Properties of the skin and their relation to fingerprints.

/in /by

Explain the properties of the skin and their relation to fingerprints.

Fingerprint
Part 1
Open and analyze the Part 1 picture as if you were a latent print examiner. You will see an impression with ridge events and features marked. You should:

  • Identify the pattern.
  • Determine what the indicated ridge events/features are, including the pattern type (there are a total of 20 items to classify). Simply make a list on 1 page and list from (1–20) and write down your labels, i.e., type of pattern, bifurcation, creases, dot, ending ridge, pore etc. DO NOT provide an explanation of these items.

Part 2
Explain in a 1 page essay the properties of skin and the relationship to friction-skin impressions. Consider such items as elasticity, scarring, distortion, the condition of the skin etc.
Note: Part 2 is an Essay that is independent of Part 1.

Part 3

  1. Obtain a small ink pad (any color).
  2. Roll your fingerprints on the pad from nail edge to nail edge until the finger is covered with ink.
  3. Roll your finger from nail edge to nail edge onto a white index card or piece of white paper. Be careful to make this one smooth movement without double rolling.
    Examine your own fingerprint, keeping in mind the types of fingerprints discussed in your reading. Describe both your experience and your results.

The Drosophila dihybrid cross

/in /by

Write a short lab report using the data below. The lab report is based on the Drosophila dihybrid cross in Exercise 5.

Write a few paragraphs in the following format:

  1. Abstract: Summarize your paper in one paragraph.
  2. Introduction –write any background information including the description of the experiment, and stocks used. State your hypothesis here.
  3. Results: Let’s assume in the F2 generation, the following results were obtained:
    Drosophila Dihybrid Cross-F2 Results

Wildtype- 1750
Vesitigial- 535
Ebony-500
Ebony and Vestigial- 150

A) Write down all crosses set up to obtain this results (use the lab manual). Deal with one cross at a time: P l, Fl, F2. Set up a Chi square table with the results above.
B) Calculate Chi-square and p-value for the results. State whether you will accept or reject your hypothesis.

  1. Discussion -discuss your results in context of what is known about autosomal inheritance patterns in Drosophila and you understanding of your hypothesis

Children’s book analysis

/in /by

A. Identify one illustrated children’s book that must meet the following criteria:

• have a positive diverse representation

• be appropriate for an elementary or middle-grade level (grades K–8) classroom

• be fiction, unless it has narrative elements, such as biography, memoir, or narrative verse

• not contain religious instruction

B. Using the book chosen in part A, do the following:

Note: An example could include a quote, paraphrase, copy of an illustration or a description of an illustration from the book. Examples must be cited.

  1. Describe the positive diverse representation in your children’s book.

a. Explain how the diverse representation in your children’s book helps students gain perspective for understanding the world. Support your explanation with a specific example from your chosen book.

  1. Identify a literary theme of the selected book (e.g., kindness, courage, cooperation, etc.).

a. Explain how one specific example of a literary element used in the book (e.g., plot, setting, characterization, figurative language, etc.) supports or conveys the theme from part B2.

  1. Explain why it is important to select children’s literature with quality artwork, illustrations, or images. Support your explanation with evidence-based research or resources from your course.

a. Include a copy of an illustration from your chosen book, and describe how the illustration in the chosen book conveys the theme.

  1. Identify the specific genre of your chosen book.

The story; The Raven.

/in /by

Write a critical response to the story The Raven. The critical response should examine the story not only in terms of what themes and elements are contained within, but also how those elements are relevant in a modern day. For example, if you determine that a story deals heavily with obsession, you might then ask what are things that people obsess over in the modern day? Even though this will be based on your own conclusions, this should NOT be written from first person; all responses should be third person objective. Critical responses should use quotes and paraphrases from the original work in order to prove their assertions about the story. What you are really doing is analyzing what about the story might make it relevant even in the modern day.
