The following is an excerpt from the case study “It’s All Greek to Me”:

Dr. Stephens calls Mr. and Mrs. Stamos [and tells them]…’I am sorry to give you bad news. Nikoleta does have anemia [and] Nikoleta’s disorder has a genetic basis.’ ‘But neither one of us has any of the problems Nikoleta has. We aren’t tired all the time. We work out every day,’ replies Mr. Stamos.”

What is the basis for Mr. Stamos’s response? (2 points)

	Anemia, reduces the amount of nutrients reaching body cells and can be passed on through DNA.
	Anemia, reduces the amount of oxygen reaching body cells and can be passed on through DNA.
	Anemia, reduces the amount of water reaching body cells and is passed on by airborne viruses.
	Anemia, reduces the amount of protein reaching body cells and is passed on by airborne viruses.

The following is an excerpt from the case study “It’s All Greek to Me”: “I am sorry to give you bad news. Nikoleta does have anemia but, unfortunately, giving her a high iron formula was exactly the opposite of what should be done. Nikoleta’s disorder has a genetic basis.”

Iron is an important structural component of hemoglobin. Explain why this treatment failed and how the true cause of Nikoleta’s anemia was discovered. (5-8 sentences)
