Assaignment # 1

The Discussion Board (DB) is part of the core of online learning. Classroom discussion in an online environment requires the active participation of students and the instructor to create robust interaction and dialogue. Every student is expected to create an original response to the open-ended DB question as well as engage in dialogue by responding to posts created by others throughout the week. At the end of each unit, DB participation will be assessed based on both level of engagement and the quality of the contribution to the discussion.

At a minimum, each student will be expected to post an original and thoughtful response to the DB question and contribute to the weekly dialogue by responding to at least two other posts from students. The first contribution must be posted before midnight (Central Time) on Wednesday of each week. Two additional responses are required after Wednesday of each week. Students are highly encouraged to engage on the Discussion Board early and often, as that is the primary way the university tracks class attendance and participation.

The purpose of the Discussion Board is to allow students to learn through sharing ideas and experiences as they relate to course content and the DB question. Because it is not possible to engage in two-way dialogue after a conversation has ended, no posts to the DB will be accepted after the end of each unit.

Background

Biotechnology allows the use of living organisms or their processes for human needs or purposes. Currently, this topic includes such general examples as cloning, stem cells (adult, umbilical cord, and embryonic), DNA fingerprinting, biological warfare, bioremediation, genetically modified organisms, vaccines, and transgenic plants and animals to name a few. In this assignment, you will explore specific examples of biotechnology applications.

Assignment Details

Part 1

Biotechnology is the use of a living thing or any part of a living thing to make a product or process that improves human life. For this part of the assignment, discuss the following:

What are some of the examples of biotechnology that have made improvements to your life?
Describe how one of these has made your life better.
Do you have any concerns with biotechnology? Explain.

Part 2

In 2008, the Food and Drug Administration (FDA) approved food derived from cloned animals. In addition, these products will not need to be labeled as “cloned” or “from clones” (Black, 2008). The FDA explains that you will not be eating the clone itself. It takes thousands of dollars to clone a food animal such as a cow or pig. Animals that are cloned for improved food production will be used for a breeding program to produce many offspring with the desirable traits for increased meat or milk yield. These offspring of the clones will be fair game for food. Discuss the following:

Do you think there are differences between a clone and a "normal" animal?
How do you feel about eating a cloned animal?
Is your opinion of eating a cloned plant different?

In your own words, please post responses to the Discussion Board posts of at least two of your classmates. Responses must be substantive, i.e. say something of substance that advances the discussion about the concepts. You will be graded on the quality of your postings.

Assaignment # 2:

Background

For many years, antibiotics have been effectively used to treat bacterial disease; and pesticides have been used to protect our agricultural crops from many kinds of pests, including insects, worms (nematodes), fungi, or agricultural weeds, for example.

A growing concern for treating bacterial diseases or pest outbreaks is the evolution of antibiotic or pesticide resistance by bacterial or pest populations. Resistance means that a particular antibiotic is no longer effective in treating a disease, or that a particular pesticide will no longer prevent crop damage. This resistance can be viewed as evolution of a new trait at the population level, which is resistance to an antibiotic or to a pesticide. In this assignment, you will explore specific examples of antibiotic or pesticide resistance.

Assignment Details

Methicillin resistant Staphylococcus aureus (MRSA) has become a big concern in hospitals throughout the country and the world, as have other antibiotic resistant bacterial strains.

Part 1

The use, overuse, and abuse of antibiotics is accredited with creating these antibiotic resistant strains. Explain how this relates to natural selection.
Describe 1–2 of the things that people do (you can include individuals, doctors, health care professionals, hospitals, farmers, etc.) that contribute to this problem? Why?

Part 2

How can you prevent or slow down the spread and further the selection of new antibiotic resistant strains of bacteria?
Are there things that you can personally do to reduce your risk or even to reduce the spread of these dangerous microbes?
What is your reaction to the following sign that is commonly found in restrooms? Is it significant to the discussion of antibiotic resistance?

Assaignment # 3:

Background

Angiosperms (flowering plants) are the largest Phylum in the plant kingdom Plantae. (Note that the Phylum Angiospermophyta may also be called Anthophyta or Magnoliophyta in different classification systems.)

These plants have true roots, stems, leaves, and flowers. The roots grow into the soil to anchor the plant in place and take up water and nutrients. The leaves are above ground and act as the main organs for photosynthesis. Stems provide above ground support for the plant and operate as conduits to move nutrients and water throughout the plant. Flowers contain the male and female reproductive organs of the plant.

Assignment Details

Part 1

Plants develop specialized roots, stems, leaves, and flowers to make them better adapted to their environment. People exploit many of these modifications as vegetables. An example of this is the taproot of carrots. The carrot plant stores sugars in the taproot to supply energy for the formation of flowers in later development. People dig up and eat the taproots while the sugar content is still high. Complete the following:

Describe the anatomy (structure) and physiology (function) of a plant. Is the structure of your plant a modification from the standard root, stem, leaf, or flower?
Explain how this structure differs from the standard root, stem, leaf, or flower.
Compare the plant that you have chosen, its structure, and its function with 1 or more of your classmates’ choices.

Part 2

Animals are important for humans in ways other than providing food. Medicines, clothing, beauty, fuel, air quality, building materials, and industrial products are a few of the ways in which humans exploit animals. Complete the following:

Choose 1 product or benefit that people get from animals (besides food), describe it, and explain how people benefit.
Which do you think is the most important benefit of animals? Select 1 benefit and explain.
List 3 adaptations that animals have that plants do not have.

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. Be sure to compare and contrast your choice to other plants presented by at least two other students by responding to their posts, using "Reply to Message." You will be graded on the quality of your postings.
