Quizlet Study Guide - Chapter 18 Taxonomy

Study your Chapter 18 notes as well as the practice (Smart Board Games, etc.) that we worked on in class.

Be able to...
  • Explain why taxonomy is needed in Biology.
  • Explain the need of a universal name and identify the two parts of the name.
  • List, in order, the 7 taxa from largest (most inclusive) to smallest (least inclusive, most specific).
  • List the 7 tax specific to the human species.
  • Given the taxonomy of different known and unknown species, be able to determine evolutionary relationships and physical similarities.
  • Identify the 3 accepted domains as well as the kingdoms that are included in each.
  • explain how and why the current 6-kindgom system was created from the previous 5-kingdom system.
  • Identify, compare, and contrast the 6 different kingdoms, especially with regards to their energy use, cell structure, and cell wall.
  • Given a list of traits, be able to identify the kingdom a known or unknown species belongs to.
  • Identify the traits of the Virus kingdom (Virea domain) and explain why they are currently not recognized as a living kingdom.
  • Define and/or use the following:
    • Taxonomy
    • Binomial nomenclature
    • Taxon (taxa)
    • Domain
    • Kingdom
    • Phylum (phyla)

Quizlet Study Guide - Chapters 16-1, 16-2, & 16-3 Genes & Evolution

Study your Chapter 16-1, 16-2, & 16-3 notes as well as the practice that we worked on in class.

Be able to...
  • Explain  how evolution can be observed genetically, specifically in relation to the relative frequency of certain genes/alleles in a gene pool.
  • Explain the concept of a gene pool and the relative frequency of genes/alleles in that gene pool.
  • Distinguish between the characteristics of single-gene traits and polygenic traits, being able to graph both using data from a gene pool.
  • Differentiate between directional, disruptive, and stabilizing selection graphically as well as descriptively. Also be able to propose plausible scenarios that could cause the changes in each type of selection.
  • Explain why genetic drift and the founder effect are considered random evolutionary changes.
  • Explain how genetic drift causes changes in the relative frequency of genes/alleles in a gene pool.
  • Explain how the founder effect causes changes in the relative frequency of genes/alleles in a gene pool.
  • Explain the implications of the Hardy-Weinberg Principle and its 5 criteria.
  • Identify the characteristics or abilities two individuals of the same species share. Likewise, identify the characteristics or abilities two individuals of the different species do not share.
  • Explain the necessary steps needed for a species to evolve into two different species via speciation.
  • Explain the importance of reproductive isolation in speciation.
  • Explain how changes can occur in separated gene pools in the process of speciation.
  • Define and/or use the following:
    • Gene pool
    • Relative frequency
    • Population
    • Natural selection
    • Single-gene trait
    • Polygenic trait
    • Directional selection
    • Stabilizing selection
    • Disruptive selection
    • Genetic drift
    • Founder effect
    • The Hardy-Weinberg Principle
    • Speciation
    • Reproductive isolation

Quizlet Study Guide - Chapters 15-1, 15-2, & 15-3 Darwin & Natural Selection

Study your Chapter 15-1, 15-2, & 15-3 notes as well as the practice that we worked on in class.

Be able to...
  • Explain how natural selection causes evolution to occur. In other words, explain why certain traits/adaptations become more common and why others become less common.
  • Explain what it means for an individual to be "fit" for its environment.
  • Compare and contrast Darwin's theory with Lamarck's. What are the three feature of Lamarck's theory of evolution and why is his theory be flawed?
  • Identify if a reasoning is Darwinian or Lamarkian in its explanation of evolutionary change.
  • Compare and contrast artificial selection and natural selection.
  • Provide examples of artificial selection.
  • Explain the concept of common descent.
  • Identify the six pieces of evidence that we have used to strengthen Darwin's theory.
  • Explain how fossil evidence strengthens Darwin's theory.
  • Explain what a homologous structure is and what it proves.
  • Explain what a vestigial organ/structure is and what it proves.
  • Explain how embryonic similarities strengthen Darwin's theory.
  • Explain how molecular similarities have been used to strengthen Darwin's theory. Which molecules are commonly used to prove relatedness?
  • Define the following:
    • Natural selection
    • Artificial Selection
    • Fitness (evolutionary)
    • Adaptation
    • Common descent
    • Homologous structures
    • Vestigial organs/structures

Adaptation & Evolutionary Change Project - Sample Partial ORQ Response

"The species dragon has changed due to natural selection and has adapted to an arctic environment.

It its original habitat, the dragon was a covered in scales with relatively little fur. Having adapted to an arctic environment, the dragon is now completely covered with a thick fur. The thick fur allows the dragons to maintain a healthy body temperature in an extremely cold environment. As the dragon migrated into the arctic, the extreme cold became a selection factor. Dragons that had more fur than others were more likely to maintain a proper body temperature and survive as well as reproduce. The dragons with less fur were more likely to die from the cold and less likely to reproduce. Over time, dragons with more fur became more common."

Notice how:

  1. The clarifying statement was used (see ORQ format)
  2. The new trait/adaptation is identified
  3. It is explained how the new trait/adaptation helps the species survive in its new environment
  4. It is explained how the original trait evolved into the new trait using logical and possible reasoning
Similar explanations must be used for 2 traits/adaptations for CP1 students and 4 traits/adaptations for CP2 students. All traits/adaptations must be included visually in the model.

*For this example, a mythological species was used. Students are expected to use non-fictional species.
