Here are the answers to the first lot of questions we were given. Let me know if some don't make sense as they were just the marking points that ew were given. Some might take a bit of expalining. I will try and post the second lot if we get them and have gone through them in class.

Hey how did u guys answer this question of IAL scientific article??
1) Would you expect to see a difference in the % incidence of A1AT deficiency between males and females? Why? (2)
The answer is already given by one of the members of xtremepapers...but I am not getting the answer cz I dont know how we come up to this answer? Because there is nothing mentioned about whether it has sth to do with the gender in para 14.....I am not getting it... :S Not even one clue is given about the genders and all

This is something we were given to help us prepare with this - it isn't menat to be the questions you will get, but just something to help us think about the other topics that may come up. Hope its useful.

this is a question regarding the article
in para 10 (IAL one) it says that there is a rare genetic tendency to develop COPD called A1AT deficiency
why is rare?
any responses will be highly appreciated
thanks alot

thanks alot

anything is rare when very little of it is present. very few people may have a1at deficiency thats why it is rare or the chance to get a1at deficiency is very very less so its rare.
hope that helps
