How was Bio P34 ?!?

[confused123]

How was your practical guys? What about the graph question, the independent variable was H202 and dependent was time, right? :/

Went good Yes the concentration was independent variable and time was dependent one.

yes good ppr
wat was actual diameter?

That's it! awesome! I did the other way. took time at x-axis :| , how many marks gone?

 

[MsbhS22]

1

1 or 2 I guess

It was something in 200s. Dont remember the exact value

 

[Natashakhan]

yess

the actual size of the healthy lung alveolus was 234 um ..around this value.

 

[confused123]

What about the differences in photomicrograph of fig 2.2 and 2.3 i.e healthy lung and unhealthy lung..

ok.for the concentrations of plant extract i took the volumes correctly as in recorded them correctly in the table.but due to calculation mistake my concentrations noted down on the table wasnt right.how many marks gone?for the nest qs where they want time..will they also cut marks for the wrong concentration written there or will they just mark the time?

 

[MsbhS22]

Ummm.. is it allowed to discuss practical paper before 24 hours??

not at this forum. don't disclose the question clearly or don't be so specific and avoid getting into details. general discussion is fine...

i guess 2 3 marks..what volume u wrote and what mistake you did in writing concentration?

I think I made one more layer in the plan diagram? Can some one provide me a correct pic?

And I attempted my h2o2 question later. by that time it had turned to water :/

u should be asking the teacher that u had to change it with another new H2O2

 

[misof'tegame]

couldnt record the results properly ....how many marks do i lose?anyone?

I did my microscope question first too because there weren't many people taking this course and CIE people only sent a few slides. However, my teacher covered the H2O2 with a petri-dish and it stayed perfectly fine ~

oh the volumes i wrote were right.for example 2cm3 for plant extract 8cm3 for water and so on.each concentration had volume of 10cm3 but my highest conc. went upto 20% which is wrong.so 2-3marks?and the next qs where they wanted the time to b recorded in a table we also had to write the concentration there.will they cut marks for this same thing in there?

 

[The Munchkin]

The paper was relatively easy but i'm really worried about GT...

I heard that the time won't be enough for paper 2, I hope the CIE people also made P2 easier...

What do you mean "highest conc. went upto 20%" ?
