Biology cie AS level m/j paper 21 2019

How did you guys find the paper? What did you write for 1,2,3
And for X and Y?
I found it okay, some questions were weird though especially the wording... I got pulmonary vein, pulmonary artery and right atrium for 1,2, and 3. I did rough endoplasmic reticulum for X and mitochondria for Y....

I wrote 1. Pulmonary Vein 2. Atrioventricular valve and 3. Right atrium
For x rough endoplasmic reticulum and for Y I wrote vesicles
yeah I've seen that's what people have been putting ahhh.... some people put semilunar valve as well for number 2... what did you put for reason triglyceride and phospholipid are not monomers?

Same, do you think the threshold will be high or low?
honestly don't know, initially I thought it would be low but people in my class think it will be high, lets just hope for the best haha

yea, I don’t think it will be that high since I’ve seen so many different answers for 1,2,3 and X and Y
