Biology Assignment 4

Deliverable Length: 2 files

Many of the most devastating human diseases result from an attack of
various microbes (viruses, bacteria, fungi) on the human body. The flu
epidemic of 1918 killed 22 million Americans and Europeans in just 18
months, and our ongoing war against the HIV virus is still waging. In
order to fight against this onslaught, the human body developed a
sophisticated system that is able to screen, identify, and destroy
invading microorganisms before they cause severe damage to the human
body. This system, called the Immune System, continuously monitors our
blood stream for the presence of foreign cells or molecules. Once an
infection is recorded, the system is able to launch a full-scale attack
directed against the specific invader. Organisms with compromised immune
systems, or those lacking immune systems, cannot survive for long.
Infections that are able to escape or destroy the immune system’s
surveillance (such as HIV) are extremely dangerous.

 You work for a company which creates posters and informational
material for doctor's offices. Your new project is to prepare
information on the immune system. This information will be sent to
graphic designers later to polish the visuals, but you need to ensure
that the content is accurate:

 1. The immune system is composed of several types of cells whose
coordinated, concerted effort is required for screening, identification,
and eventual purging of microbial invasion. Create a network diagram
showing the components of the immune systems and the interaction and
relationships between them.

 2. Sometimes too much of a good thing is not so good. When our immune
system detects a foreign molecule and mounts an immune response, it is
sometimes unaware that the foreign molecule is actually completely
harmless. Many cases of allergies are a result of an aggressive immune
response against an organism or molecule that harbors no real threat to
our body. What are the components of our immune system involved in
allergic reactions, and how does treatment of allergies manage to
control them? Create a one-page brochure designed to explain the causes
of allergies and tips for allergy management to a non-scientific
audience.

 You may use either Word or PowerPoint to create your network diagram;
create the brochure as a Word document. Your final product should be in
two files: one with the network diagram, and one with the brochure. Use
the Internet, and other resources to research these topics. Be sure to
cite all sources in APA format.

 Further Instructions:

 Question 1: Network Diagram for the Immune System:  you can use
either PowerPoint or Word.  The emphasis is on the quality and accuracy
of your diagram.  Visual presentation helps to clearly show the
components of the Immune System, but fancy graphic design is not
important.

Question 2: Brochure describing the allergic reaction and tips for
managing allergies.

This is limited to ONE page... and should be created in Word. The
reference list can be placed on a separate page.  Again, the emphasis
is on accuracy and content rather than visual design.  While the text
is useful as a reference, please be sure to use at least one additional
authoritative reference for this question from the Internet or another
credible resource. 

Please submit these as two separate files for review.

Grading Criteria:

Clearly describing the interactions in the immune system, the causes of
allergies, and tips for controlling allergic reactions as described
above. 

Using the Internet and authoritative resources to support your
conclusions

Correct spelling and grammar

Summarizing in your own words, paraphrasing, and using quotes for
information taken from references.

Listing and citing all references used in APA format.

 

Biology Discussion 4

Deliverable Length: 3-4 paragraphs

Argue for or against the statement, "Viruses are alive." The internal
structure of many protists is much more complex than that of cells of
multicelluar organisms. Does this mean that the protist is engaged in
more complex activities than the multicellular organism? If not, why
should the protistan cell be much more complicated?

 Further Instructions:

Are viruses alive? This is an interesting question and you should be
able to find this debated in references. You will want to read about
viruses. Once you understand the characteristics of viruses and how they
function, review the characteristics of living cells to help you select
your position.

 

Organisms in the Kingdom Protista exist mostly as unicellular organisms,
although they can sometimes group together in colonies. There are many
types of Protists with many different functions depending on their
environment. Their cells are Eukaryotic. Think about what it means to
be a cell that functions as a unicellular organism vs. what it means to
be a cell in a multicellular organism to help you answer these questions
about Protists. 

  

For this Discussion, you will be graded on:

Taking clear positions about the questions in this DB and supporting
your positions by using data from reference(s) such as your text or
other authoritative sources.

Correct spelling and grammar

Summarizing in your own words, paraphrasing, and using quotes for
information taken from references.

Listing and citing all references used in APA format.
