which ones?

WHAT SHOULD the argument be if they sue?

Who would  win? WHY?

What should the settlement be (not just money)?

What group should have stepped in and stopped this? and HOW?

  1. ETHICAL: Were the doctors who gave this to women responsible for what happened to them and subsequent generations?  WHY or WHY NOT?
  2. Why did these women take an unknown substance?
  3. This has happened very few times in medical history.  Find one example that has happened recently and tell me about it
  4. A new area of genetics called EPIGENETICS (page 134) has recently given an explanation about what might have happened.  What isepigeneticsand how does it fit into the case?

 

  1.  future of DES.  Do you think this could go on for many generations in the future.  EXPLAIN.

 

8 find a family  that has been affected by DES and write their story.

 

  1. the worst thing about this is it will follow generations and we aren’t sure how it will affect them. Look at the chart and make a prediction what you think happen in the future.

 

There is a chart, reading and information about all generations on page 141 but the questions above need research to answer, and I am attaching it here.

Unit III Homework Blood Typing

Introduction

Blood typing is critical in medicine. If a person receives the wrong type of blood, they can die. The purpose of this virtual lab is to allow you to simulate determining the blood type of three patient. You will then have to decide what type of blood to give your patients. Good luck; hopefully, you will save lives.

 

Objectives

 

  1. Determine blood types that blood groups can receive.

 

Materials

 

Computer with internet access

 

Directions

 

Go to Nobelprize.org: The Blood Typing Game at http://nobelprize.org/educational_games/medicine/landsteiner/

 

  1. Click on: PLAY > PROCEED > QUICK GAME – SAME PATIENTS
  2. Click on MAIN MENU, and read the three tutorials.
  3. Click on START PLAYING. Follow the instructions in the lab to answer the following questions. Select the patients in order from left to right. You will have to drag the needle to the patient’s arm and then put the blood in the tubes to determine the blood type.
  4. Type all answers directly on the data sheet.
  5. Select Save As, and use your last name and student ID as a file name.
  6. Upload the data sheet as a .doc, .docx, or .rtf file when finished.

 

Questions: Questions 1-10 are short answer questions and should be answered in complete sentences. Total: 100 points

biology

Gene technology carries with it social and ethical implications—many of which engender personal views and discussion.

Select one (1) of the following biotechnology topics to write about:

  • Genetically modified crop plants
  • Genetically modified microorganisms
  • Genetically modified animals
  • Personal genomics and / or personalized medicine for humans
  • Gene therapy

Write a four to six (4 to 6) page paper on your chosen topic.  Organize your paper into sections corresponding to the following requirements:

  1. Biological basis. Describe the technology. Discuss what it accomplishes. Elaborate on the scientific principles that make this technology possible. Your goal in this section of the paper is to show the instructor that you understand the underlying science behind the technology. Describe how exactly the technology works. Discuss the biological principles that underlie this technology.
  2. Social and ethical implications. Without disclosing your personal view about this technology, provide an analysis of its social and ethical implications. State the ethical concerns apparent in the use of this technology. Discuss the benefits and risks. Your goal in this section is to look at all sides of the issue. In the next section, you will give your opinion.
  3. Personal viewpoint. In the previous section, your goal was to be as objective as possible, to look at all sides of the issues. In this section, your goals are to give a personal opinion about the technology and provide a justification of that opinion.
  4. Use at least three (3) quality resources in this assignment, in addition to the course text. Note: Wikipedia and similar Websites do not qualify as quality resources. The body of the paper must have in-text citations that correspond to the references. Integrate all sources into your paper using proper techniques of quoting, paraphrasing and summarizing, along with proper use of in-text citations to credit your sources.

Your assignment must follow these formatting requirements:

  • Be typed, double spaced, using Times New Roman font (size 12), with one-inch margins on all sides; citations and references must follow APA or school-specific format. Check with your professor for any additional instructions.
  • Include a cover page containing the title of the assignment, the student’s name, the professor’s name, the course title, and the date. The cover page and the reference page are not included in the required assignment page length.

The specific course learning outcomes associated with this assignment are:

  • Examine DNA structure, and function, gene expression, and control.
  • Discuss the various applications of genomics and biotechnology.
  • Use technology and information resources to research issues in biology.
  • Write clearly and concisely about biology using proper writing mechanics

Biology – Evolution

explaining why certain characteristics guided you to select one ancestor over another for a specific genus. Many different genera have common ancestors but often due to evolution, there is branching within the family tree so that members of the same genus will have a common ancestor not shared by other genera.
