ASSIGNMENT 1
SCIE 206 UNIT 2 DISCUSSION BOARD
Deliverable Length:4-5 paragraphs
Details:
Background:
When you look at the world around us, you can see many examples that demonstrate how an object's or
a system's structure relates to its function. The structure of a highway system, for example, can affect
traffic flow. You can, no doubt, think of many other examples.
In this discussion board, you will look at the structure of the most basic unit of life, the living cell. And, you
will investigate how the structures of cells are directly related to functions that are important to life.
Assignment details:
Please answer the following three essay questions.
All living cells, both prokaryotic and eukaryotic, have the following cell structures: plasma membrane,
cytosol, ribosomes, and at least one chromosome. Choose any one of these. Describe its basic structure
(including molecular composition) as well as the function. Explain why a cell could not exist without the
function(s) performed by this cell structure.
Cells can be categorized as either prokaryotic or eukaryotic. Only bacterial cells are prokaryotic. For
question two, answer any one of the following comparison questions. Be sure to compare both molecular
(physical) structure and function in each answer.
Compare the nucleoid area (prokaryotic) to a nucleus (eukaryotic)? How do they differ; how are they
similar?
Compare the bacterial flagellum (prokaryotic) to an animal cell flagellum (eukaryotic)? How do they differ;
how are they similar?
Compare a bacterial cell wall (prokaryotic) to a plant cell wall (eukaryotic)? How do they differ; how are
they similar?
Eukaryotic cells (in plants, animals, fungi, and algae) are bigger than prokaryotic (bacterial) cells. This
bigger size allows eukaryotic cells to have more structural complexity.
Choose any one of the following eukaryotic cell structures for a short essay:
Mitochondrion
Cytoskeleton
Golgi apparatus
Endoplasmic reticulum
Lysosome
Chloroplast (found only in photosynthetic cells)
In your answer, describe its basic structure (including molecular composition) as well as the function. Why
is the function important to keeping the cell alive?
Provide references in APA format. This includes a reference list and in-text citations for references used
throughout the assignment.
In your own words, please post a response to the Discussion Board and comment on other postings. You
will be graded on the quality of your postings.
ASSIGNMENT 2
SCIE 206 UNIT 2 INDIVIDUAL PROJECT
Deliverable Length:2-3 pages
Details:
Background:
Whether it was volcanic activity that spewed sulfur dioxide and ash into the atmosphere, or a giant meteor
that crashed into the Earth blasting dust and debris into the sky, both theories of what caused the
dinosaurs to become extinct share one critical similarity -- light from the sun was obliterated. The result of
the months' long darkness was the mass extinction of nearly 70% of all creatures on Earth.
Like the dinosaurs, humans cannot live without the sun. Not only does it provide light and warmth, it is
also the energy source for arguably the most important chemical reaction on Earth: photosynthesis.
Answer the following assignment questions:
1. Explain how photosynthesis and respiration are linked in order to provide you with energy from the food
you eat.
Include in your essay:
Complete descriptions of photosynthesis and aerobic respiration.
Describe how these two processes are linked between plants and animals based on the reactants and
products (water, carbon dioxide, glucose and oxygen) of both pathways.
Include a description of how energy is transferred from sunlight to ATP, from ATP to sugars, and from
sugars to your cells.
2. In the absence of oxygen some cells and organisms can use glycolysis coupled to fermentation to
produce energy from the sugar created by photosynthesis.
Explain the role of fermentation in allowing an organism to generate energy for its cell(s) in the absence
of oxygen.
Include any reactions required for this process, and explain how the energy from the sun ends up as
chemical energy for the anaerobic organism or cell.
3. Cells use enzymes as biological catalysts to increase or accelerate the rate of reactions, such as those
in photosynthesis or glycolysis. This allows reactions to occur under conditions that sustain life.
Explain how an enzyme catalyzes a reaction. Include in your essay the three main steps of the cycle of
enzyme-substrate interactions.
How is enzyme activity regulated by the cell?
ASSIGNMENT 3
SSCI 210
Deliverable Length: 2–3 pages
Details:
Select a movie or TV show that effectively communicates the cultural, values and norms of a society that
is different from your own culture. Ideally, this movie or TV show would be a foreign film with subtitles.
The movie or TV show you select should provide you with a glimpse of what life is like in another culture.
The process of watching this movie or TV show should provide you with a unique, cultural experience.
Watch the movie/TV show that you selected, and use your reactions as part of your response to the
following topic: Define ethnocentrism and how it affects individuals, societies, and multinational
corporations.
Your paper should provide a comprehensive overview of the concept of ethnocentrism. You should use
your cultural experience of watching the selected movie or TV show to discuss the effect of ethnocentrism
on individuals, societies, and multinational corporations. Please feel free to use any personal experiences
you may have had visiting different countries around the world as part of this paper; however, do not let
your personal experiences with other cultures be the focal point of this paper. The focal point of the paper
is your cultural experience watching the selected movie or TV show and your comprehensive overview of
the concept of ethnocentrism. Please note that this paper is not intended to be a summary of the movie or
TV show. Your paper should focus on the cultural observations that you are able to make based on this
experience. Your response should be 2–3 pages.
ASSIGNMENT 4
Healthcare Class
5 page essay
details:
People being treated for mental health issues represent only a small percentage of the patients who need
attention and services.
Topic:
What factors obstruct the access to mental health treatment for those needing treatment?
ASSIGNMENT 5
You are encouraged to research a topic of your choosing related to the course content. This
may include a topic in which you are interested and want to learn more, a problem you would
like to solve, or an answer or response to a situation. If you do not want to select your own topic
you may select from the example topics below. Either way, instructor approval is required by the
end of Module 2.
Topic:
Stress Management in a Specific Position of Employment. (YOU CAN CHOOSE THE JOB
POSITION)
APA format must be used for the paper. Research papers will be 6-10 pages in length. Note that 6-10
pages means 6-10 pages of double-spaced typed material with one-inch margins left, right, top and
bottom, and Times New Roman, 12-point font. The cover sheet, table of contents, index, pictures, long
quotations or multiple quotations will not count toward the 6-10 pages. Students must cite all sources
and use a minimum of five in their research papers. Wikipedia cannot be used as a source.
