    Gall bladder, spleen and liver are the best answers...and deudonem makes more sense to me than pancreas does since they're both at approximately the same distance from the stomach but the intestine is actually connected to it :/

    The pancreas isn't even that close. The spleen and the bile duct could be affected. I wrote small intestine though...when the sphincter muscles contract, the deudenon would open and the infection could be passed on to it

    Lol :p lupins can be asexually reproduced btw...says so on google. Yeah the question asked why there's a wider variety of colors, so that's the first thing that sprang to my mind, especially after doing the cultivated and wild bananas question just a day before the exam :p

    I don't know. I thought it was like that wild and cultivated bananas question in the past papers. Actually I'm not sure what I wrote...I keep confusing it with the crops question, which asked us why the plant grown in the large buildings are going to grow less or something

    Commercial lupins are produced sexually so they have greater colour variations and have more viable seeds, as opposed to wild lupins which are asexually reproduced...or maybe it was the other way round. I can't remember the question. It could've been cross and self pollination (but that was in...

    Since so many people wrote biotechnology, I really hope that they accept it. Besides, the antibiotics are a bio product which they excrete, so the answer should be excretion..I mean that's how they're produced :S

    Oh I also wrote about how the organs (eg diaphragm, ribs,sternum) won't be able to move properly, so the amount of air entering and exiting the lungs would be greatly reduced. Bleh I forgot to write about damaged blood vessels x_x that's probably the most important point
