guys .... Can somebody answer me with the questions i asked in page 2 plzzz
cuz i wana check these answers !

 

[Feelguud77]

I actually tried placing the 5cm^3 syringe in the tube and all that did was spill its contents must say little bit of a klutz
but hey, i got a brand new microscope since i was the first roll no. in the lab perks!!

 

[blablabla]

how was the serial dilution thing????

 

[Romeo10]

What did u do in the hypothesis question ----- below conc. 0.03% copper sulfate do not inhibit the enzyme activity ???????
As for me , i said that the hypothesis is supported in 0.00003% as it reached the end-point in time as W while the hypothesis is not supported in 0.0003%
and in Q2 where is the air space labelled ???

 

[libra94]

the time was increasing as the conc. was decreasing , right??????

 

[girlscampisra]

what similarities and differences did you guys write?

 

[Feelguud77]

That was kinda obvious
Serial Dilution: 10 cm^3 E + 10 cm^3 W= 5% E
10cm^3 of 5% + 10cm^3 W =2.5% E
10cm^3 0f 2.5% + 10cm^3 W= 1.25% E
and so on........10cm^3 of final goes to waste( or washing....meh, doesnt really matter)

 

[girlscampisra]

yes thats right! tell me about question number 2.

 

[Feelguud77]

Atleast one similarity.............Both have trichomes( i heard this for the very first time in the exam and was like Tri....wha? )
Differences:
K1 has vascular bundle visible, fig2.2 not
K1 Palisade layer long cylindrical cells,fig2.2 irregular/ amalgamated
K1 Trichomes widespread, fig2.2 many in close proximity
K1 Inter(or Intra)cellular spaces present, fig.2.2 none observable

.........umm yeah thats pretty much it

 

[filza94]

lolzzzz......til now u remember wat u rote.......!!!!!

 

[Feelguud77]

What you write in exams has a way of.................sticking to your mind

 

[girlscampisra]

shit, i'm gonna lose marks here !!

 

[filza94]

ohh yeah yeah wateva...!!!

 

[Feelguud77]

What i wrote hasn't been etched in stone ya know
theres a plethora of possible answers, anything you observed ,you wrote, the rest is up to the examiner!

 

[filza94]

hmm ......

 

[girlscampisra]

yes, lets keep our fingers crossed!!
i hope this paper has a low GT, thats the only way to score A now!

 

[filza94]

i agree wid u girlscampisra..!!!!

 

[Feelguud77]

lol, go with the flow

 

[Romeo10]

what was the answer of the hypothesis question...... Of enzyme inhibition of CuSO4 conc.below 0.03%
