lab 8


  • Biodiversity
  • Goal: better understand the differences in different types of living organisms
  • Bacteria: single cell, no nuclei, mostly heterotrophic, some decomposers, parasites, mutualists, some autotrophs, chemoautotrophs
  • Bacilli shape, coxus shape, spirilli shape
  • Protists: large size, single or multicellular, membrane bound organelles, complex DNA and nucleus
  • Mix of parasites, autotrophs, heterotrophs, primarily aquatic
  • Plants: lower plants are primitive and simplistic and upper plants
  • Lower: things like moss
  • Higher: plants like bushes and flowers and such
  • most are photosynthetic
  • Materials: microscopes, prepared slides

Lab 7

  • Sickle cell anemia: identifying sickle cells which can cause blood clots and lack of oxygen to the body parts resulting in organ failure
  • Gel electrophoresis to seperate hemoglobin proteins, sickle cell is negative charged and will go positive side
  • Materials: electrophoresis machine, pipet, gel plate, salty solution.
  • Transcription and translation- meant to show us how genes work
  • Two step process: transcription in the nucleus and Translation in the cytoplasm
  • Genetic architecture: get a better sense of how alleles fit together, and determine what the parental phenotypes were through looking at the offspring
  • Materials: Punnet squares, Rebop, random alleles in an envelope.

  • Looking for color change in different foods
  • Measuring vital signs at rest
  • Measure resting heart rate
  • Measure blood pressure systolic and diastolic
  • Materials monitoring systems

Lab 5

Lab October 2nd
Mitosis and cytokinesis same thing
Most of the cells life is spent in interphase
Five stages of mitosis

  • Prophase-  appearance of chromosomes
  • Metaphase- chromosomes line up along equator of cell
  • Anaphase- splitting of chromatids
  • Telophase- segregation of chromosomes
  • Cytokinesis- two new cells

    Mateirials: HCl, tip of root, dye, H2O,
