I said just look at the intensity of the colour of solution if darker then more sugar present if light then less.
What did you keep why they are said models?

i said for models due to specific active site and specific substrate ???
did you put like me for the non reducing?

I don't know but as far as I reckon its just 5 of them

wait only said write nutriton write? so only wrote heterotrophic?

ya dats right I don't even know why I wrote parasitic. :biggrin:

then what did you keep for the organism that had divided nuclei or sth and have strands? I kept fungi

The identity of a new species??? I couldn't decide between Fungi / Protoctist but put fungi down at the last minute?

You can't caculate transmission without a calorimeter, I said use different concentrations of reducing sugars and use them to compare and find a qualative or quantative result :smile:

is my method wrong you think not even 1 mark for stop watch and using light ?

I wrote exactly the same, but then dnt know with ocr, questions on enzymes were totally out of spec, well at least didnt fit the past paper pattern.

I put these aswell, to begin with i put crap about the size of fish and stuff then realised xD

i said that they were models as the were like representives of what goes on in the body of an organism,, deffo wrong

What did people put for that, question when it was asking what organism it was?! Had is had multiple nucleus and thread like structures through the cytoplasm or something, i put fungi? :frown:

annd i found it really hard! nothing on the immune system i was well annoyed about that! I guess my dreams of becoming a dentist are down the drain :frown:

In question 7, what was the definition of the last word?

I put biodiversity, but it could've been species evenness :P

i put protoctist.
didn't have a clue.

To be fair, I learn the entire exam content in one weekend.

yes i wrote fungi as well :wink:

what did you do that was funny the song lyric lool !
did you put selective breeding , inbredding isolation ?>

for the antibiotics one i crossed out antibiotics and put drugs :/ silly silly silly!!!1

for the reducing sugar question you needed to have said you do the benedict test, get the precipitate , filter it, weigh and and compare it to calibration graph you did earlier using data from known glucose concentrations. i think weight on x axis and conc. on y axis

I think it was fungi but I hope it wasn't because I just realised I put protoctista fuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

yup talked about artificial selection and stuff
what did you keep for why they are said models and why induced fit accepted?

For the question about similarities and differences between agarose and amylose...

I put they are both straight chain, i.e. neither of them are branched
And that Agarose has 1-3 glycosidic bonds as well as 1-4 bonds, whereas amylose just has 1-4 bonds.

Do you think this is right???

I dont understand why no one write that similarity is that they both are polysaccahrides

and difference is that agarose has more than one component sugar where amylose is just contains alpha glucose

this is the right answer
