okay so my best guess is mineral ions.. it hasnt come up in a while.. also it is definitely 100000% not going to be antimicrobial as it came up in jan 14 and in this year's unit 3 paper as well! .. also the one on mitosis is my second best guess .. tensile strength is highly unlikely again for the same reason as antimicrobial.. it has come up too many times..
totipotency however keeps haunting me lol so that also so in order: 1) Mineral Ions ( 70%) 2) Mitosis (20%) 3) totipotency (10%)
lol this is just my prediction ..don't take it too seriously ..make sure you revise all experiments thoroughly because edexcel is unpredictable
OKAY GUYS vote above.. please don't base your vote on my opinion.. if you see a likely pattern vote according to that and mention it on the thread as well!
It would be helpful if you guys would ask individual questions you feel unsure about,I think it's easier to recall answers during the exam when you've seen them on an Internet forum..
