SCI206 BIOLOGY UNIT 5 IND ASSIGNMENT SOLUTION

Part 1Animals are placed in taxonomic classifications based on differences and similarities of their traits. If you know what critical traits to look for, it is possible to separate any animal into a taxonomic category.
Download the document U5IP Table.
The document contains a table with images. The images are examples of each Phylum: Porifera, Cnidaria, Platyhelminthes, Annelida, Mollusca, Arthropoda, Nematoda, Echinodermata, and Chordata.
First, use the table in your textbook (page 428) to determine which Phylum each organism falls into (you will find a description of chordata on page 450). List the specific traits that distinguish each Phylum . (Please do not just copy the list from the table. Read through the text to pull out detailed characteristics.)
Next, download the document, U5IP_Dichotomous_key.htm , and use the Dichotomous Key to help determine the taxonomic category in which each specific organism belongs. For help on how to use the Dichotomous Key, download the document, U5IP_How_To_Dichotomous_Key
Attachment(s):Dichotomous key[1].pptU5ips_v2.doc
Part 2
Examples of nine Animal Phylum: Porifera, Cnidaria, Nematoda, Arthropoda, Platyhelminthes, Annelida, Mollusca, Echinodermata, and Chordata.
jellyfish, snail, earthworm, fly, spong, starfish, snake, flatworm, roundworm
1.Which group(s) lack tissue level organization?
2.Which group(s) of organism(s) begins to show cephalization?
3.Do all organisms on the chart have 3 germ layers (endoderm, ectoderm and mesoderm)? If not which groups lack all three?
4.One group has more species than all the other groups, give the name of the Phylum and examples of species found in this group.
5.Do all fish have the same skeletal structures? If not, describe the differences.
6.Describe the 3 different types of mammals.

MICROBIOLOGY QUESTIONS

Please read assignment carefully and feel free to ask if you have questions!

Document Preview:

Your answer for each question should be a minimum of 150 words (half page). Please number your answers and print the number of the question you are answering above your answers.
Identify subsections accordingly and cite sources in APA format.
1) Blood isolated from an emergency room patient contains antibodies against the measles virus. Please explain whether or not the patient should be quarantined immediately because they are infected with the measles virus and why? What are the other plausible explanations for anti-measles antibodies in the patient’s blood?
2) Describe how the clonal expansion theory explains the more rapid production of antigen
specific antibodies, Helper T-cells and Cytotoxic T-cells, during a secondary infection.
3) Positive diagnosis of AIDS is made when a patient has antibodies against the human
immunodeficiency virus (HIV). Please explain why the patient has an immune deficiency
if he or she is making antibodies?
4) Characterize the differences and similarities between innate and adaptive immunity in
form and function.
5) What is the effect of discharging primary treated sewage on the biochemical oxygen demand
(BOD) and dissolved O2 (DO) of the receiving body of water? What is the effect of secondary-
treated sewage on the BOD and DO?
6) A newspaper headline reported “Algal Bloom Kills Fish.” As you read, you find that the algae did not produce toxins. Please explain what actually caused fish death, given that the algae are
not toxic? What could have caused the algal bloom?
7) What is fermentation and how can it be used to preserve foods? Please give specific
examples in your explanation.

Describe the mechanisms of pathogenicity.

B. From the second e-Activity, determine how the very large U.S. national debt could affect interest rates over the next five years and the impact on market stability within the U.S.
e-Activities
Go to the MSNBC Website to read the news transcript titled “Fed says it will hold rates fast until mid-2013,” dated August 9, 2011, located at http://www.msnbc.msn.com/id/44064023/ns/business-stocks_and_economy/t/fed-says-it-will-hold-rates-fast-until-mid-/#.T1jUNHkmx8E. Be prepared to discuss.
Go to the USDebtClock.org Website to review the current U.S. national debt, located at http://USdebtclock.org. Be prepared to discuss.
3A. When the economic crises in the countries are due to a weak economy, local interest rate tends to be very low. However, if the crisis was caused by an unusual high rate of inflation, interest rates tend to be very high. Explain why?
3B. Global financial market regulations. Assume that countries A and B are of similar size, that they have both similar economies, and that the government debt level of both countries is within reasonable limits. Assume that the regulation in the country A require complete disclosure of financial reporting by issuers of debt in that country but that regulations in the country B do not require much disclosure of financial reporting. Explain why the government of country A is able to issue debt at a lower cost that the government of country B.
