Guys q1 serial dilution was easy setting up the experiment was easy but while checking the ph was the hard part

 

[begna the benguin]

I dont think it will be that low.Definetly 31-32 because in 2017 and march 2018,thresholds were somewhere there.

dude this paper was hard af you did 33 we did 34

Idk what was wrong with it
at x10 it was a bit visible but at x40 I couldn't see anything
Anyways, the rest of the paper was quite easy I guess

true but ph paper was messed up

 

[A*****]

The microscope question also destroyed me upto some extent xD but rest paper 33 was pretty easy as well and inshallah lets hope for an A! .
Me:Mom I got a B in practicals!
Mom:Come here
Me:HERE FOR THE TREAT!
Mom:strangles me,

Lol treat on a B?

We'll be given some leniency for that IA

I think 2017 had simple food tests even in p34 or something easier. And making slides rarely comes so I do not think it will be that high.. 32 is too high.

Slide making is not that hard and does not take much tym but I don't know what was the pblm today

dude hisham did 33 maybe it was easy

 

[begna the benguin]

this one I HOPE THRESHOLD IS 26 to 29
for a not more than 30 max

 

[Kanekii]

I couldn't see the cells in the microscope

Same here and the fact that they provided me with a broken microscope which couldnt move the slide so i had to do it manually.

 

[begna the benguin]

how was q1 dude

 

[A*****]

Would be 29-31 for an A I guess

 

[Kanekii]

how was q1 dude

Pretty good since all the colours that i got were yellow
Im being sarcastic xD

 

[begna the benguin]

hmm cool

They were almost yellow but I got a few being pale red, reddish yellow and orange yellow at lower concentrations which means that CO2 was produced in a significant amount in them

I hate nerds

Same. The weird thing is, I added a drop of water onto the pH paper and there was literally no change.

Anyone else had moving cells in 34?

 

[A*****]

I hate nerds

Dude I'm not a nerd

 

[A*****]

Anyone else had moving cells in 34?

Yeast cells would be alive so natural for them to move

 

[Kanekii]

Ayeee, looked pretty fascinating though
