If I said the vaccine contained dead pathogen instead of weakened, would I lost the mark?

Pretty sure I put t-test 👊🏽👊🏽👊🏽 hopefully lol. Did you not feel that there was some really bloody easy questions? Like that one about the phospholipid vs triglyceride I was like what is this!

The first part of the paper was SOOOO kind I totally wasn't expecting it!!! Tbh was a pretty good paper throughout so I'm satisfied haha what about you? I have chem tomorrow sigh. Also, when you were evaluating the student's opinion on the mitotic spindle, could you find any evidence that supported his argument that 100nmol/dm^3 was the most appropriate concentration of KI? I only found one hahaha :/

I put prospective studies, as the condition of the candidate is observed and tracked over a period of 9 months since the initial.

But it was a comparison of statistics. Wouldn't it be T-test as a comparison between two results?

If someone can get me a copy of the paper or can remember most the questions I can put together an unofficial mark scheme.

I have chem toooooo I'm dreading it 😖😖 been focused on biology I barely revised chem haha.

I put that the % (or whatever it was) below was lower as evidence for the students results but that was the only thing! What did you get for the magnification and for the rate at 10 minutes?

Similar / same active site shape to each other which is complementary to the substrate

Posted from TSR Mobile

I put that it's becauze of the induced fit model, the substrate doesn't have to be the exact same shape as the active site, it just has to be similar enough for the active site to change slightly to accomodate it

Same, my teacher is shockingly bad. It's at the front of the revision guide though! It was only one mark, it's okay!!

Hey so did I! I think the marks would be for saying similar active site and complementary shape though.
