but is the bones of the leg in our syllabus don`t think so... i know that students from queen elizabeth loves to learn more than necessary but not like this!!!They HAVE to, LOL These were apparently the only 3 points to give: humerus=femur, radius+ulna=tibia+fibula, carpals+metacarpals+phalanges=tarsals+metatarsals+phalanges What else was there to write?
Well most of my friends wrote about either the one which took less time to turn purple or even the one which had a deeper purple colour. Some even wrote about pepsin but i didn't. If some of my friends have written about pepsin then it must be correct because RCC boys are always correct!!!(sarcasm)Here's a brief part of my answer:
Crush up an exactly same volume of each seed. (say 2 cm3). Place both in separate test-tubes, which are in turn placed in water baths at the exact same temperatures of around 37 degrees. Add an exactly same amount of pepsin to both test-tubes. Making use of the Biuret test (NaOH solution followed by CuSO4), the time taken for all the protein to be digested in both test-tubes is recorded (at regular intervals, and then the final time, when all the protein has been digested). A graph can be plotted with the results. The one in which more time has been taken for all the protein to disappear hence contains more protein than the other.
I never learnt about this, just improvised. Therefore I am doubtful about it.

hahaaa....and u wil be getting bony marks!!!
isnt it added to activate the enzymes?I said it was to act as a control, so that all results obtained in the test-tube C could only be attributed to the presence of NaCl.
lol...Good for you. I learnt them from my sixth grade brother
hope thats true..no i didnot get exact graphy , i didnot know whether to draw best fit or wat , since they didnot mention
if we see previous Examiner Report and MS , they give No , for Labelling axis , 2 no for Axis , one for correct points and one of Line
so only one wud be deducted in case , if they checked best fit
it was the radiclein that biological drawing, what was seen? radicle or plumule?
I wrote pericarp, seed coat, endocarp and cotyledon. will those be wrong? :/both were seen\
Radicle was seen. Testa and cotyledon as well.in that biological drawing, what was seen? radicle or plumule?
If it is not mentioned, you have to connect the points. I did.Did u guys get exact graph? i drew a graph of best fit..
I connected the points as well. Did you get an optimum of 5 when connecting the points?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
