2pq + q^2\) = 1, to calculate allele frequencies in a population.
    • mRNA Splicing
      The goal of this tutorial is for you to learn the process of splicing and the major players involved in the splicing process.
    • Natural Selection
      The goal of this tutorial is for you to learn how natural selection provides a mechanism for evolution, natural selection results from selective pressures in the environment and is not random, there are also random processes like genetic drift that can upset genetic equilibrium and only natural selection results in adaptation.
    • Photosynthesis
      The goal of this tutorial is for you to gain knowledge of the light dependent and light independent (Calvin Cycle) reactions of photosynthesis.
    • Scientific Literature
      The goal of this tutorial is to learn about what peer-reviewed scientific literature is, the components of a peer-reviewed research paper and how to cite a research paper.
    • Scientific Method
      The goal of this tutorial is for you to learn about the scientific method and be able to apply that knowledge to problems.
    • Signal Transduction
      The goal of this tutorial is for you to gain an understanding of how cell signaling occurs in a cell. Upon completion of the tutorial, you will have a basic understanding signal transduction and the role of phosphorylation in signal transduction. You will also have detailed knowledge of the role of Tyrosine kinases and G protein-coupled receptors in cell signaling.
    • Taxonomy & Phylogeny
      The goal of this tutorial is to learn about the traditional classification scheme of Linnaeus; two theories of taxonomy: traditional evolutionary taxonomy and Cladistics; how to read a cladogram.
    • Tissues
      The goal of this tutorial is for you to be able to identify the four tissue types in the human body, describe their function and unique characteristics.
    • Transcription
      The goal of this tutorial is for you to learn the process of transcription, including the major players involved and the basics of RNA processing.
    • Translation
      The goal of this tutorial is for you to learn the process of translation.
