Biology

Each week will include multiple topics. Each topic will have reading, lectures to to listen to and take notes on, and a spot to turn in your lecture notes. The week will wind up with CPR (online research essay) & an exam on the week’s topics. Make sure to listen to the archived lecture for your notes that you submit. The powerpoints are NOT a substitution for, but rather meant to augment lecture retention.

Biology Case Study

  1.  LEGAL :  could any of these groups  SUE?

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.
