There are 7 parts provided below. I will most definitely be tipping, I really appreciate it! Please just try to do your best.
4.02- For this assessment, you will read and analyze a case study on a patient with a blood disorder. There may be some medical terms or procedures in the case study that you do not know or understand. Please use reliable internet resources to do whatever research is necessary to define terms and get additional information on diseases and symptoms mentioned in the case study. However, make sure your answers are in your own words and are supported by specific evidence from the text. FILE PROVIDED
4.03- WERE THE BABIES SWITCHED?
Two couples had babies in the same hospital at the same time. Michael and Danielle had twins, a boy, Michael, Jr., and a girl, Michelle. Denise and Earnest had a girl, Tonja. Danielle was convinced that there had been a mix-up and she had the wrong girl, since Michael Jr. and Tonja were both light-skinned, while Michelle had darker skin. Danielle insisted on blood type tests for both families to check whether there had been a mix-up. In order to interpret the results of the blood type tests, you will need to understand the basic biology of blood types.
Were the babies switched?
GENETICS OF BLOOD TYPES
Your blood type was established before you were born, by genes inherited from your mother and father. This blood type gene has three different versions or alleles that code for different versions of a protein enzyme as follows:
-The IA allele codes for a version of the enzyme that puts Type A carbohydrate molecules on the red blood cells.
-The IB allele codes for a version of the enzyme that puts Type B carbohydrate molecules on the red blood cells.
-The i allele codes for an inactive version of the enzyme, so red blood cells have neither type of carbohydrate molecule on their surface.
Everyone has two copies of these genes, one allele from their mother and one allele from their father. There are six possible combinations of allele a person can have.
-IA IA = Blood Type A
-IA i = Blood Type A
-IB IB = Blood Type B
-IB i = Blood Type B
-IA IB = Blood Type AB
-i i = Blood Type O
WERE THE BABIES SWITCHED?
Now you are ready to evaluate whether Earnest and Denise’s baby girl was switched with Michael and Danielle’s baby girl. The following family trees show the blood types for each person in both families:
Using the blood types of the parents, make a table to identify the possible blood types for Michael Jr, Michelle and Tonja.
Baby – Possible Blood Types
——————————————————————-
-Michael Jr. –
-Michelle –
-Tonja –
——————————————————————
Is it possible for Michael and Danielle to have a child who has type O blood? How do you know this?
Was a switch made at the hospital? Explain your reasoning.
How could fraternal twins be as different in appearance as Michelle and Michael, Jr., including one having light skin and the other having dark skin?
5.02- Digestive system
Did you know it takes at least six hours for food to get to the end of your small intestine, and then it takes an average of 40 hours for food to make it through your large intestine? That means the food you eat today is still with you tomorrow, and the day after that.
In this assessment, you will journal the hourly life of a fatty acid or a sugar molecule as it makes its final voyage through the digestive tract. You only need to journal the first seven hours of the digestive passage. This means you should have a total of seven journal entries.
Your journal entries should be creative and include descriiptions of all the alimentary and accessory organs, including their secretions. You should also mention which type of digestion is happening in each organ and include the nervous or endocrine system controls that affect the digestion of your molecule. Remember, a fatty acid and a sugar molecule are digested and absorbed in a slightly different way. Be sure your journal covers the correct voyage for the molecule you choose.
5.03-Molecules
Your task is to create three cartoon superheroes using one type of carbohydrate, one type of lipid, and one protein. The end product should have three drawings, each with the structure of the molecule incorporated in some way. It should also include a descriiption of the character and a creative name. The descriiption should include the following information:
The character’s special powers (what the nutrient does for the body)
How the character gets the special powers (List at least three foods that provide the nutrient)
6.01-Excretory System
Create a flow chart to represent and describe the process of urine formation in the kidneys. You can use any flow chart format that you wish but you must include the components below:
ADH
Hypothalamus
Liver
Nephrons
Pituitary
Urea
Renal tubule
Glomerulus
6.02- immune system
Florence Flu and her brother Frank Flu are invading viruses with a mission to get you sick! It’s time to describe all the defenses they will encounter as they battle your immune system.
Complete the 5 missing sections of the story below with great detail. The missing portions of the story should be added using complete sentences. Before you begin writing, go back and review your lesson notes including the video worksheeets. Submit a copy of your completed story in the assessment area.
COMPLETE THE MISSING SECTIONS OF THE STORY BELOW WITH ENOUGH DETAIL TO FULLY TELL THE STORY.
Florence and Frank Flu are waiting patiently on a door knob for their chance at a pickup. As your hand approaches the door knob, they seize the opportunity and latch on to your skin. What will happen to Florence and Frank as they attempt to find an entrance to your body?
1.
As you enter your kitchen, you snag an orange from the fruit bowl and begin to peel away the skin. When you pop an orange slice in your mouth, Florence Flu slides in too. What chemical barriers will stop her now?
2.
Florence is dead, but Frank Flu has found a way into your body through a tiny cut on your hand. Which non-specific chemical and biological immune responses could destroy Frank Flu before he replicates? Describe exactly how each of these responses could take Frank down!
3.
Your non-specific immunity killed Frank, but not before he managed to infect a cell and replicate. His clones are everywhere and now your specific immunity must take over. List and describe all the components of your specific immunity that will destroy all the Frank Flu clone viruses!
4.
Now that the invasion is over, what will your immune system do to prepare for future attacks from Frank’s relatives?
5.
6.05- fetal circulation
Using your knowledge of fetal circulation, and the respiratory and digestive systems, fill in the chart provided. It compares and contrasts fetal circulation and circulation after birth. A sample box has been filled in for you. PICTURE OF CHART PROVIDED AS FILE
