How was Biology?

[ahmadumar]

Can ny1 pls temme wat wer d 2 biological functions of d onion ??

never heard about da biological functions of onions!
you doing code 5090. ryt?

 

[ritesh isuri]

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?

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!!!

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.

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)

Well at least I'm not the only one with that answer. And logically speaking, i don't find anything wrong with it.

LOL dude. More is always better than less. My school teacher did it anyway.

 

[me_lonelyboy]

and u wil be getting bony marks!!!

hahaaa....

 

[me_lonelyboy]

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.

isnt it added to activate the enzymes?

 

[me_lonelyboy]

Good for you. I learnt them from my sixth grade brother

lol...

 

[me_lonelyboy]

in that biological drawing, what was seen? radicle or plumule?

 

[me_lonelyboy]

Did u guys get exact graph? i drew a graph of best fit..

 

[me_lonelyboy]

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

hope thats true..

 

[ritesh isuri]

it was the radicle

 

[Nerdz]

Didnt we have to connect all the points in the graph?

 

[Nerdz]

both were seen\

I wrote pericarp, seed coat, endocarp and cotyledon. will those be wrong? :/

 

[Miss_Z]

I wrote testa, cotyledon, radicle, plumule I think.

 

[Miss_Z]

I also wrote hilum where there was a scar -_- but nvm, at least I got the 4 others. And yeah, this is not a fruit, so no pericarp, mesocarp etc!

Radicle was seen. Testa and cotyledon as well.

 

[Jilva_02]

If it is not mentioned, you have to connect the points. I did.

 

[Miss_Z]

I connected the points as well. Did you get an optimum of 5 when connecting the points?

 

[Jilva_02]

Yes.
